The present invention relates to a deterioration preventive for a flavor component, which is an oil-in-water and/or -polyhydric alcohol type emulsion, comprising an extracted tocopherol, wherein d-&#x3b4;-tocopherol is contained in an amount of 45% by weight or more of a total tocopherol, ferulic acid and/or a derivative thereof, and a polyglycerol fatty acid ester; a deterioration preventive for a flavor component, which is an oil-in-water and/or -polyhydric alcohol type emulsion, comprising (A) the above-mentioned extracted tocopherol, (B) ferulic acid and/or a derivative thereof, and (C) an emulsifying agent having an HLB of 9 or more; a flavor for foodstuff, comprising the above-mentioned deterioration preventive; an emulsion flavor for foodstuff, comprising the above-mentioned extracted tocopherol, a catechin; and a polyglycerol fatty acid ester; and foodstuff comprising the above-mentioned deterioration preventive for a flavor component, the above-mentioned flavor for foodstuff, or the above-mentioned emulsion flavor for foodstuff.

Method of preventing flavor component from degradation

A polyglycerol fatty acid ester formed by esterifying a polyglycerol and a fatty acid, wherein the polyglycerol has a hydroxyl value of 1200 or less and primary hydroxyl groups in an amount of 50% or more of the total hydroxyl groups, and an emulsified or solubilized composition, foodstuff, and cosmetics, each containing the polyglycerol fatty acid ester.

Polyglycerol fatty acid ester and composition containing same

A polyether-polyol compound represented by the compositional formula C H O , wherein n is an integer of 4 or more, wherein the polyether-polyol compound has a total number of 1,2-diol unit and 1,3-diol unit of &lsqb;(n/2)&plus;1&rsqb; in a case where n is an even number of 4 or more, or a total number of 1,2-diol unit and 1,3-diol unit of &lsqb;((n&minus;1)/2)&plus;1&rsqb; and one hydroxyl group which is not involved in the units in a case where n is an odd number of 5 or more; a polyglycerol alkyl ether, a part of hydroxyl groups in a polyglycerol being substituted by an alkyl group, wherein the polyglycerol is the polyether polyol compound mentioned above; and an ester prepared by the process comprising reacting the polyether-polyol compound mentioned above or the polyglycerol alkyl ether mentioned above with a fatty acid.
