Description

  The present invention can be used to add a very small amount of flavors such as bitterness, astringency and egg flavor of foods and beverages and pharmaceuticals, and flavors that are too strong as flavors of foods and beverages and oral pharmaceuticals, without changing the basic flavor balance. The present invention relates to a masking agent capable of masking.

The food and drink has a preferable basic flavor balance for each food and drink.
However, during food processing such as heat sterilization and preservative addition during the production of food and drink, and during the preservation period of the food and drink, flavors that disrupt the flavor balance, such as bitterness, astringency, or egg flavor, A miscellaneous taste may be generated.
In such a case, processing to remove those miscellaneous tastes, such as distillation or elution, may be performed, but such an operation is extremely complicated because it removes trace components, and even the basic flavor of food and drink There is a risk of reduction.

Moreover, in some foods and drinks, only a specific flavor is very strong, and the preferred basic flavor balance of the food and drinks may be lost.
In such a case, the food component having the specific flavor may not be blended or removed, but other flavors may be scraped off, further disrupting the flavor balance of the food and drink. Become.

  Therefore, foods and drinks having a miscellaneous taste can be made to feel the above-mentioned miscellaneous taste without greatly degrading the balance of the basic flavor of the food and drink, and there is only a specific flavor that is extremely strong. For this reason, various proposals have been made on so-called masking agents that can weaken a specific flavor that is too strong by adding a very small amount of components.

  For example, polyglycerin condensed ricinoleic acid ester (see, for example, Patent Document 1), stevia extract (see, for example, Patent Document 2), dried mysids, and / or krill extracts (see, for example, Patent Document 3), gluconic acid Non-toxic salts (see, for example, Patent Document 4) and the like have been proposed, but the masking agent of Patent Document 1 is an emulsifier and thus often affects physical properties, and the flavor itself is poor. There is a problem, the masking agent of Patent Document 2 is effective only for foods and drinks having a bitter taste and astringency, and there is a problem that the amount of addition is limited due to its strong sweetness, and the masking agent of Patent Document 3 In addition to being effective only for bitterness, there is a problem of requiring a relatively large amount of addition, and the masking agent of Patent Document 4 requires a relatively large amount of addition. There has been a problem to say.

JP 2002-65177 A JP 2005-336078 A JP-A-10-179077 WO00 / 48475

  Therefore, the object of the present invention is to mask the miscellaneous taste of foods and beverages and pharmaceuticals and the flavors that are too strong as the flavors of foods and beverages and pharmaceuticals with the addition of a very small amount without changing the basic flavor balance. A masking agent and a masking method are provided.

As a result of various investigations to achieve the above object, the present inventors, as a result of adding a very small amount of whey mineral obtained by a specific production method, to the above-mentioned miscellaneous taste and foods and beverages having a too strong flavor. Even if it exists, it discovered that a very strong masking effect was shown.
This invention is made | formed based on the said knowledge, and provides the masking agent which contains the whey mineral obtained through the following (a) (b) (c) processes as an active ingredient.
(A) A step of separating milk or whey from a demineralized liquid by membrane separation and / or ion exchange to obtain a high mineral liquid (I) (b) By heating the high mineral liquid (I), calcium -Step of separating and removing the phosphate complex to obtain a high mineral liquid (II) (c) Concentrating and / or drying the high mineral liquid (II) until the solid content is 20% by mass or more, and whey The process of obtaining a mineral Moreover, this invention provides the masking method of the miscellaneous taste of food-drinks, or the too strong flavor characterized by adding this masking agent to food-drinks or a pharmaceutical.

The masking agent of the present invention can mask miscellaneous tastes and excessively strong flavors contained in foods and drinks by adding a very small amount without changing the basic flavor.
According to the masking method of the present invention, it is possible to mask miscellaneous taste and excessively strong flavor contained in foods and drinks without changing the basic flavor.

First, the whey mineral used in the present invention will be described in detail.
