Abstract
Official abstract text for this publication.
An astringency reducing agent including an arabinogalactan which has a molecular weight of from 10,000 to 1,000,000 and a ratio of 1,3-bound galactose to total galactose of 12 mol % or more, as an active ingredient. A method for reducing astringency, including blending the astringency reducing agent into an oral product including an astringent substance.
First claim
Opening claim text (preview).
The invention claimed is: 1 . An astringency reducing agent, comprising an arabinogalactan which has a molecular weight of from 10,000 to 1,000,000 and a ratio of 1,3-bound galactose to total galactose of 18 mol % to 60 mol %, as an active ingredient; and at least one carrier for formulation, selected from the group consisting of an excipient, a binder, an extender, and a diluent, wherein the astringency reducing agent is substantially free of proteins, lipids, and carbohydrates other than the arabinogalactan. 2 . The astringency reducing agent according to claim 1 , wherein the ratio of 1,3-bound galactose to total galactose is from 18 to 50 mol %. 3 . The astringency reducing agent according to claim 1 , wherein the molecular weight is from 10,000 to 500,000. 4 . The astringency reducing agent according to claim 1 , wherein astringency from polyphenol is reduced. 5 . The astringency reducing agent according to claim 4 , wherein the polyphenol comprises a non-polymeric catechin. 6 . A method for reducing astringency, comprising blending an astringency reducing agent, comprising an arabinogalactan having a molecular weight of from 10,000 to 1,000,000 and a ratio of 1,3-bound galactose to total galactose of 18 mol % to 50 mol % as an active ingredient into an oral product comprising an astringent substance. 7 . The method for reducing astringency according to claim 6 , wherein the oral product comprising an astringent substance is at least one beverage selected from green tea, black tea and oolong tea or a food product containing any of these beverages. 8 . The astringency reducing agent according to claim 1 , wherein the arabinogalactan is a pear-derived arabinogalactan isolated from pear. 9 . The method according to claim 6 , wherein the astringency reducing agent is substantially free of proteins, lipids, and carbohydrates other than the arabinogalactan.
