(CH!1.C0OH was used to prepare astaxanthin cabroyl ester. 130 mg of this astaxanthin cabroyl ester was mixed into 100 g of control feed in the same manner as in Example 1, and 10 g of each was used.
We investigated the stability of astaxanthin cicabroyl ester, which is the same as that of the previous study, in feed.As shown in the results, astaxanthin cicabroyl ester was extremely stable compared to other samples.
