Problems solved by technology

During the breeding process, due to the vigorous life activities and active enzyme systems in catfish, many odorous metabolites are produced. In addition, the feed is generally artificial feed such as fish meal or spoiled miscellaneous fish and shrimp. The smell of fish with fishy smell is stronger and the flavor is greatly reduced. This kind of fishy smell is not accepted by consumers, and it seriously hinders its product development and sustainable development of the industry. At the same time, it needs to improve from the existing feed. How to To avoid a large amount of excrement produced by catfish in the breeding process, it needs to be solved urgently

Embodiment 1

[0014] A kind of feed that improves the flavor of catfish proposed by the present invention, its raw material comprises by weight: 4 parts of guar gum carboxymethyl cellulose sodium compound, 50 parts of high-gluten flour, 16 parts of maltose, 8 parts of antibacterial system, 1 part of hawthorn, 4 parts of grass fruit, 30 parts of germinated brown rice powder, 22 parts of earthworm powder, 10 parts of seaweed powder, 8 parts of pine needle powder, and 3 parts of intestinal accelerator.

Embodiment 2

[0016] A kind of feed that improves catfish flavor that the present invention proposes, its raw material comprises by weight: 8 parts of guar gum carboxymethyl cellulose sodium compound, 40 parts of high-gluten flour, 20 parts of maltose, 4 parts of antibacterial system, 3 parts of hawthorn, 2 parts of grass fruit, 50 parts of germinated brown rice powder, 16 parts of earthworm powder, 16 parts of seaweed powder, 4 parts of pine needle powder, 3.6 parts of intestinal accelerator.

[0017] The guar gum carboxymethyl cellulose sodium complex is prepared by the following process: stir guar gum and water, add sodium acetate buffer solution, adjust the pH value of the system to 7.2-7.6, add mannase and galactose oxidase, adjust temperature, heat preservation, add sodium carboxymethylcellulose, glutaraldehyde and continue to stir to obtain guar gum sodium carboxymethylcellulose complex.

Embodiment 3

[0019] A kind of feed that improves catfish flavor that the present invention proposes, its raw material comprises by weight: 5 parts of guar gum carboxymethyl cellulose sodium compound, 48 parts of high-gluten flour, 17 parts of maltose, 7 parts of antibacterial system, 1.5 parts of hawthorn, 3.5 parts of grass fruit, 35 parts of germinated brown rice powder, 20 parts of earthworm powder, 12 parts of seaweed powder, 7 parts of pine needle powder, and 3.2 parts of intestinal accelerator.

[0020] The guar gum carboxymethyl cellulose sodium complex is prepared by the following process: stir the guar gum and water for 5 hours at a temperature of 60°C, add a buffer solution of 2.3% sodium acetate, adjust the pH of the system to 7.2-7.6, Add mannase and galactose oxidase, adjust the temperature to 65°C, keep warm for 3 hours, add sodium carboxymethylcellulose and glutaraldehyde and continue stirring for 4.5 hours at a stirring speed of 1100r / min to obtain guar gum carboxymethyl fib...

Abstract

The invention discloses a feed for improving leiocassis longirostris flavor, which is prepared from, by weight, 4-8 parts of guar gum sodium carboxymethylcellulose composite, 40-50 parts of high gluten flour, 16-20 parts of maltose, 4-8 parts of bacteriostat system, 1-3 parts of hawthorn, 2-4 parts of Amomum tsao-ko, 30-50 parts of germinated brown rice powder, 16-22 parts of earthworm powder, 10-16 parts of seaweed meal, 4-8 parts of pine needle meal, and 3-3.6 parts of intestinal tract promoter. The feed has advantages of improving immunity and survival rate of leiocassis longirostris, obviously improving the survival rate, increasing economic benefit of artificial cultivation, effectively inhibiting lipoxidase activity, reducing generation of aldehydes material, and greatly decreasing stink odor of leiocassis longirostris; meanwhile, the leiocassis longirostris excrement is few and water body is not polluted.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a feed for improving the flavor of catfish. Background technique [0002] Catfish has rich nutritional value and good health functions, and has become one of the fish species with the highest aquaculture output in the world so far, and is also a member of the high-end hot-selling aquatic products in the world. During the breeding process, due to the vigorous life activities and active enzyme systems in catfish, many odorous metabolites are produced. In addition, the feed is generally artificial feed such as fish meal or spoiled miscellaneous fish and shrimp. The smell of fish with fishy smell is stronger and the flavor is greatly reduced. This kind of fishy smell is not accepted by consumers, and it seriously hinders its product development and sustainable development of the industry. At the same time, it needs to improve from the existing feed. How to Avoid catfish to produce a la...
