Description

How to develop scents using colors

The present invention relates to a method of developing a scent using color.

The scent plays a major role in human life, and for example, in foods, drinks, luxury items and cosmetics, the image of the scent possessed by them is one of the major factors in quality judgment.

It was very difficult to accurately convey the image of scent to other people and share the image with other people. For example, it is common to use letters (or language) as a method of expressing scents, but due to differences in the meaning and interpretation of the letters and the images associated with those letters, the scent image can be shared accurately. There wasn't. As a result of not being able to accurately share the scent image, it becomes a big problem especially when changing the scent of an existing product or determining the scent of a new product, among the person in charge of product development of foods, drinks, cosmetics, etc. Was there.

In Patent Document 1, a plurality of subjects selects a color of an image corresponding to a scent to be visualized, selects each color selected by each subject as one or a plurality of color element units of the same area, and the subject selects There is described a method for quantifying a quantitative characteristic of a scent, which is characterized by obtaining an average value of lightness values based on all the color element units described above and expressing the quantitative characteristic of the scent with this value.

In Non-Patent Document 1, the experiment collaborators are allowed to select a plurality of colors (specifically, three types) from 18 kinds of colors expressed two-dimensionally of hue and tone, and harmony of colors and fragrances. I'm considering sex.

In addition, in the present specification, the numerical range represented by "-" means a range including the numerical values before and after "-" as the lower limit value and the upper limit value.

[Scent development method]
The scent development method of the present invention includes a direction visualization step for expressing and visualizing the direction of a scent to be developed by a color expression diagram, and a candidate scent visualization for expressing a single or a plurality of candidate scents by a color expression diagram for visualization. And a selection step of selecting at least one of the candidate scents as a scent with a high degree of matching with the directionality together with a color representation diagram that visualizes the candidate scent.
With this configuration, according to the present invention, it is possible to select a scent having a high degree of agreement with the directionality of the scent to be developed.
In the present specification, unless otherwise specified, "fragrance" includes a fragrance, a fragrance composition and a flavor composition. That is, the "fragrance" also includes flavors (also called flavors) including taste. However, in the present specification, in particular, when distinguishing the "scent" perceived by the sense of smell and the "flavor" perceived by the sense of smell and taste, the "scent" and the "flavor" are expressed in parallel, or independently. May be described as "flavor".
The color representation diagram preferably used in the present invention will be described later. Since the information of the color expression diagram is information that can be easily transmitted, managed and stored, it can be transmitted in a short time using e-mail or the like and can be stored as data on a personal computer. In addition, since the characteristics of the image such as the scent are expressed in a color representation diagram without using words, the characteristics of the image of the scent or the like can be transmitted as objective data with little individual variation and high reproducibility.
Hereinafter, preferred embodiments of the present invention will be described.

<Direction visualization stage>
The scent development method of the present invention includes a direction visualization step of visualizing a scent to be developed by expressing it in a color representation diagram.

(Direction of scent to be developed)
The direction of the scent to be developed is not particularly limited, and the scent direction of others (especially the person in charge of product development of foods, drinks, luxury items, cosmetics, etc.) or the scent developer himself Also, the scent development method of the present invention can be applied.

For example, the direction of the scent to be developed may be an image not related to color or an image related to color. Examples of images that are not related to color include a product concept, flavor (keywords related to flavor of food and drink), keywords other than flavor that are not related to flavor, images of people, images of emotions, and the like. As images related to colors, specific color names (color name, common name, system name, color order system, etc.), color tone (tone), expression that recalls a specific color (colorful, instagrammable) , Illusion, etc.), and color schemes based on the theory of color harmony.

On the other hand, even when the directionality of the scent to be developed is not embodied in the first place, the scent development method of the present invention can be applied. When the directionality of the scent to be developed is not specified, it is preferable to include a step of determining the directionality of the scent to be developed in the initial stage of the direction visualization step.
There is no particular limitation on the stage of determining the direction of the scent to be developed. For example, the method of determining the direction of the scent to be developed can be changed depending on whether the product for which the scent is developed is an existing product or a new product.
In the case of an existing product, it is preferable to acquire information on the existing product. When acquiring the information of the existing product, it is more preferable to acquire the color data of the existing product, the sensory evaluation, the consumer survey, and the like to acquire the information about the characteristics of the existing product. Then, based on the obtained information about the characteristics of the existing product, it is preferable to determine the direction of improvement of the existing product through acquisition of emotion color data, acquisition of fragrance / flavor color data, consumer survey, and the like. .. As a specific method, for example, the scent or flavor of an existing product can be expressed in a color representation diagram and visualized, and the direction of improvement of the existing product can be determined. In addition, a consumer questionnaire or the like may be conducted on the scent or flavor of the existing product to determine the direction of improvement of the existing product. In this case, the direction of improvement of the existing product that is the target of fragrance development is determined by comparing the scent and flavor of the existing product that is the target of fragrance development with another existing product (for example, a product that serves as an index). be able to.
On the other hand, in the case of new products, it is developed based on information about emotional color data, fragrance / flavor color data, and specific product concepts (keywords, flavors that are the basis of new products, colors of new products, etc.). It is preferable to determine the directionality of the scent to be produced.

Below, we will explain the preferred aspects of the direction visualization stage by classifying them according to the type of color representation diagram used and the type of directionality of the scent to be developed. In addition, you may combine 2 or more types with a preferable aspect among the preferable aspects divided into the following cases.

-(1) Using a color expression diagram of the scent or flavor of an existing product and a color expression diagram relating to the direction of improvement of the existing product (when including step A1, step A2 and step A3)-
In the scent development method of the present invention, it is preferable that the directional visualization step includes step A1, step A2 and step A3.
Stage A1 of visualizing the scent or flavor of the existing product by expressing it in a color diagram.
Step A2 of visualizing an image of a scent, flavor, emotion, or other words, an image of a person, or an actual scent, flavor, or emotion in the direction of improvement of an existing product by expressing it in one or more color representation diagrams.
Step A3 of creating a color expression diagram expressing the directionality of the scent to be developed, based on the color expression diagram expressed in step A1 and the color expression diagram expressed in step A2.
Here, the steps A1 to A3 are not particularly limited.
In step A1, for example, the results of sensory evaluation by a plurality of test subjects can be expressed in a color expression diagram. Here, one of the important factors is who evaluates the subject. It is preferable to properly set the number of subjects and attributes (nationality, sex, age, occupation, etc.). The attributes preferably assume consumers of the product for which the scent is developed.
In step A2, the same subject as in step A1 may be visualized by expressing each type of image, actual scent, flavor, or emotion in a color expression diagram. Alternatively, an existing database of color representation diagrams for each type of image, actual scent, flavor, or emotion may be used.
As the step A3, for example, a color representation diagram averaged from a plurality of color representation diagrams, a color representation diagram expressing differences of images to be improved by colors, a color representation diagram of an existing product itself, or an image related to a color directly It is possible to create the created color expression diagram.
There is no particular limitation on the method of creating an averaged color representation diagram from a plurality of color representation diagrams. For example, in a color expression diagram created by performing the first to third steps described below, the sum of the values corresponding to the contribution ratios of the respective colors is further summed among the color expression diagrams of a plurality of keywords to obtain the number of keywords. A color expression diagram can be created from the average value divided by (or the average value converted into a ratio).

FIG. 13 shows an example of the direction visualization stage including the stage A1, the stage A2, and the stage A3. In step A1 of FIG. 13, a consumer survey of a specific existing product is performed, and a fragrance color expression diagram (petal diagram) of the specific existing product is obtained by a method including first to third steps described below. It was created, and the color representation diagram on the upper left of the paper was obtained. In step A2 of FIG. 13, after determining the direction of improvement of the existing product to refresh, which is a keyword other than the flavor related to the direction of improvement of the specific existing product, a method including first to third steps described below is used. A color expression diagram (petal diagram) of the image of the word "refresh" was created, and a color expression diagram at the lower left of the paper was obtained. In step A3 of FIG. 13, a color representation diagram averaged from the color representation diagram of the specific existing product and the color representation diagram of the image of the word “refresh” is created. The obtained color expression diagram on the right side of the paper (existing product + average refresh) was used as the color expression diagram expressing the directionality of the scent to be developed. The averaged color representation diagram is the sum of the values corresponding to the contribution rates of the respective colors when creating the color representation diagram of step A1, and the sum of the values corresponding to the contribution rates of the respective colors when creating the color representation diagram of step A2. Was further summed and divided by the number of color representations (two) to create an average value.

