Description

  The present invention is a beverage that is improved in flavor, aging, mellowness, etc. by adding a taste improver obtained by concentrating an acetic acid fermentation product produced from a protein and a saccharide raw material, and It relates to the manufacturing method.

  Many seasoning ingredients have been used for the purpose of adjusting the flavor of beverages, such as sweeteners such as sucrose and fructose, acidulants such as citric acid and malic acid, and flavorings and thickening stabilizers. ing. Among these, flavors and thickening stabilizers, in particular, give flavor, aging, and mellowness to the flavor of beverages, and they vary depending on the physical properties and flavor characteristics of the beverage to be used. Are properly used.

  In perfume, it is added to fruit juice drinks, coffee drinks, sparkling liquor, etc. to enhance or supplement the scent inherent in the drinks, thereby making the drinks rich and mature, and highly drinkable Is used as a purpose. Further, the thickening stabilizer is used for the purpose of giving a rich feeling to drinks (thickness is not thick) including jelly drink, milk coffee, and other low calorie high intensity sweeteners.

  However, these fragrances and thickening stabilizers are recognized as substances that are newly added to foods, even in the case of naturally derived substances, so they are never good for consumer image and health orientation. It is also said that fragrances are easy to get bored by continuing to drink.

  In addition, vinegar beverages characterized by containing vinegar among the beverages are strongly stimulated by acidity and odor due to organic acids such as acetic acid, which is the main ingredient of vinegar, so if you try to add more vinegar, It has the disadvantage that the odor stands out and can not be easily taken. On the other hand, vinegared beverages are products that are highly demanded by consumers due to their health consciousness, so the development of methods for reducing their acidity and odor is required. However, many artificial sweeteners, fragrances, and the like have been devised as means for this. However, as mentioned above, these means do not match the consumer's image or health orientation.

JP 2006-147553 A Japanese Patent No. 3777002 JP 2006-94817 A JP 2001-069965 A

  From such a background, the present invention is a taste improver that can be easily imparted to a beverage without making the flavor rich and matured, mellowness, etc., unsuitable for the user's image or health orientation, And it aims at providing the drink containing a taste improving agent. Another object of the present invention is to provide a vinegar beverage that has a sour taste and aging feeling added to alleviate the sourness and odor peculiar to vinegar.

  As a result of intensive studies to solve the above-mentioned problems, the present inventors concentrated a fermentation product of acetic acid produced from a protein and a saccharide raw material to obtain a taste improver. It has been found that by concentrating an acetic acid fermented product produced from protein and saccharide raw materials, the acidity and odor of the acetic acid fermented product can be reduced. The present invention was completed by finding that it can be used as an imparting agent such as a feeling of aging, a feeling of aging, and mellowness.

  The present invention provides a taste improver obtained by concentrating an acetic acid fermented product and a beverage taste improving agent obtained by concentrating an acetic acid fermented product. Further, the fermented acetic acid may be a fermented liquid obtained by alcohol-fermenting a saccharide raw material and then acetic acid-fermenting.

  In addition, the present invention provides a fermented liquid obtained by subjecting a contained alcohol to acetic acid fermentation, or a fermented liquid obtained by subjecting a sugar material to alcohol fermentation and then acetic acid fermentation, or an amino acid-containing composition and a sugar material in an acetic acid fermentation process. It is a taste improving agent characterized in that it is produced by concentrating and producing vinegar obtained by adding and fermenting until the color tone changes, and after adding an acetic acid fermented product before concentration and after concentration For the acetic acid fermented product, when diluted with a diluting solution so that the absorbance at OD 420 nm is within the range of 0.001 to 0.500, the total liquid amount after dilution is divided by the arbitrary amount of the acetic acid fermented product. When the numerical value obtained by multiplying the dilution factor obtained by each absorbance value is the color intensity of the acetic acid fermented product, the change in the color tone of the acetic acid fermented product due to the concentration (the color strength of the liquid after concentration) ) / (Color of pre-concentration solution Degrees) = 1.1 to be a taste-improving agent having a color selected from a range of 50.

