Decomposition inhibitor of chlorophyll, anti-fading method of chlorophyll-containing foods and chlorophyll-containing foods containing the stabilizing agent of the chlorophyll

摘要

PROBLEM TO BE SOLVED: To prevent the fading of a chlorophyll-containing food by including ferulic acid (an alkali metal salt) as an active ingredient. ;SOLUTION: This preventing agent for decomposition of chlorophyll is obtained by including ferulic acid (3-methoxy-4-hydroxycinnamic acid) or its alkali metal salt as an active ingredient. Although the ferulic acid even in the form of a free acid prevents the decomposition of the chlorophyll, the ferulic acid is somewhat sparingly soluble in water and sourness is sometimes felt. Thereby, the ferulic acid is advantageously used in the form of the alkali metal salt such as a monosodium salt or an organic acid salt or an inorganic acid salt having buffering actions such as sodium acetate is advantageously formulated so as to provide pH 4.5-8 when converted into an aqueous solution at the time of preparing a formulation. An optional form such as a powdery, a granular, a pasty or a liquid form can be adopted as the dosage form.;COPYRIGHT: (C)2000,JPO