As another preferred embodiment, FIG. 14 shows another example of the directional visualization step including step A1, step A2 and step A3. In the example of FIG. 14, using the same color representation diagram of the specific existing product (upper left of the paper) as in FIG. 13 and the four color representations created in step A2 (lower left of the paper), five colors are displayed in step A3. A color representation diagram (not shown) is created from the average of the color representation diagrams and used as the color representation diagram that expresses the directionality of the scent to be developed. In step A2 in the example of FIG. 14, a color expression diagram of emotion images of “refreshing” and “refreshing”, and “lime” and “lime” by a method including first to third steps described later. A color expression diagram of the actual scent and flavor when "Sudachi" was consumed was created.

-(2) When using the color representation of the image of the existing product and the color representation of the improvement direction of the existing product-
The scent development method of the present invention includes a step of visualizing an image of the first product, which is an existing product, by a color representation diagram;
Visualizing the direction of improvement of the first product in a color representation diagram;
A scent direction that creates an average color expression diagram created from the color expression diagram expressing the image of the first product and the color expression diagram expressing the direction of improvement of the first product, and develops the average color expression diagram It is preferable to include the step of setting the sex.
The first product is an existing product.
At the stage of expressing and visualizing the image of the first product which is an existing product by a color representation diagram, one of the important factors is who evaluates as a subject, and the preferable mode of the subject is the same as the preferable mode of step A1. Is.

-(3) When using a color expression diagram of a keyword other than flavor of an existing product and a color expression diagram of a plurality of flavor-related keywords of an existing product-
The method for developing a scent of the present invention is a color expression diagram for a keyword other than flavor when the directionality visualization step is a keyword other than flavor that is not related to the flavor of the first product, which is an existing product. Including the step of visualizing by expressing with;
Including a step of visualizing a plurality of flavor-related keywords related to the flavor of the first product in a color representation diagram;
Including a step of ranking the similarities of the flavor-related keywords to the non-flavor keywords based on the similarities between the color representation diagrams of the flavor-related keywords and the color representation diagrams of the non-flavor keywords;
It is preferable that the selection step is a step of selecting at least one of the candidate scents as a scent having a high degree of agreement with the directionality based on the order of the flavor-related keywords.
As described above, the first product is an existing product.
As a keyword other than the flavor, for example, when the development target of the fragrance is a lemon flavored beverage, the direction of the fragrance to be developed is “adult-like”.
Flavor-related keywords include “acidity”, “sweetness”, “juiceiness”, “freshness”, “peelness”, etc., when the target of flavor development is a lemon-flavored beverage. it can. In addition, keywords such as "bitter feeling", which is unlikely to be associated with the lemon flavored beverage for which the fragrance is to be developed, are included in the flavor-related keywords because they correspond to the flavor of the beverage.
Based on the similarity between the color representation diagram of a plurality of flavor-related keywords and the color representation diagram of a non-flavor keyword, the step of ranking the similarity of the plurality of flavor-related keywords to the non-flavor keywords may be included. It is preferable from the viewpoint that it becomes clear whether the feature can express an image of a keyword other than flavor, and it becomes easy to select a candidate scent and to determine the direction of perfuming. In fact, the candidate scents are selected and the fragrance is based on the flavor, and thus the flavor-related keywords are easier to use as an index than the non-flavor keywords.

In this aspect, it is preferable to include a step of performing a sensory evaluation on the candidate scent based on the relevance to the flavor-related keyword and confirming the high relevance of the selected scent to the flavor-related keyword.
Further, it is preferable to include a step of performing a sensory evaluation on the candidate scent based on the applicability to keywords other than flavor and confirming the high applicability of the selected scent to keywords other than flavor.
Further, in this aspect, it is preferable to include a step of deriving an improvement direction of the first product, which is an existing product, from a consumer questionnaire regarding the first product.

-(4) When using a color expression diagram of a product concept of a new product (when including step B1 and step B2)-
In the scent development method of the present invention, it is also preferable that the direction visualization step includes steps B1 and B2.
Step B1 of visualizing an image of a scent, flavor, emotion or other words related to the product concept of the new product; an image of a person; or an actual scent, flavor or emotion by using one or more color diagrams.
Step B2 of creating a color expression diagram expressing the directionality of the scent to be developed, based on the color expression diagram expressed in step B1.
Here, the step B1 and the step B2 are not particularly limited.
In step B1, who evaluates as a subject is also one of the important factors, and the preferable aspect of the subject is the same as the preferable aspect of step A1. Regarding emotions, it is preferable to make detailed settings for scenes and conditions.

When the directional visualization step includes the step B1 and the step B2, the directional visualization step further expresses a plurality of keywords included in the product concept of the second product, which is a new product, by a color expression diagram, and obtains a plurality of obtained keywords. It is more preferable to include a step of creating an average color representation from the respective color representations of the keywords, and developing the average color representation as a scent direction. With this method, the product concept of the second product, which is a new product, is not clear, and even if there are multiple concept word candidates, the scent is selected according to the image of the group of concept word candidates. be able to.
The second product is a new product.

-(5) When the color representation diagram of the image of the person includes the step of setting the direction of the scent to be developed-
In the method for developing a scent of the present invention, the direction visualization step is performed such that an image of a person who is a consumer of the third product, which is an existing product or a new product, a person related to the advertisement of the third product or a fictional person. Image, the image of the person who yearned for the consumer of the third product, or the image of a person who is a celebrity is expressed in a color expression diagram, and the direction of the scent that develops the color expression diagram of the obtained person image It is preferable to include the step of
Examples of fictitious persons include characters in TV dramas and movies.
The third product is an existing product or a new product. The existing product or the new product in “(5) In the case where the color expression diagram of the person's image includes the step of setting the direction of the scent to be developed” is conveniently referred to as the “third product”.
The celebrity includes a symbolic person, and includes a person whose actual name recognition is low. For example, a person who can imagine a lifestyle like a celebrity, a privileged person or a celebrity inside or outside Japan is also included.
When the image of the person who is the consumer of the third product (existing product or new product) is represented by a color representation diagram, it is possible to provide a tailor-made product that matches the consumer's individual image. It is possible to provide a product having an image suitable for the individual consumer image by creating a consumer individual image and a color representation diagram of the product, and confirming the similarity of the color representation diagrams. For example, it is preferable to select a tailor-made perfume that matches the individual consumer's image. FIG. 10 shows an example of a color representation diagram of an image of a person and a color representation diagram of a fragrance of a perfume, which is similar to the color representation diagram of the image of the person when selecting a tailor-made perfume that matches an individual consumer. It was In this example, regarding the image of the person A who purchases the perfume, the color of the image of the person A is measured by a method including a first step to a third step described later by conducting a questionnaire for a plurality of persons who know the person A. An expression map (petal map) was created and used as the direction of the scent to be developed. Confirm the similarity between the direction of the developed scent (color representation of the image of person A) and the color representation of perfume of some existing products, and the similarity between the color representations described below. Steps were taken and the most similar perfume D was selected. The color representation diagram (petal diagram) of this perfume D is the color representation diagram on the right side of the paper surface of FIG. 10.
The color representation diagram of the perfume of the existing product may be newly created, or a database of the color representation diagram of the existing perfume prepared in advance may be used.
The fragrance development method of the present invention includes cases in which the development stage of perfumes and new fragrances is not included. For example, a product with a high degree of matching is selected from many existing products and matched with consumers. An embodiment in which the steps are completed is included.

