Antioxidant, antioxidant composition and production method therefor

摘要

Problem;To provide an antioxidant, an antioxidant composition, and a method for producing the antioxidant and the antioxidant composition, which feature a high content rate and degree of extraction of substances. These substances are taurine, glycogen, protein, so-called blood platelet anticoagulant with zinc, fat-soluble vitamin with a high activation such as vitamin D, and other useful substances. The antioxidant and the antioxidant composition also feature a so-called antioxidative property, which has recently attracted attention.;Solution;The present invention, for example, includes 3,5-dihydroxy-4-methoxybenzyl alcohol.

主权项

1. A method for producing an antioxidant composition, comprising:
(1) adding an oyster meat to an extraction container containing water to obtain an extract liquid containing an oyster meat extract; (2) concentrating the extract liquid; (3) adding liquid ethanol to the concentrated extract liquid to achieve an ethanol concentration of 70%, then stirring a resulting liquid; (4) after stirring, the liquid of step (3) is allowed to rest to separate a precipitate and a supernatant; (5) removing the ethanol from the supernatant; (6) concentrating the supernatant resulting from step (5) until an amount of the solution is half that of step (5); (7) diluting the concentrated liquid of step (6) so as to quintuple the amount of the concentrated liquid of step (6) to remove impurities; (8) adding ethyl acetate to the liquid of step (7) to achieve a solution; (9) separating the solution of step (8) into a water layer and an ethyl acetate layer with a separator; and (10) recovering a 3,5-dihydroxy-4-methoxybenzyl alcohol fraction from the ethyl acetate layer.