  This invention provides as a drink containing said taste improving agent. In addition, it is characterized by reducing acidity and / or odor by concentrating vinegars obtained by adding an amino acid-containing composition and a saccharide raw material in an acetic acid fermentation process and fermenting them until the color changes. It provides as a drink containing the taste improving agent. Moreover, you may make it the drink characterized by containing the density | concentration selected from the range of 2 weight% thru | or 90 weight% with respect to a drink.

  Concentration of the acetic acid fermented product mentioned here is considered to be difficult due to the concentration efficiency, and the numerical value with the change in color tone as an index is 50, and the concentration indicating a value higher than that is physically difficult to show the acetic acid fermented product. .

  Concentration of acetic acid fermented products that has been performed in the past is intended to reduce the acidity and improve the flavor of the acetic acid fermented product itself, or to avoid the stimulating sourness and acid smell derived from acetic acid in the acetic acid fermented product. The main purpose was to reduce the volume by reducing the proportion of the liquid component, such as by pulverizing and confining in a soft capsule or hard capsule. However, the purpose of concentration used in the taste improver of the present invention is to produce a seasoning material that gives a new flavor such as richness, aging, and mellowness to the beverage, based on the acetic acid fermentation product.

  The reason why the flavor of the beverage is improved by containing the taste improver of the present invention is considered as follows. In general, it is known that taste receptors that sense taste are present in taste buds composed of taste cells. The miso at the tip of the tongue is mainly sweet and salty, and the miso at the back of the tongue is mainly umami. The taste is felt not only on the tongue but also on the soft palate and the back of the throat, and the product of the present invention has a spatial spread in the flavor by making the taste feel at these multiple sites. Moreover, since the food and drink containing the product of the present invention has a flavor that spreads slowly afterwards and has a lingering taste, it can be said that the taste is stimulated in stages. It is considered that flavors such as “richness”, “ripening feeling”, and “mellowness” are imparted to the taste by a plurality of spatial and temporal effects.

  In general, flavors such as “richness”, “ripening”, and “mellowness” are considered to be one of the important factors in umami, and these are not the taste derived from a single substance, It is recognized that multiple tastes derived from countless substances contained are intertwined in a complex manner. Similarly, the “taste” of food and drink is perceived not only by taste but also by a plurality of factors such as smell and texture. In the present invention, by concentrating the acetic acid fermented product, the ratio of amino acids and organic acids contained is increased, and by containing those components in the beverage, a plurality of tastes and olfaction are stimulated and spread to the taste of the beverage We succeeded in having.

  In addition, vinegar and other concentrates are improved without adding artificial sweeteners or fragrances that may harm the user's health consciousness to vinegar beverages that are highly demanded by consumers due to their recent health-consciousness. It was made to act as an agent, soothing the sourness and odor peculiar to vinegar while maintaining the original taste and function of vinegar beverages, and succeeding in adding a rich flavor and aging.

  According to the present invention, by adding a taste improving agent obtained by concentrating an acetic acid fermented product to a beverage, flavors such as “thickness”, “ripening feeling”, and “mellowness” are imparted. That is, by using the taste improving agent of the present invention, taste adjustment can be performed on a beverage without disobeying the consumer's image or health orientation. In addition, the sourness and odor peculiar to vinegar can be relieved for a vinegar drink, and a rich and matured sensation can be added.

  The acetic acid fermented product as used in the present invention is made from grains such as rice, wheat, corn, millet, millet, amaranth, beans, and potatoes, and fruits and fruit juices such as apples, grapes, prunes, strawberries, and pineapples. Made using microorganisms. It is classified into the following 1 to 3 stages according to the mode of use of microorganisms.