-(6) When the color representation diagram of emotion data includes the step of setting the direction of the scent to be developed-
In the method for developing a scent of the present invention, the direction visualization step creates a color expression diagram of emotion data to be given to consumers of the fourth product, which is an existing product or a new product, and develops a color expression diagram of emotion data. It is preferable to include the step of setting the direction of the scent.
The fourth product is an existing product or a new product. The existing product or the new product in “(6) When the color expression diagram of emotion data includes the step of setting the direction of the scent to be developed” is conveniently referred to as the “fourth product”.
There is no particular limitation on the emotion data that the consumer wants to give. In this case, it is particularly preferable to include the step of deriving emotion data from a consumer questionnaire regarding emotions. With regard to (actual) emotions, it is preferable to make detailed settings for scenes and conditions and to conduct a questionnaire. It is preferable to embody when, where, etc. as a scene. For example, it is preferable to set such as "emotions of eating breakfast at home in the morning". It is preferable to embody ideal, reality, past, future, etc. as conditions. When setting the scenes and conditions, for example, "ideal feelings when eating breakfast at home in the morning" or "in the past (about 5 years ago) when eating breakfast at home in the morning" It is preferable to set such as "emotion". You may set only conditions.
FIG. 11 shows an example of a result of creating a color expression diagram of emotion data for women (20 people) having children in their 30s to 40s set as consumers of a new product (fourth product). The product concept in this case was "development of a new product that encourages married women in their thirties and forties". The six color representation diagrams shown in FIG. 11 are the first to third stages, which will be described later, for an actual emotional image in which the scenes and conditions described in each color representation diagram are set. It is a petal diagram created by the method including. For example, in the column on the left side of the paper in FIG. 11, the difference and / or average of the color representations of “[Reality] commuting” and “[Ideal] commuting” or “[Ideal] commuting” Determine the direction of the fragrance to be developed when developing the fragrance used during commuting and the scent of foods and drinks eaten and drinked during commuting, and develop scents that match the tastes of consumers. You can

-(7) When the direction of the scent to be developed is an image related to color-
When the direction of the scent to be developed is an image related to color, it is preferable that the direction visualization step includes a step of converting the image related to color into a color diagram to visualize. For example, if the product concept of a new product is a keyword related to color but an abstract keyword (instant look, etc.), convert the keyword related to color into a color representation diagram (colorful impression including multiple colors). It is preferable to visualize the direction of the scent to be developed.
This method is particularly preferably used when the direction of the scent to be developed is a color that matches the keyword regarding color or the fifth product for which the color is determined.
The fifth product refers to a color keyword or a product whose color has been determined, and may be an existing product or a new product.
In the upper part of the page in Fig. 12, the degree of agreement with the direction of the scent to be developed is shown when the new lacto ice product concept is converted into a color expression diagram and visualized to be the direction of the scent to be developed. The color representations in which the high scents of lacto ice A with candidate flavor A (upper left on paper) and lacto ice B with candidate flavor B (upper right on paper) are expressed in color are shown. In FIG. 12, the color representation diagram itself obtained by converting the keyword “instagram” regarding the abstract color to visualize is omitted, but a colorful color representation diagram including a plurality of colors is created as a representative example. The scents of Lactic Ice A and Lactic Ice B were the scents that seemed to be "Instant" (colorful impression), in agreement with the product concept "Instant". In this way, by selecting a scent that has the impression of a product concept keyword or product color from a specific product concept keyword or product color, it is possible to select a scent with a high degree of agreement with the direction of the scent to be developed. . On the other hand, for the evaluator, the degree of conformity with the directionality of the scent to be developed can be evaluated not only by words but also by color, which facilitates the evaluation.
In the lower part of the paper of FIG. 12, using the color representation diagram of the upper part of FIG. 12, photographs of lacto ice A (lower left of paper) and lacto ice B (lower left of paper) subjected to the color determination method described later are shown. The color of the lacto ice A and lacto ice B products themselves can be harmonious with the scents of the lacto ice A and lacto ice B (no discomfort), and also match the product concept "instagram". Met.
A color expression map of keywords (words) when converting an image related to color to a color expression map may be newly created, or a database of color expression maps of previously created keywords (words). May be used. For example, data of color representation diagrams of keywords (words) of images related to colors such as “colorful”, “orange”, “yuzu”, “muscat”, and “yogurt” can be stored in a database in advance.

Yes (the pattern similarity is higher when the number of subjects is large and more objective).
In addition, this method can reflect the subjectivity of the subject (worry that the image of pink is strong, but the image of black is a little mixed) in the contribution rate.
In this method, the expression diagram of one test subject (the value corresponding to the contribution rate thereof) is summed up for n people to be a “color expression diagram”.

-First stage-
In the first stage, s types (a ≧ 2, b ≧ 2, s ≧ 2) of color charts corresponding to an image to be visualized by a subject are selected from a color chart group including at least a × b types of color charts. Is preferably selected including the respective contribution rates p _s .

There is no limitation on the type of image to be visualized. It is possible to use each type of image mentioned as the direction of the scent to be developed. For example, a scent, a character, a person (a name of a person, a photograph, a real thing, etc.), a sound, a tactile sensation, a taste, and an image in which they are integrated (a fragrance and a taste, etc.) can be mentioned. The characters are not particularly limited. Characters such as hiragana, katakana, kanji, and alphabets used in Japanese, and characters used in foreign languages (for example, Hangul) can be mentioned. Similarly, the name of the person is not particularly limited, and may be the name of the person described in characters used in Japanese or the name of the person described in characters used in a foreign language.
It is preferable that the image to be visualized is an image of the scent that the subject smelled, an image of the flavor that the subject tasted, an image of the characters (words) that the subject saw, an image of the person that the subject saw, and an image of the emotion of the subject. .

The color chart group preferably includes at least a × b types of color charts.
Specifically, the color chart group includes a first system of a type color and a second system of b type color.

For example, a color system called PCCS (Practical Color Co-ornate System) developed by General Incorporated Foundation Japan Color Research Institute, which is mainly used for color harmonization, is a "JIS Z8721 color display method-three colors". In addition to the standard color chart created based on "display by attribute", the Munsell international standard color chart, a commercially available color chart or color chart may be used. Among these, it is preferable to select the hue and tone from PCCS. Examples of the hue of the PCCS color system include red, orange, yellow, green, blue and purple. Tones of the PCCS color system may include pale, light, vivid, deep and dark.

Examples of the third system relating to the texture of colors include achromatic color, metallic color (gloss), and pattern (color unevenness). Among these, it is preferable to use at least one of an achromatic color and a metal color from the viewpoint of increasing the possibility of matching the subjectivity of the color matching the image to be visualized by the subject. In the present invention, it is more preferable that the third system has a metal color of c = 2, and the metal colors are gold and silver. Further, it is particularly preferable to employ both an achromatic color and a metallic color.

The first direction and the second direction are not limited to linear directions from a specific start point, and may be arbitrary curved lines. That is, the color chips may be arranged in a distorted manner instead of the two-dimensional arrangement. However, it is more preferable to arrange at least a × b kinds of color chips two-dimensionally from the viewpoint of reducing the burden on the subject and improving the reproducibility.

The color chart selected by the subject is preferably s types (s ≧ 2). s is more preferably 2 to 20, particularly preferably 2 or 3, and particularly preferably 2.
It is preferable that the test subject includes the respective contribution rates p _s when selecting the s types of color charts. The contribution ratio p _s can be represented by a ratio or a percentage. Further, the total of the contribution rates of the s kinds of color chips to be selected may be less than 1 (= 100%). For example, the analysis can be performed even if the total of the contribution rates of the s kinds of color charts is 0.8 (= 80%) and the other colors are 0.2 (= 20%).
Preferably, the total contribution ratio is 1 (= 100%).

-Second stage-
In the second stage, it is preferable to create an expression diagram of the subject by assigning a value corresponding to the contribution ratio p _s selected in the first stage to each color chart forming the color chart group.
As a method of creating an expression diagram of the subject, a well-known pivot table analysis or the like can be used.
In the obtained representation diagram of one subject, the sum of the contribution rates given to all the color charts is preferably 1 (= 100%). As the value corresponding to the contribution rate of each color, it is preferable to use the selected contribution rate value (unit:%) of each color chart as it is.

