INHIBITOR FOR FORMATION OF OFF-ODOR FROM CITRAL OR CITRAL-CONTAINING PREPARATION

摘要

PROBLEM TO BE SOLVED: To provide an inhibitor for the formation of a citral-originated off-odor which is highly safe and does not affect the inherent flavor of a preparation in order to solve the problem wherein the citral of a citral-containing preparation changes in its structure due to reactions such as cyclization, hydration and isomerization in each stage of its production, distribution, storage, etc., and further forms a very strong off-odor such as p-cresol or p-methylacetophenone due to an oxidation reaction and to provide a method for inhibiting the off-odor.;SOLUTION: The inhibitor contains at least one solvent extract selected from the group consisting of Ashitaba (Angelica keiskei (mig.) Koidz.); avocado (Persea Americana); psyllium (Plantago asiatica L.); semi-fermented tea leaves; fermented tea leaves, sicklepod (Cassia obtusifolia L.); and hawthorn (Crataegus cuneata Sieb. et Zucc.).;COPYRIGHT: (C)2004,JPO
