Abstract:
1. A method for stabilizing reduced coenzyme Q10 which comprises causing ascorbic acid or a related compound thereof to coexist with a polyglycerol oleic acid ester with a polymerization degree of glycerol being not lower than 3 and/or a condensed ricinoleic acid polyglyceride with a degree of polymerization of glycerol of 4 to 6 in a mixture of the reduced coenzyme Q10 and an oil and fat, wherein the ascorbic acid or a related compound thereof is L-ascorbic acid and/or L-ascorbyl palmitate, the number of oleic acid residues in the polyglycerol oleic acid ester is 1 to 5, the weight ratio of the oil and fat to the sum of the oil and fat and the polyglycerol oleic acid ester and/or condensed ricinoleic acid polyglyceride is 20 to 95%, the weight ratio of the reduced coenzyme Q10 to the sum of the oil and fat and the polyglycerol oleic acid ester and/or condensed ricinoleic acid polyglyceride is 1 to 50%, and a residual reduced coenzyme Q10 ratio after 1 month of storage in the air at 40° C. is not lower than 80% by weight.