When n is 2 or more, the number of types of color charts represented may increase by selecting the color chart corresponding to the image to be visualized by a plurality of test subjects, and many people are likely to see that image. It is possible to include many color charts that are judged to match on average. It is particularly preferable that n is 10 or more from the viewpoint that the visualization of the scent image is more reproducible and the image can be visualized so as to be intuitively shared with others.
In the obtained color representation diagram of the representation diagrams of the n subjects, the sum of the contribution rates given to all the color charts is n (= n × 100%).

A graph showing the relationship between the range including at least the first system of the color chart group and the value obtained by further summing the values obtained by converting the sum of the values corresponding to the contribution rate to the ratio for each type of the first system, It may be a color representation diagram.
In addition, the color representation diagram may be created by taking five types of tones and two types of third systems as the first system on the horizontal axis.

-Second mode-
The second mode of the color representation diagram is a color array table in which each color is arrayed in the same array as the color chart group;

(B2) The color palette has the number of stages determined by converting the sum of the values corresponding to the contribution rates of the respective colors into a ratio and normalizing it for each predetermined range of the ratio.

The second aspect of the color representation diagram is, among these, that the (B2) color palette converts the total of the values corresponding to the contribution ratios of the respective colors into a ratio, and standardizes it in each predetermined range of the ratio. Is preferred. By expressing the large contribution rate (voting rate) by the number of steps in the color palette, the image can be visualized so that it can be intuitively shared with others.

A preferred embodiment of the color array table in which each color is arranged in the same arrangement as the color patch group in the second mode of the color representation diagram is the same as the preferred embodiment of the color patch group of the method of expressing an image by color. For example, in the color chart group shown in FIG. 1, a color palette corresponding to the value obtained in (B1) is represented at a position corresponding to each color chart, or a color palette having the number of stages determined in (B2) is represented. ..
In the second mode of the color representation diagram, it is preferable that the shape of the color palette is a polygonal shape of a triangle or more or a circular shape. In the second aspect of the color representation diagram, the shape of the color palette is more preferably a polygonal shape of a triangle or more, and particularly preferably a quadrangular shape.

In the second mode of the color representation diagram, the (B1) color palette is represented using a sum of values corresponding to the contribution rate of each color or a value obtained by converting the sum of values corresponding to the contribution rate of each color into a ratio. In this case, a value obtained by dividing the value of n (= n × 100%) by n, that is, 1 (= 100%) is used as the total value. That is, the sum of the values given to each color chart is 1 (= 100%).
In the second mode of the color representation diagram, when the (B2) color palette has the number of stages determined by converting the sum of the values corresponding to the contribution rates of the respective colors into a ratio and normalizing it in each predetermined range of the ratio. , The values assigned to each color chart are standardized. The standard for standardization is not particularly limited. For example, one stage may be provided for every 3%, one stage may be provided for every 5%, and one stage may be provided for every 10%. Further, for the purpose of sharpening the characteristics of the color representation diagram, it is not necessary to provide a palette in the color representation diagram for colors for which only a ratio equal to or less than a certain threshold is obtained.

A petal diagram means having a core part and a color palette, and the color palette is arranged around the core part. It is a formally used expression for the purpose of making the shape of the color expression diagram easy to understand. . The description of “petal” does not limit the shape of the color representation diagram.
Arranging the color palettes in a direction substantially parallel to each side means that when the color palettes are arranged, the angle between the radiation from the inside of the core part where the color palettes are arranged on the extension line and each side Is approximately parallel + 90 ° (almost vertical). In the direction substantially parallel to each side, the angle formed by that direction and each side is preferably ± 20 °, more preferably ± 10 °, particularly preferably ± 5 °, and most preferably ± 1 °.

For example, the selection ratio of each color chart is a band graph (such as a 100% stacked horizontal bar chart), the same color as the color chart is attached to each element of the band chart, and the selection ratio of each color chart is visualized without standardization. An expression diagram can be given.

When using a candidate scent as a flavor and the flavor of the new product to which the flavor of the candidate scent is added has not been determined, the degree of conformity of the candidate scent to the directionality of the scent to be developed (in the color expression diagram) It is preferable to select the one with the highest possible value.
On the other hand, even in this case, if the flavor of the new product has already been determined, among the candidate scents, the degree of agreement with the direction of the scent to be developed (in the color representation diagram) is high, and the flavor of the new product is high. It is also possible to select a color expression diagram with a high similarity. A color expression diagram of the flavor of the new product can also be created by the method described above.
When a candidate scent is used as a flavor, the “color expression diagram in which the candidate scent is visualized” of the present invention also includes “a color expression diagram of the scent or flavor of the product to which the candidate scent is added as a flavor”. .

Is preferred.
The evaluator who sniffs the scent expresses the image whose scent he / she wants to change by using the colors included in the color expression diagram, thereby sharing the image of the policy of which he / she wants to change the scent with others other than the evaluator.
As the other person than the evaluator, for example, a perfumer or the like can be cited.
As a method of expressing an image for which a specific scent is desired to be changed by using colors included in the color representation diagram, it is possible to perform an expression such as one step increase or decrease of an arbitrary color included in the color representation diagram. Furthermore, it is preferable that the evaluator specifically creates a color expression diagram of the image for which the scent is desired to be changed.
If the evaluator who sniffs the scent wants to express the image for which he / she wants to change the scent using a color that is not included in the color expression diagram, use the color that is not included in the color expression diagram and is included in the color chart group. Is preferred.
A preferable aspect of the color chart group used in the fifth stage is the same as the preferable aspect of the color chart group used in the first stage.

After the evaluator makes an evaluation, another person other than the evaluator mixes a new scent to be visualized in the sixth step, expresses the new scent to be visualized in a color expression diagram in the seventh step, and the eighth step By confirming the similarity between the color expression diagram of the image that the evaluator wants to change and the new color expression diagram of the scent to be visualized, the evaluator can match the image of the policy that the scent should be changed. It is easy to add a new fragrance.

<Eighth stage>
The method of developing a scent of the present invention includes an eighth step of confirming the similarity between the color expression diagram of the image expressed by the evaluator who wants to change the scent and the color expression diagram expressed in the seventh step. It is preferable to include.
In general, there is no particular limitation on the method of confirming the similarity between an arbitrary color representation diagram and another color representation diagram. For example, the image similarity evaluation method described below can be used.
As the color expression diagram of the image that the evaluator wants to change the scent of, for example, when the evaluator specifically creates a color expression diagram of the image of which the scent is desired to be changed, the color expression diagram can be used. If the evaluator does not specifically create the color representation of the image for which the scent is to be changed, the perfume technician performing the fragrance may create a color representation of the image for which the evaluator wants to change the scent. Good.

<Ninth stage>
It is preferable that the scent development method of the present invention includes a ninth step of repeating the fourth step to the eighth step to determine a scent having a high degree of conformity to directionality.

<Step of confirming similarity between color representation diagrams>
The scent development method of the present invention preferably includes the step of confirming the similarity between at least two color representation diagrams.
The color representation diagram used in the image similarity evaluation method may be the color representation diagram of the same type of image or the color representation diagram of different types of images.
For example, the color representation diagram of the scent image of the first odor material and the color representation diagram of the scent image of the second odor material can be used to evaluate the similarity between the two images. After evaluating the first odor material, when evaluating the second odor material with the scent fine-tuned from the first odor material according to the wishes of the evaluator, the subtle difference in scent is used as the image similarity. Can be expressed.
Also, the similarity between the two images can be evaluated using the color representation diagram of the scent image of the first odor material and the color representation diagram of the character (word) image relating to the scent. Here, the images of characters (words) also vary depending on the person. In the image similarity evaluation method, for example, the scent image is changed into a color representation diagram, the character image is converted into a color representation diagram, and the scents are expressed in characters (words) by comparing in the same color representation diagram state. Rather than expressing it directly, it can be expressed objectively with image characters (words) of the scent. The letters or words used in this case are not particularly limited. It may be expressed in Japanese using characters such as hiragana, katakana, kanji, and alphabets, or may be expressed in a foreign language using characters used in a foreign language (for example, use Korean to express in Korean). Such).

