Abstract

Provided is a taste improver that improves or decreases unpleasant bitterness, astringent taste, harsh taste, bitter taste, or the like that results from potassium salts, magnesium salts, calcium salts, and ammonium salts without adversely affecting savoriness of a food or drink. The taste improver includes a vegetable extract and/or a phospholipid. In the taste improver, the aforementioned vegetable extract includes a vegetable-derived glycoside and/or glycoside aglycone. In the taste improver, the aforementioned phospholipid is phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine, phosphatidylinositol, and/or a lyso form thereof. Arginine is further added to the aforementioned taste improver. Trehalose and/or hydrogenated starch syrup are further added to the taste improver. A manufacturing method of such and an improvement method for the unpleasant bitterness, astringent taste, harsh taste, bitter taste, or the like caused by potassium salts, magnesium salts, calcium salts, and ammonium salts using these taste improvers. A food or drink including these taste improvers.

First claim

The invention claimed is:

1. A taste improvement method for a foodstuff comprising at least one salt selected from the group consisting of a potassium salt, a magnesium salt, a calcium salt, and an ammonium salt,
the taste improvement method comprising adding a taste improver comprising as an active ingredient, a vegetable extract, which comprises at least one material selected from the group consisting of apigenin, daidzin, and a glycoside of apigenin, to the foodstuff.

2. The taste improvement method according to claim 1 ,
wherein the taste improver further comprises as an active ingredient a phospholipid.

3. The taste improvement method according to claim 2 , wherein the phospholipid is phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine, or phosphatidylinositol, or any of lyso forms thereof.

4. The taste improvement method according to claim 3 , wherein the phospholipid is an extract of a plant, an animal, a fungus, or combinations thereof.

5. The taste improvement method according to claim 2 , wherein the phospholipid comprises at least one material selected from the group consisting of phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine, phosphatidylinositol, and any of lyso forms thereof.

6. The method according to claim 2 ,
wherein the taste improver is added to the foodstuff so that, upon adding the taste improver to the foodstuff, a concentration of the vegetable extract as a solid content relative to the foodstuff or a concentration of the phospholipid, in the foodstuff is in a range from 0.001 to 1 percent by weight relative to the foodstuff.

7. The taste improvement method according to claim 1 , wherein the vegetable extract comprises apigenin, glycoside of apigenin, or a combination of apigenin and a glycoside of apigenin.

8. The taste improvement method according to claim 1 , wherein the vegetable extract is an extract of any of paprika, asparagus, burdock, tomato, bitter melon, parsley, green soybean, purple-fleshed sweet potato, carrot, garland chrysanthemum , spinach, barley grass, Angelica keiskei, mulberry leaves, Japanese radish, Corchorus olitorius, kale, yam, broccoli, green pepper, and celery.

9. The taste improvement method according to claim 1 , wherein the vegetable extract is extracted using water, ethanol, or a combination thereof.

10. The taste improvement method according to claim 1 , wherein the taste improver further comprises a basic amino acid.

11. The taste improvement method according to claim 10 , wherein the basic amino acid is arginine.

12. The taste improvement method according to claim 1 , wherein the taste improver further comprises a saccharide.

13. The taste improvement method according to claim 12 , wherein the saccharide is trehalose, a hydrogenated starch syrup, or a combination thereof.

14. The method according to claim 1 ,
wherein the taste improver is added to the foodstuff so that, upon adding the taste improver to the foodstuff, a concentration of the vegetable extract in the foodstuff as a solid content is in a range from 0.001 to 1 percent by weight relative to the foodstuff.

15. The method according to claim 14 ,
wherein the taste improver optionally contains a phospholipid
wherein, upon adding a saccharide, a basic amino acid, or a combination thereof to the foodstuff together with the vegetable extract and optionally with the phospholipid as the taste improver, a content of the saccharide if added is in a range from 2 to 100 parts by weight relative to 1 part by weight of the added vegetable extract or a combination of the vegetable extract and the phospholipid, respectively, and
a content of the abasic amino acid if added is in a range from 0.1 to 10 parts by weight relative to 1 part by weight of the added vegetable extract or the added combination of the vegetable extract and the phospholipid, respectively.

16. salt substitute comprising a taste improver comprising as an active ingredient, a vegetable extract, which comprises at least one material selected from the group consisting of apigenin, daidzin, and a glycoside of apegenin,
wherein the taste improver is contained in the salt substitute in an amount range from 0.001 to 1 part by weight as a solid content of the vegetable extract relative to 1 part of a total amount of at least one salt selected from the group consisting of a potassium salt, a magnesium salt, a calcium salt, and/or an ammonium salt, contained in the salt substitute.

17. The salt substitute according to claim 16 , further comprising a phospholipid, arginine, or a combination thereof,
wherein an amount of the phospholipid if contained is in a range from 0.001 to 1 part by weight and an amount of the arginine if contained is in a range from 0.02 to 2.5 parts by weight, relative to 1 part of a total amount of a potassium salt, a magnesium salt, a calcium salt, and an ammonium salt in the salt substitute.

18. A taste improvement method for a foodstuff comprising at least one salt selected from the group consisting of a potassium salt, a magnesium salt, a calcium salt, and an ammonium salt,
the taste improvement method comprising adding a taste improver comprising as an active ingredient, at least one material selected from the group consisting of apigenin, daidzin, and a glycoside of apigenin, to the foodstuff.

19. The taste improvement method according to claim 18
wherein the foodstuff comprises apigenin, daidzin, or a glycoside of apigenin in an amount from 10 ppm to 150 ppm.
