Large yellow croaker feed additive for reducing body fat and promoting flavor

Abstract

The invention discloses a large yellow croaker feed additive for reducing body fat and promoting flavor, which is prepared by uniformly mixing the following raw materials in parts by weight: 2-3 parts of L-carnitine, 20-30 parts of betaine and 60-70 parts of conjugated linoleic acid. After a daily complete formula feed is added with the additive (accounting for 2-3wt% of the daily complete formula feed), the fat content of muscles of large yellow croakers can be significantly reduced, and the contents of flavor compounds (such as flavor amino acids, inosinic acids and trimethylamine oxides) in the muscles of large yellow croakers can be increased; and when the complete formula feed added with the additive is used for feeding large yellow croakers, the fed large yellow croakers are low in fat content, plump in muscle, good in texture, and high in flavor amino acid, inosinic acid and trimethylamine oxide contents of muscles. Thus, the large yellow croakers are enough in freshness, exquisite in meat quality, and good in taste, and can be comparable to wild large yellow croakers.

Description

technical field [0001] The invention relates to a feed additive for large yellow croaker, in particular to a feed additive for large yellow croaker that reduces body fat and improves flavor. [0002] additive. Background technique [0003] Due to factors such as eutrophication and ecological environment, the fat deposits in the muscle of large yellow croaker are relatively high at present, and the content of flavor substances such as umami amino acids, inosinic acid and trimethylamine oxide in the muscle is relatively low, so the taste cannot be obtained. Compared with wild large yellow croaker, the price is also very different. In order to improve the quality of farmed large yellow croaker, researchers have explored from various aspects. For example, the invention patent with the authorized announcement number CN101326966 discloses a feed for improving the quality of large yellow croaker prepared by conjugated linoleic acid, vitamin E and daidzein. Additives, conjugated l...