At the stage of confirming the similarity between the color representation diagrams, the color representation diagram is a color arrangement table in which each color is arranged in the same arrangement as the color chart group;
When the part corresponding to each color of the color arrangement table includes a color palette;
It is preferable to judge the similarity between the color representation diagrams based on at least one of the following (C1) to (C4).
(C1) A correlation coefficient or a pattern similarity rate using the sum of values corresponding to the contribution rate of each color in the color palette or the value obtained by converting the sum of values corresponding to the contribution rate of each color into a ratio.
(C2) Correlation coefficient or pattern similarity rate using the number of steps determined by converting the sum of the values corresponding to the contribution rates of each color of the color palette into a ratio and normalizing it for each predetermined range of the ratio.
(C3) Numerical value of lightness and / or saturation of each color representation diagram calculated from a value obtained by converting the sum of values corresponding to the contribution rate of each color of the color palette or the sum of values corresponding to the contribution rate of each color to a ratio Size of
(C4) Correlation coefficient using the sum of values corresponding to the contribution rate for each hue and / or tone of the color palette, or the value obtained by converting the sum of the values corresponding to the contribution rate for each hue and / or tone to a ratio Or pattern similarity rate.

If "the sum of the values corresponding to the contribution rate of each color expressed by the color palette or the value obtained by converting the sum of the values corresponding to the contribution rate of each color to a ratio" is known, the similarity between the color representation diagrams can be calculated as " (C1) Correlation coefficient using the sum of the values corresponding to the contribution rate of each color represented by the color palette or the value of the sum of the values corresponding to the contribution rate of each color converted into a ratio or the pattern similarity rate " Preferably.
On the other hand, if you do not know "the sum of the values corresponding to the contribution rate of each color represented by the color palette or the value obtained by converting the sum of the values corresponding to the contribution rate of each color into a ratio", you cannot find the similarity between the color representation diagrams. , "(C2) Correlation coefficient or pattern similarity rate using the number of steps determined by converting the sum of the values corresponding to the contribution rates of each color of the color palette into a ratio and normalizing it for each predetermined range of the ratio". It is preferable to make a judgment based on this. In this case, from the "(C2) number of steps determined by converting the sum of the values corresponding to the contribution rates of the colors of the color palette into a ratio and standardizing the ratio in a predetermined range", "each color represented by the color palette The range of the pattern similarity rate, which will be described later, may be obtained by back-calculating the range of “the sum of the values corresponding to the contribution rate of or the value obtained by converting the sum of the values corresponding to the contribution rates of the respective colors into the ratio”.

Even if the color representation diagram is a petal diagram, if "the sum of the values corresponding to the contribution rate of each color represented by the color palette or the value obtained by converting the sum of the values corresponding to the contribution rates of each color to a ratio" is unknown In the same manner as the above, the range of "the sum of the values corresponding to the contribution rate of each color represented by the color palette or the value of the sum of the values corresponding to the contribution rate of each color converted to a ratio" is calculated backward from the number of steps in the color palette of the petal diagram. Then, the range of the pattern similarity rate described later may be obtained.

The correlation coefficient can be obtained by a known method. For example, the correlation coefficient R (or R ² ) can be obtained by the least square method or the function of spreadsheet software using the average value and the standard deviation of the contribution rates for each color chart. Instead of the contribution rate for each color chart, the sum of contribution rates for each hue, the sum of contribution rates for each tone, the sum of both the contribution rate for each hue and the contribution rate for each tone may be used. The closer the correlation coefficient R is to 1, the more similar it can be evaluated.
The pattern similarity rate is, for example, “Pattern similarity rate and its application-Pattern analysis in food research”, Shinhachiro Tamura, Tadanao Suzuki, Takashi Matsunaga, Nippon Shokuhin Kogyo Gakkai Vol. 32, No. It can be determined by the following method described in 11, 847-856 (1985).

(Pattern similarity measurement method)
Two numerical value group patterns A; (a ₁ , a ₂ , ..., A _n ) and patterns B; (b ₁ , b ₂ , ..., B _n ) consisting of the numerical values of n measurement items are provided. Having the same pattern means
_{_{_{_{a 1: a 2: ···:}}}} a n = b 1: b 2: ···: b n
Means
Therefore, the position vector of the n-dimensional space whose origin is O for each of the numerical group A and the numerical group B

If you think of the component display of

And vector

It is clear that the directions (including the directions) and are the same.
If the numerical value group patterns A and B match, vector

If the directions of and match and the pattern difference becomes large,

It is considered that the angle θ formed by and becomes large. Therefore,

By using the angle θ formed by or the function thereof, the similarity or heterogeneity of the pattern can be calculated as a numerical value. The pattern similarity is indicated by cos θ.
The pattern similarity between the pattern A; (a ₁ , a ₂ , ..., _An ) and the pattern B; (b ₁ , b ₂ , ..., b _n ) is S _{(A, B)} . Let's write. Vector dot product formula

From

Becomes
When the patterns are the same, θ = 0. Therefore, the pattern similarity in this case is S _{(A, B)} = COS0 ° = 1.
Further, if A and B do not include any common component, θ = 90 °. Therefore, the pattern similarity in this case is S _{(A, B)} = COS 90 ° = 0. The pattern similarity rate is a value between 1 and 0, and the closer the patterns are, the closer the value is to 1, for example, 0.999, which is intuitively easy to understand.

If the pattern similarity rate cos θ is more than 0.3 and 0.5 or less, it can be determined that the pattern similarity is slightly similar. You can judge that they are very similar.

[Color determination method]
The color determination method of the present invention corresponds to the direction included in the color expression diagram of the scent having a high degree of agreement with the direction determined by the scent development method of the present invention. The color of the fragrance with a high degree of fragrance, the flavor added with the flavor with a high degree of conformity with the determined direction, or the color of the fragrance or the packaging of the fragrance is determined.
According to the present invention, it is possible to provide a method for determining a color that corresponds to a color included in a color representation diagram of a scent that has a high degree of conformity to the directionality determined by the scent development method of the present invention.
For example, by using the colors included in the color representation diagram of the scent that has a high degree of agreement with the determined directionality, the color of the packaging of perfumes such as cosmetics (perfumes, shampoos, body soaps) and foods is determined. can do.

The present invention will be described more specifically below with reference to examples and comparative examples. The materials, usage amounts, ratios, processing contents, processing procedures, and the like shown in the following examples can be appropriately changed without departing from the spirit of the present invention. Therefore, the scope of the present invention should not be limitedly interpreted by the following specific examples.

[Example 1]: Development of fragrance of "adult-like" lemon flavored beverage <Direction visualization stage>
(The stage of visualizing the keywords other than the flavor by expressing them in a color diagram)
Regarding the existing lemon-flavored beverages that are the target of scent development, the word "adult-like" was set as the direction of the scent to be developed (direction of improvement of existing products). "Adult-like" is a keyword other than the flavor that is not related to the flavor of the lemon flavored beverage.
First, a step of expressing and visualizing the word "adultish" by using a method including the first step to the third step in a color representation diagram was performed. At the same time, the word "lemon", which is the word for the flavor of existing products, was visualized using a color diagram. Specifically, a color expression diagram was created by the following method.

