Meat quality flavor modifying agent for grass carp or carp and preparation method thereof

Abstract

The invention relates to a feed additive of aquaculture industry, in particular to a meat quality flavor modifying agent for grass carp or carp and a preparation method thereof. Each kilogram of modifying agent comprises the following components: 30 to 50g of seaweed extract, 10 to 20g of combination of inosinic acid and guanylic acid, 20 to 30g of carnitine, 15 to 30g of glycin, 10 to 20g of alanine and the balance of zeolite powder. The preparation method comprises the following steps: firstly, crushing solid materials in the seaweed extract, the combination of inosinic acid and guanylic acid, the carnitine, the glycin, the alanine and the zeolite powder materials and sieving the crushed solid materials through a sieve with 80 to 100 meshes for later use; and secondly, mixing and stirring the crushed solid materials in the proportion to ensure that the coefficient of variation CV of the uniformity is less than 5 percent to obtain the product. The modifying agent can effectively improve protein content, content of total amino acids, content of essential amino acids and content of delicious amino acid in muscles of the grass carp and the carp.

Description

technical field [0001] The invention relates to a feed additive for aquaculture, in particular to a meat flavor improver for grass carp or carp and a preparation method thereof. Background technique [0002] Grass carp and carp are dominant species in traditional aquaculture in my country, and their output accounts for more than 25% of freshwater aquaculture in my country. With the rapid development of the modern aquaculture industry, irrational drug use is common in the artificial breeding of grass carp and carp, the protein content of the bait is low and the amino acid is unbalanced, and the breeding cycle is short, coupled with the deterioration of water quality, which often leads to the meaty flavor of the artificially cultured grass carp or carp. poor. It is manifested in: compared with natural wild fish or extensive farming products, artificially farmed products have poor color, less edible parts, low lean meat rate, low ratio of essential amino acids, essential amino...

With the rapid development of the modern aquaculture industry, irrational drug use is common in the artificial breeding of grass carp and carp, the protein content of the bait is low and the amino acid is unbalanced, and the breeding cycle is short, coupled with the deterioration of water quality, which often leads to the meaty flavor of the artificially cultured grass carp or carp. poor

It is manifested in: compared with natural wild fish or extensive farming products, artificially farmed products have poor color, less edible parts, low lean meat rate, low ratio of essential amino acids, essential amino acid index, and three nutritional indicators of protein, while High body fat content, loose meat, poor taste, strong earthy smell, reduced umami taste, and the product flavor is not as delicious as wild fish in nature
