摘要:
[Problem] The problem for the present invention is to provide an antioxidation formulation that is highly safe due to derivation from natural substances and that has an effect when used in fish meal that is at least equivalent to that of the presently utilized ethoxyquin. [Means to Solve the Problem] A fish meal contains a vegetable oil distillation-deodorizing distillate as an added antioxidant substance, or the fish meal contains an added vegetable oil distillation-deodorizing distillate and ascorbic acid, or a salt thereof, or an ester thereof A method of production of fish meal controls oxidation by addition of a vegetable oil distillation-deodorizing distillate or by addition the vegetable oil distillation-deodorizing distillate and ascorbic acid, or a salt thereof, or an ester thereof An antioxidation composition for fish meal contains a vegetable oil distillation-deodorizing distillate or the antioxidation composition contains the added vegetable oil distillation-deodorizing distillate and ascorbic acid, or a salt thereof, or an ester thereof A feed is produced by use as raw material of a fish meal to which has been added a vegetable oil distillation-deodorizing distillate or the vegetable oil distillation-deodorizing distillate and ascorbic acid, or a salt thereof, or an ester thereof.
摘要:
[Problem] Provision of a composition for external use on skin that is safe to use and has an anti-inflammatory and anti-allergic actions. [Solution] A composition for external use on skin in the treatment of inflammatory disease which comprises dihomo-γ-linolenic acid (DGLA) as an active ingredient. The DGLA is preferably contained as a glyceride, a phospholipid, or an alkyl ester. The composition for external use contains DGLA in an amount of 0.1-50 wt%.
摘要:
Alcoholysis of oils and fats containing EPA and DHA is performed by a lipase having substrate specificity for fatty acids having 18 carbons or less and in the presence of a reaction additive such as magnesium oxide; then the glyceride fraction is separated; alcoholysis of the glyceride fraction is performed by a lipase having substrate specificity for fatty acids having 20 carbons or less and in the presence of a reaction additive such as magnesium oxide; and EPA-enriched oil and DHA-enriched oil are simultaneously obtained.