-Color chart-
It was selected from the color system called PCCS, which was developed by the Japan Color Research Institute, mainly for color harmony. Six kinds of hues (red, orange, yellow, green, blue, purple), five kinds of tones (color tone; complex concept of lightness and saturation), 30 colors of achromatic colors, 6 colors of achromatic colors, and a third system (metal). Thirty-eight colors including gold and silver, which are the colors, were selected. By adopting PCCS and arranging selected colors on a two-dimensional array of hues and tones, it becomes easy to compare images by the arrangement of colors, and it becomes easy to capture the characteristics of images.
As the first system, a = 6 types of hues (red, orange, yellow, green, blue, violet), and as the second system, b = 5 types of tones (pale, light, vivid (). vivid), deep (deep), dark (dark), and 30 types of color charts, and as the third system, c = 6 types of achromatic colors (white, 4 levels of gray, black) and c = 2 types. A total of 38 types of color charts, each consisting of metal color (gold and silver) color charts, were prepared. Achromatic and metallic colors are also arranged on the two-dimensional array of hue and tone. This makes it easier to compare images by the arrangement of colors, and makes it easier to capture scent characteristics. The first system and the second system are formally determined. If necessary, the color expression diagram may be created with the tone as the first system and the hue as the second system.
A schematic view of the color patch group used in Example 1 is shown in FIG. In FIG. 1, each color chart is numbered.
In Figure 1,
11, 21, 31, 41 and 51 are color charts corresponding to pale, light, vivid, deep and dark when the hue is red;
12, 22, 32, 42 and 52 are color charts corresponding to pale, light, vivid, deep and dark when the hue is orange;
13, 23, 33, 43 and 53 are color charts corresponding to pale, light, vivid, deep and dark when the hue is yellow;
14, 24, 34, 44 and 54 are color charts corresponding to pale, light, vivid, deep and dark when the hue is green;
15, 25, 35, 45 and 55 are color charts corresponding to pale, light, vivid, deep and dark when the hue is blue;
16, 26, 36, 46 and 56 are color charts corresponding to pale, light, vivid, deep and dark when the hue is purple;
61 to 66 are color charts corresponding to white in the case of an achromatic color, gray in four steps, and black;

Reference numerals

71 and 72 are color charts corresponding to gold and silver when they are metallic colors.

-First stage-
As subjects, n = 17 persons were selected, and two colors were selected by each subject.
The color chart group shown in FIG. 1 is shown to one subject, and s = 2 types of color charts and their contribution ratios p ₁ and p ₂ (Unit:%) was selected from the color chart group.

-Second stage-
Based on the color chart selected by one subject and the contribution rate thereof, a pivot table having 38 columns corresponding to 38 types of color chart groups is created, and the values corresponding to the contribution rate of each color are set in the respective columns. I asked for. In each example, the value (unit:%) of the selected contribution rate of each color chart was used as it is as the value corresponding to the contribution rate of each color.

-Third stage-
The first stage was similarly performed for the remaining 16 subjects.
As a second step, a pivot table having 38 columns corresponding to 38 kinds of color chart groups was prepared for all the subjects, and the total of the selected contribution rates of the respective color charts was obtained in each column.
The sum of the values corresponding to the contribution rates of the respective colors on the obtained pivot table was divided by the sum of the contribution rates of all the subjects (17 subjects × 100% = 1000) and converted into the selection ratio of each color chart.

-Creation of color representation of petal diagram-
It is a petal diagram which has a polygonal core part of a polygon more than a polygon which has the side corresponding to the type a of the 1st system of a color chart group, and is on each side corresponding to the type a of the 1st system of a polygon. Color palettes of all colors belonging to the first system are arranged in a substantially parallel direction; the steps of each color palette are stacked and arranged toward the extension line of the radiation from the inside of the core part. A color expression diagram is created in which the number of steps of the color palette of each color is the number of steps determined by converting the sum of the values corresponding to the contribution rates of the respective colors into a ratio and standardizing it in a predetermined range of the ratio.
First, the number of stages in the color palette of the petal diagram was determined from the selection ratio of each color obtained by the analysis using the pivot table. In this embodiment, the number of stages is divided every 5%, 0% is 0 stage, 0% or more and less than 5% is 1 stage, 5% or more and less than 10% is 2 stages, 10% or more and less than 15% is 3 stages, 15%. More than 20% and less than 20% were 4 steps, and 20% or more were 5 steps.
Next, the selected color was divided into a = 6 types of hues and a total of 8 types of achromatic colors and metallic colors. Then, the core portion of the petal diagram was formed into a regular octagon, and the eight sides of the regular octagon were assigned to each one type of hue (total of 6 sides), achromatic color (1 side) and metal color (1 side).
Color palettes of all colors belonging to each hue, achromatic color, and metallic color are expressed in the order in which the tones are dark in the directions parallel to the eight sides of the regular octagon.
FIG. 2 shows a color expression diagram which is a petal diagram relating to the images of the words “lemon” and “adultish”. In Fig. 2, from the upper side of the paper, in the counterclockwise direction, stack each color pallet in the order of achromatic color, red, orange (left side of the paper), yellow, green (lower side of the paper), blue, purple (right side of the paper), metal color. is there. The same order applies to petal diagrams in which the other core portions are octagonal.

-Temporary creation of average color representation diagram, evaluation of color representation diagram-
An average color representation diagram was created from the "lemon" and "adultish" color representation diagrams (a concrete color representation diagram is not shown in FIG. 2). Specifically, the sum of the values corresponding to the contribution rate of each color at the time of creating each color representation diagram is further summed between the color representation diagrams of the "lemon" and "adultish" keywords, and the number of keywords ( A color expression diagram was provisionally created from the average value divided by 2) (or the average value converted into a ratio). The tentatively created average color representation diagram may be used as a visualization by expressing the directionality of the scent to be developed in the color representation diagram.
On the other hand, from FIG. 2, it was found that a dark color tends to be selected from the letters “adultish” and light yellow and green tend to be selected from the letters “lemon”. Moreover, the pattern similarity between the "lemon" color representation and the "adult-like" color representation was considered to be low.
Therefore, in this embodiment, without using the average color expression diagram of lemon and adult, in the present embodiment, “the step of visualizing a plurality of flavor-related keywords by expressing them in a color expression diagram” and “colors of a plurality of flavor-related keywords” Based on the similarity between the expression diagram and the color expression diagram of the non-flavor keywords, the step of ranking the similarity degrees of the flavor-related keywords to the non-flavor keywords "was performed.

(The step of visualizing multiple flavor-related keywords by expressing them in a color diagram)
The flavor-related keywords related to the flavor of lemon-flavored beverages, such as “sweetness”, “fruit juice”, “freshness”, “peel”, and “bitterness”, are the same as “adult-like”. Using the method including the first step to the third step, the step of expressing and visualizing with a color expression diagram was performed. Figure 3 shows a color expression diagram of "adult-like", which is a keyword other than flavor, and "sweetness,""juice,""freshness,""peel," and "bitter" that are flavor-related keywords. Indicated.
Here, as shown in FIG. 2, since the dark color tends to be selected from the word “adultish”, it is considered that the flavor-related keywords having many dark colors are important in the color expression diagram. Therefore, the words on the right side of the paper in FIG. 3 were expected to have a flavor that could express "adultish".

(A step of ranking the similarities of the flavor-related keywords to the non-flavor keywords based on the similarity between the color representation diagrams of the flavor-related keywords and the color representation diagrams of the non-flavor keywords)
Of the flavor-related keywords "sweetness", "fruit juice", "freshness", "peeling" and "bitterness", the color expression diagram and the keywords other than flavor "adult-like" The similarity with the color representation diagram was judged using the following criteria (C3).
(C3) Numerical value of lightness and / or saturation of each color representation diagram calculated from a value obtained by converting the sum of values corresponding to the contribution rate of each color of the color palette or the sum of values corresponding to the contribution rate of each color to a ratio Size of
Specifically, the lightness and saturation of the color representation diagram are obtained (values are omitted), and the similarity between the color representation diagram of flavor-related keywords and the color representation diagram of non-flavor keywords is determined from the values of lightness and saturation. did. As a result, the most "adultish" lightness and saturation values were low, and the lightness and saturation values were lower for the color representation diagram of the words on the right side of the paper in FIG. Therefore, it was found that the words on the right side of the paper in FIG. 3 have a higher order of similarity with the color expression diagram of “adult”.

