Abstract

PURPOSE:To qualitatively select masking perfume with ease by using similarity and magnitude ratio of the two vectors, a smell to be masked and the smell of the masking perfume similar to the former, as indices. CONSTITUTION:A smell to be masked and the undesirable smell in masking perfume (smell similar to the smell to be masked) are represented by vectors on the same coordinate system, and similarity in respective vectors' orientation (sine of vector's intersection angle) and the ratio in magnitudes of two vectors (vector ratio) are obtained. The two vectors use profiles of, for example, 15 items, such as material smell and a similar smell as the smell to be masked in the masking perfume. When selecting a coordinate axis of smell as an index for selecting masking perfume, selection is made so that similarity degree becomes 0.5-1 and vector ratio 0.5 or more. If masking method by perfume is theorized as this, perfume is easily selected and very useful for addition of smell to cosmetic material and processed foods.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a method for qualitatively selecting masking fragrances.

[0002]

2. Description of the Related Art In cosmetics such as creams and milky lotions, and processed foods such as ice cream and chocolate, it has been long practiced to improve the aroma and flavor by using fragrances such as fragrances and flavors. This is based on the idea that the odor of raw materials used for cosmetics and processed foods impairs the image of the product, and therefore flavors are added to these cosmetics and processed foods to mask the raw materials with the flavors. However, the types of fragrances to be used for masking with fragrances have been investigated so far only with empirical knowledge. In addition, the perfuming rate in this case was actually determined several times by changing the rate and repeating the perfuming, and observing the result.

As described above, the conventional masking method using a fragrance has no theoretical guideline and is actually carried out by trial and error based on experience.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method for qualitatively and easily selecting a masking fragrance based on theoretical guidelines.

[0005]

Means and Actions for Solving the Problems The present inventor has conducted earnest research based on a practical example of masking with a conventional fragrance, and as a result, found a causal relationship between the fragrance to be masked and the odor to be masked. Was completed.

More specifically, the present inventor expresses the masked odor (masked odor) as a vector consisting of simple odor elements (hereinafter referred to as masked odor vector), and is similar to this masked odor vector. Moreover, it was found that good masking can be performed by searching for a fragrance containing a vector having an appropriate size and masking the masked odor with the fragrance thus selected.

Therefore, in the method of selecting a masking fragrance of the present invention, the masked odor and the odor similar to the masked odor in the masking fragrance are represented by vectors, and the similarity and magnitude of these two vectors are determined. The fragrance is selected by using the ratio as an index.

The present invention will be described in detail below. Generally, in perfume, the scent as a whole is preferable to many people, but it is known that the scent has various elements. It is also known that some of these elements have a small amount of odor which is not desirable per se but rather belongs to the malodorous class. In other words, it is a well-known fact that the element of the scent close to the malodor is also an element necessary for producing a preferable scent.
This is because the presence of a preferable scent element that is present as a game element is emphasized (or emphasized) due to the presence of a trace amount of an unpleasant scent element that is close to a bad odor, and the element is strongly strengthened. Because it makes an impression. For example, the unpleasant scent as a shadow brings out the highlight scent, and the scent has a depth and three-dimensional effect.

In fact, for example, the musk odor, which is an unpleasant scent as an animal odor, can bring out a gorgeous scent of rose and the like and can maintain it. From these things,
It will be appreciated that the concept of the sum of the preferred scent vector and the unfavorable scent vector can be used when expressing a fragrance.

The present inventor focused on the above facts and analyzed various successful and unsuccessful examples of masking. As a result, the following causal relationship between the masked odor and the unpleasant scent in the fragrance was found. Found that there is.

That is, when the odor to be masked and the unpleasant scent in the fragrance (odor similar to the odor to be masked) are represented by vectors on the same coordinate, the degree of similarity in the direction of each vector (similarity: The sine of the intersection angle of the two vectors) and the magnitude ratio of the two vectors (vector ratio) are given by the following I if the respective vectors are a and b.
It can be obtained by the formula and the formula II.

[0012]

[Equation 1]

[0013]

[Equation 2]

In the above equation, ai is a profile score of a vector of an odor similar to the masked odor in the masking fragrance, bi is a profile score of the masked odor vector,
Further, θ represents the intersection angle of these two vectors.

This similarity is 0.5 to 1, preferably 0.
It was found that the desired masking can be performed when the ratio is 6 to 1 and the vector ratio is 0.5 or more, preferably 0.5 to 2.5.

When the masked odor and the unpleasant scent in the fragrance are expressed by vectors, it is necessary to set coordinate axes.
For that purpose, a normal sensory term may be used, and a normal sensory profile may be used for the magnitude of the vector. This is because these two vectors can be compared on the same coordinate.

The above two vectors are, for example, milky odor axis, smokey odor axis, oily odor axis, metallic odor axis, dust odor axis, musty odor axis, resin odor axis, wax odor axis. , The axis of fat odor, the axis of powder odor, the axis of soap odor, the axis of vegetable odor, the axis of aldehyde odor, the axis of chemical odor, and the axis of sweet odor. be able to.

In any case, as can be seen from the above description, when these odor coordinate axes are selected, the similarity is 0.
It is preferable to select 5 to 1 and a vector ratio of 0.5 or more.

On the other hand, as the fragrance for masking, all the conventional fragrance and fragrance fragrances can be used.