  The one-stage type is a type in which the contained alcohol is changed to acetic acid by the action of acetic acid bacteria, and alcohol vinegar and straw vinegar correspond to this. The two-stage type is a type in which yeast is added to raw materials containing fermentable sugars (glucose, fructose, maltose, sucrose, etc.) to make alcohol, and then acetic acid bacteria are added to it to convert it into acetic acid. Molasses vinegar and fruit vinegar Belongs to this. The three-stage type is a type in which starch, cereals, and potatoes are decomposed into fermentable sugars using rice cakes and enzyme preparations, yeast is added to make alcohol, and then acetic acid bacteria are used to convert to acetic acid. Vinegar and malt vinegar belong to this.

About alcohol fermentation processing conditions, a conventionally well-known method can be utilized suitably. For example, the fermentation can be completed in 3-4 days with occasional stirring at 30 ° C. Useful yeasts include Saccharomyces
cerevisiae AKU4100, Saccharomyces sake AKU4111, Schizosaccharomyces pombe AKU4220, Saccharomycodes
Iudwigi AKU4400 or the like can be used.

For acetic acid fermentation conditions, a conventionally known method can be used as appropriate. For example, the fermentation can be completed in 24 to 48 hours with stirring at 30 ° C. under a deep fermentation method. Useful acetic acid bacteria include Acetobacter
acetobium IFO 3283, Acetobacter rancens IFO 3298, Acetobacter methanolicus JCM6891, Acetobacter
pasteurianus IFO 3222, Acetobacteraceti IFO 3299, Acetobacter lovaniensis SKU1108, etc. can be used.

  In the present invention, “concentration” refers to a process in which the volume after concentration is smaller than that before concentration. As a concentration method, a conventionally known method such as vacuum concentration, freeze concentration, membrane concentration or the like can be appropriately used. Concentration under reduced pressure is a method of reducing the boiling point of a solvent by reducing the pressure with an aspirator or a vacuum pump, thereby concentrating efficiently. Freeze concentration means that when a liquid material is frozen, only water molecules become ice. This is a method in which water as a solvent is separated as ice and concentrated. Membrane concentration is a method of increasing the solute concentration by allowing only the solvent to permeate through the pressure difference or temperature difference across the membrane as a driving force. Concentration time can be concentrated over a long period of time, but for example, a taste improver that exhibits the effects of the present invention can be obtained even in a short period of time such as 30 minutes to 5 hours. And its manufacturing method is also suitable for industrial production.

  In the present invention, the amino acid-containing composition refers to a single amino acid, amino acid sodium salt, protein and koji, fermented koji, protein hydrolyzate, yeast extract and the like containing a large amount thereof, and the saccharide raw materials are rice and wheat This refers to cereals such as corn, millet, millet, amaranth, beans, and cereals, and fruits or fruit juices such as apples, grapes, prunes, persimmons, and pineapples. In addition, the vinegar as referred to in the present invention is not defined by acidity (in terms of acetic acid) or soluble solids, but indicates general vinegar produced and adjusted for edible use, not only consisting of only acetic acid fermentation products, Includes blends of synthetic vinegar.

  The standard for concentrating the acetic acid fermented product and the measuring method will be described below. An arbitrary amount of the acetic acid fermented product before concentration and the same amount of the concentrated acetic acid fermented product are taken out and appropriately diluted with a diluent so that the absorbance at OD 420 nm is in the range of 0.001 to 0.500. At this time, the value obtained by multiplying the dilution ratio obtained by dividing the total liquid volume after dilution by the liquid volume of the first acetic acid fermentation product obtained by multiplying each absorbance value is the color of the acetic acid fermentation product. When the strength is considered, the change in color tone of the fermented acetic acid product due to concentration is (color strength of the solution after concentration) / (color strength of the solution before concentration) = 1.1 to 50, preferably 5 to 50, more preferably 10 It is desirable to concentrate so that it may become in the range of -50.

  In particular, when used by adding to mango juice, the above-mentioned color tone change is (color strength of the liquid after concentration) / (color strength of the liquid before concentration) = 1.1 to 50, preferably within the range of 5 to 50. It is desirable to concentrate so that it becomes.