<Candidate scent visualization stage>
A lemon-flavored beverage was prepared by adding flavors A, B and C as flavors to the existing lemon-flavored beverage.
The images of the lemon flavored beverages to which each flavor was added were visualized by expressing them in a color representation diagram. Specifically, in creating an "adult-like" color expression diagram, instead of the image of the word "adult-like" seen by the subject, the lemon flavor imparted with the three types of flavors that the subject tasted was added. A color expression diagram was created in the same manner except that two types of color charts that match the image of the flavor of the beverage and their contribution rates were selected. It is also possible to apply a certain amount of each fragrance to a predetermined odor evaluation paper piece to create a color expression diagram of the scent of the fragrance.
FIG. 4 shows a color expression diagram of the flavor of the lemon flavored beverage to which the flavor A, flavor B and flavor C are respectively added.
Furthermore, for each of the three types of color representations obtained, the value of each lightness and saturation converted into the ratio of the sum of the values corresponding to the contribution rate of each color in the color palette or the sum of the values corresponding to the contribution rate of each color The lightness and the saturation are shown in FIG. From the lightness and saturation values in FIG. 4, it was found that the color representation diagram of the flavor of the lemon-flavored beverage to which the flavor was added on the right side of the paper in FIG. 4 has lower lightness and lower again. Further, the "adult-like" color representation diagram had lower lightness and saturation values than the color representation diagram shown in FIG. Therefore, it was found that the color representation diagram of the flavor of the lemon-flavored beverage to which the fragrance was added on the right side of the paper in FIG. 4 had a higher similarity to the "adult-like" color representation diagram.

(Confirmation of agreement with sensory evaluation)
When the subject tastes the flavor of the lemon flavored beverage to which each of the flavor A, flavor B and flavor C has been added, the sensory sense is based on the applicability to the keyword "adult-like" other than the flavor for the candidate flavor. An evaluation was made. In the sensory evaluation, the subject was made to perform a sensory evaluation on an "adultish" sensation to obtain sensory evaluation data. In terms of scoring, a scale bar with 0 points on the left end (none), 1 point in the center (similar interval to existing lemon flavored beverages for fragrance development), and 2 points on the right end (very strong) is used. , I recorded one position that seems to be applicable on the scale. The score of each degree of sensation was the distance from the left end of the scale.
Furthermore, sensory evaluations were performed on the flavors of the lemon flavored beverages to which the flavors A, B, and C, which are candidate scents, were added, based on the applicability to flavor-related keywords. Specifically, sensory evaluations were similarly performed on the sensations of “sour taste”, “sweetness”, “juice feeling”, “fresh feeling”, “peel feeling” and “bitter feeling”.
The results of the sensory evaluation obtained are shown in Table 1 below. In addition, in FIG. 3, five kinds of flavor-related keywords in order from the left side of the paper surface to the right side of the paper surface are arranged from the lower side of the paper side to the upper side of the paper side in Table 1 below. Further, in Table 1 below, “sour taste”, which is a flavor-related keyword not shown in FIG. 3, is described on the bottom side.

From Table 1 above, focusing on the vertical row of lemon flavored beverages to which flavor B or flavor C was added, the keywords other than the “adult-like” flavor were strongly felt in the sensory evaluation. The tendency that the feeling of related keywords was strongly felt by sensory evaluation was read. Here, five kinds of flavor-related keywords in order from the left side of the paper surface to the right side of the paper surface of FIG. Therefore, it was also confirmed that the flavor-related keywords on the right side of the paper in FIG. 3 have a higher rank of keywords other than flavors.

<Selection stage>
The words on the right side of the paper in FIG. 3 have a higher order of image similarity with “adult-like”, and the sensory evaluation of “bitterness” of the lemon flavored beverage to which flavor A, flavor B or flavor C is added. From the results, the score of "bitter feeling" is 1.6 than that of the fragrance A in which the keyword "bitter feeling", which is a flavor-related keyword having a high image similarity to "adult-like", is 1.4. It can be selected that certain fragrances B and C are fragrance candidates that are highly relevant to the keywords other than the flavor "adult-like".
Alternatively, the words on the right side of the paper in FIG. 3 have a higher order of image similarity with “adult-like”, and the “sweetness” of the lemon-flavored beverage to which flavor A, flavor B or flavor C is added. From the results of the evaluation, the flavor-related keywords having a low image similarity with "adult-like", "sweetness", have a score of "1.1" or "1.0" than the flavors A and B. It can be selected that the flavors B and C having the score of “sweetness” of 0.8 are the flavor candidates having a higher relevance to the keywords other than the flavor of “adult”.
Furthermore, by combining the above two selections, it is possible to select that the fragrance C is the most suitable fragrance candidate for a keyword other than the flavor that is "adult-like".
Until now, it was common to express the validity of the flavor for the image based on the above sensory evaluation results, but by using the flavor expression method using colors, the sensory evaluation results can be obtained. Can be verified or visualized. In other words, since the flavor can be grasped from both sides of the word (sensory evaluation) and the color, a deeper consideration of the flavor becomes possible.
Specifically, as shown in FIG. 3, in the image of the color "adult-like", the lightness is dark as a whole or the color of a dark tone is often selected. FIG. 3 shows the result of arranging the color images of flavor-related keywords in order of lightness. It can be seen that for the three keywords on the right side of the paper surface of FIG. 3, dark tone colors are selected, and the hues of yellow, green, and blue are central. In other words, when the flavor of the "adult-like" lemon-flavored beverage is captured with a color image, it is presumed that the colors are dark tones and the hues of yellow, green, and blue are the main. Therefore, comparing the fragrances A to C, it is clear that the fragrance C has the lowest lightness and the selection ratio of yellow, green, and blue is higher than that of the fragrance A or B.
Therefore, it can be confirmed from the color image that the lemon-flavored beverage to which the flavor C is added has the most "adult-like" flavor among the three. That is, the selection step in the present invention proves that the validity of the sensory evaluation results (words) can be verified and visualized from the expression in a color image that does not use words, and the objectivity of the sensory evaluation results can be ensured. It was

Note that the selection step may be performed using only the keywords other than the flavor without using the flavor-related keywords. The direction of the scent to be developed will be the "adult-like" color expression diagram itself, which is the direction of the scent to be developed. If expressed in an abstract manner, the direction of the scent to be developed is set as the difference between the existing product and the improved product.
In fact, from Table 1 above, the lemon flavored beverages on the right side of the paper in Table 1 have a higher sensory evaluation score of “adult-like”, which is a keyword other than flavor, and have a higher relevance to keywords other than flavor. It is also supported by the order.
In the selection stage in this case, as shown in FIG. 4, based on the fact that the flavor of the lemon flavored beverage on the right side of the paper is more similar to the image of “adult-like”, the flavor C Together with the color representation diagram (the color representation diagram of the flavor of the lemon flavored beverage to which the fragrance C is added) is selected as a scent having a high degree of agreement with the "adult-like" direction. At that time, it can be selected together with the fact that the fragrance C has the highest sensory evaluation score of “adult-like”, which is a keyword other than flavor, and that it has high relevance to a keyword other than flavor. .
However, it is preferable to use the flavor-related keywords rather than only the keywords other than the flavor, from the viewpoint of easy selection of candidate scents and fragrance preparation.

[Example 2]: Development of scent of tea-flavored beverage "to enhance nostalgia compared to existing products"<Direction visualization stage>
(The stage of determining the directionality of the scent to be developed)
A questionnaire was conducted as a consumer survey on existing black tea flavored beverages (commercial lemon tea A and B) as indexes. From the results, the direction of improvement of the existing black tea flavored beverage (another commercially available lemon tea C) whose aroma was developed was determined. Specifically, in the consumer survey, it was found that the commercial lemon tea A was more nostalgic than the commercial lemon tea B, so the direction of improvement of existing tea flavored beverages (product concept ), We decided to aim for a tea-flavored beverage that “makes us more nostalgic than existing products”. Note that “nostalgia” is a keyword other than the flavor that is not related to the flavor of the tea-flavored beverage.

(The stage of visualizing the keywords other than the flavor by expressing them in a color diagram)
The word "nostalgia" was expressed in a color expression diagram and visualized by the method according to Example 1, and a color expression diagram of "nostalgia" was created.
However, the direction of the scent to be developed was not set to the color expression diagram of "nostalgia".

(The step of visualizing the flavor of the existing product as an index by using a color expression diagram, and checking the degree of agreement with the sensory evaluation)
The flavor expression of the commercial lemon tea A and the commercial lemon tea B is represented by a color expression diagram and visualized by the method according to Example 1, and the color expression of the flavor of the commercial lemon tea A and the commercial lemon tea B is performed. I made a diagram. FIG. 5 shows a color expression diagram of “nostalgia”, “flavor of commercial lemon tea A”, and “flavor of commercial lemon tea B”. The similarity of the color representations between "nostalgia" and "flavor of lemon tea A on the market" is more similar to that between "nostalgia" and "flavor of lemon tea B on the market". It was confirmed by the method described herein that it is higher than the similarity of the color diagram.
In addition, when the subject tastes the flavors of the commercially available lemon tea A and the commercially available lemon tea B, the sensory evaluation based on the applicability to the keyword “nostalgia” other than the flavor is performed in the same manner as in Example 1. I went there. As a result, it was found that the sensory evaluation score of nostalgia was actually higher in the commercial lemon tea A than in the commercial lemon tea B.

(The step of visualizing multiple flavor-related keywords by expressing them in a color diagram)
Of the flavor-related keywords related to the flavor of tea-flavored beverages, "refreshing", "refreshing", "sweetness", "afterglow", "koku", "rich feeling", "tea leaf feeling", "astringency" In the method according to Example 1, the words were expressed in a color expression diagram and visualized. FIG. 6 shows a color expression diagram of "nostalgia" which is a keyword other than flavor and each flavor-related keyword.

(A step of ranking the similarities of the flavor-related keywords to the non-flavor keywords based on the similarity between the color representation diagrams of the flavor-related keywords and the color representation diagrams of the non-flavor keywords)
Similar to the first embodiment, the non-flavor keywords of the plurality of flavor-related keywords are based on the similarity between the color representation diagram of the plurality of flavor-related keywords and the color representation diagram of the non-flavor keywords based on the values of lightness and saturation. Then, the step of ranking the degree of similarity to was performed. As a result, it was found that the words on the right side of the paper in FIG. 6 were in a rank in which the similarity to the color expression diagram of “nostalgia” was higher.

(A step of expressing the direction of the scent to be developed with a color expression diagram)
The flavor of commercially available lemon tea C, which is the target of scent development, was expressed and visualized by a method similar to that of Example 1 to create a color expression diagram of the flavor of commercially available lemon tea C. .. A color representation of the flavor of commercially available lemon tea C is shown in the lower left of the page of FIG.
The difference between the color nomenclature of "nostalgia" and the flavor of the commercial lemon tea C was calculated. Specifically, the value corresponding to the contribution ratio of each color is calculated for each hue (in FIG. 7, counterclockwise from the upper side of the drawing, achromatic colors, red, orange (left side of the drawing), yellow, green (lower side of the drawing), Differences were calculated for each hue of both color representation diagrams with respect to the sum of values for blue, purple (on the right side of the paper, and hues in the order of metal color). As a result, it was determined that the hue lacking due to nostalgia from the commercially available lemon tea C was "orange" or "red".
First, of the flavor-related keywords shown in FIG. 6, “tea leaf feeling” having a high orange hue was selected. Then, an average color expression diagram of the color expression diagram of the flavor of commercially available lemon tea C and the color expression diagram of “tea leaf feeling” is created, and the obtained average color expression diagram is used for the first developed fragrance. It was directional. The obtained average color representation diagram is shown in FIG. 7 as a color representation diagram of “Orange Image UP”.
Next, of the flavor-related keywords shown in FIG. 6, “sweetness” having a high red hue was selected. Then, an average color expression diagram of the commercially available lemon tea C color expression diagram and the "sweetness" color expression diagram is created, and the obtained average color expression diagram is used for the second developed fragrance. It was directional. The obtained average color representation diagram is shown in FIG. 7 as a color representation diagram of “red image UP”.

<Candidate scent visualization stage>
A black tea flavored beverage was prepared by adding flavor 1 and flavor 2 as flavors to commercially available lemon tea C, respectively.
The images of the tea flavored beverages to which each flavor was added were visualized by expressing them in a color representation diagram (details of the obtained color representation diagram are omitted).

<Selection stage>
The tea flavored beverage to which the flavor 1 was added had a high similarity to the color expression diagram of “Orange Image UP” in FIG. 7. Therefore, the fragrance 1 can be selected as a scent candidate having a high degree of agreement with the directionality of the first scent to be developed.
The tea flavored beverage to which the fragrance 2 was added had a high similarity to the color expression diagram of “red image UP” in FIG. 7. Therefore, the fragrance 2 can be selected as a scent candidate having a high degree of agreement with the directionality of the second scent to be developed.

(Confirmation of agreement with sensory evaluation)
For the commercially available lemon tea C, the tea flavored beverage with the flavor 1 added, and the tea flavored beverage with the flavor 2 added as the flavor, sensory evaluation was performed based on the relevance to the keyword “nostalgia” other than the flavor. It was As a result, the score of "nostalgia" was 0.8 for the commercially available lemon tea C, which is an existing product, whereas 0.8 was for the tea flavored beverage to which the flavor 1 was added as a flavor, and 2 for the flavor. The tea-flavored beverage provided was 1.3. The obtained results are shown in FIG. 7.
Therefore, since the black tea flavored beverage to which the fragrance 2 is added has a higher sensory evaluation score of “nostalgia” than the tea flavored beverage to which the fragrance 1 is added, the color representation diagram of the “red image UP” in FIG. Was highly similar to. Therefore, the fragrance 1 can be selected as a scent candidate having a higher degree of agreement with the directionality of the scent to be developed.

[Example 3]: An example of developing an average color expression diagram of a plurality of keywords as a scent direction <direction visualization stage>
We developed a scent when the product concept was not narrowed down when the scent was developed for a new shampoo product.
First of all, the keywords “family-friendly”, “friendly”, “creamy”, “moisturizing”, “feeling of peace”, “powdery” and “baby powder”, which are keywords included in the product concept, are described in Example 1. Each of them was represented by a color representation diagram according to a similar method.
Next, an average color representation diagram was created from each of the obtained color representation diagrams of the plurality of keywords, and the average color representation diagram was used as the product concept (direction of the scent to be developed).
FIG. 8 shows a color expression diagram of each of a plurality of keywords included in the product concept and a color expression diagram of the directionality (product concept) of the scent to be developed, which is the average of them.

<Candidate scent visualization stage>
With reference to the color expression diagram of the product concept shown in FIG. 8, a new fragrance was added. Among the newly-perfume candidate fragrances, the fragrance a was visualized by expressing it in a color expression diagram. FIG. 9 shows a color expression diagram of the product concept shown in FIG. 8 and a color expression diagram of the fragrance a.

<Selection stage>
The fragrance a, which is a candidate fragrance, can be selected as a fragrance having a high degree of conformity to the directionality (product concept) together with a color expression diagram in which the fragrance of the fragrance a is visualized.
Here, of the candidate scents, the fragrance a had the highest degree of agreement with the directionality of the scent developed by the color expression diagram. This confirmed the similarity between the color representation of the product concept and the color representation of the candidate scents (perfume a etc.) by the method described herein.
Therefore, by comparing the two color representation diagrams, it is possible to evaluate the degree of matching of the candidate scent with the product concept. As a result, it is possible to select a fragrance having a high degree of agreement with the product concept.

According to the present invention, the characteristic of the directionality of the scent to be developed can be represented by a color representation diagram. Since the information of the color representation diagram is information that can be easily transmitted, managed and stored, it is possible to compare the characteristics of a plurality of images.
The present invention, particularly in the development of products using fragrances or flavors, shares the evaluation of the image of the direction of the scent to be developed by the product, can be used bidirectionally in changing the image, a package design suitable for this, It can also be used for color selection and color arrangement when creating advertisements.