  In addition, when used by adding to a milk beverage, the above-mentioned color tone change is (color strength of the liquid after concentration) / (color strength of the liquid before concentration) = 5-50, more preferably within the range of 10-50. It is desirable to concentrate so that it becomes.

  In addition, when used by adding to a sports drink, the aforementioned color tone change is (color strength of the liquid after concentration) / (color strength of the liquid before concentration) = 1.1 to 50, preferably within the range of 10 to 50 It is desirable to concentrate so that it becomes.

  In addition, when used by adding to a chuhai beverage, the above-mentioned color tone change is (color strength of the liquid after concentration) / (color strength of the liquid before concentration) = 1.1 to 50, preferably 10 to 50 It is desirable to concentrate so that it becomes.

  The absorbance at OD 420 nm referred to here was measured at room temperature using a commonly used spectrophotometer “U-1000 type spectrophotometer manufactured by Hitachi, Ltd.”. Here, the diluent is generally water.

  This change in color tone changes depending on the degree of reaction such as aminocarbonyl (Maillard) reaction. The aminocarbonyl reaction that normally occurs in foods in the presence of sugars and amino acids that are nitrogen components has been disliked as a phenomenon that changes the color of foods to brown and degrades the flavor. Therefore, a method that does not cause an aminocarbonyl reaction in the production process of food has been sought. However, the present inventor dared to pay attention to the aminocarbonyl reaction, and found that the presence of a reaction product of sugar and amino acid has an effect of improving the flavor of the beverage.

  This invention discovers that the acetic acid fermented product which promoted the aminocarbonyl reaction by concentrating has a taste improving effect, and makes it possible to improve the flavor of the beverage using this. The beverage here refers to all beverages and is not particularly limited. Not only general drinks including sugars, fruit juices, and fragrances, but also drinks using fermented milk, coffee, tea, tea, sports drinks, carbonated drinks, sparkling liquors, and alcoholic beverages can be used.

  Examples of the present invention will be described below.

  Liquefied enzyme was allowed to act on the brown rice and liquefied at 60 to 70 ° C. for 3 hours. Subsequently, a saccharification enzyme was added and saccharification was performed at 50-60 degreeC for 16 hours. Yeast was added to the obtained saccharified solution and alcohol fermentation was performed at 25 to 30 ° C. to obtain brown rice alcohol having an alcohol concentration of 15% and a sugar concentration of 1%. The obtained brown rice alcohol was inoculated with acetic acid bacteria and subjected to acetic acid fermentation at 25 to 30 ° C. After filtering the obtained acetic acid fermentation broth, it age | cure | ripened at 25-30 degreeC in the aging tank. After aging, filtration and sterilization were performed to obtain vinegar having a nitrogen concentration of 0.8%, a salt concentration of 0.05%, a sugar concentration of 15%, and an acidity of 8% (in terms of acetic acid). Furthermore, it concentrated with the vacuum concentration machine and obtained the taste improving agent of this invention.

  As a standard for concentration, the change in color of vinegars due to concentration was used. The color intensity after concentration (OD420 nm) / the color intensity before concentration (OD420 nm) was specified as a ratio value. Here, the change in color tone was measured by a commonly used absorbance measuring instrument “U-1000 Model Hitachi, Ltd.” Measurement was carried out using a spectrophotometer. The color change was measured at room temperature (18 ° C. to 30 ° C.) immediately after concentration.

  Moreover, the powder goods were manufactured as follows using the taste improving agent of this invention adjusted in Example 1. FIG. 20 kg of vinegar was concentrated to obtain a 10 kg concentrated product. Next, 3 kg of dextrin was added and spray drying was performed to obtain 5 kg of a powder product. Thus, the taste improving agent may be provided as a powder product, or the powder product may be added to a beverage to provide a beverage containing the taste improving agent.
