Problems solved by technology

Among them, earthworms can emit a special fragrance, have a good food-attracting effect, promote the feeding and digestion and absorption of aquatic animals, reduce the feed coefficient, reduce feed costs, and have various nutrients. It is used as aquatic compound feed to feed aquatic animals. High-quality feed resources are also good food promoters, but at present, earthworms are mainly fed directly to aquatic animals in aquaculture, resulting in adverse effects of low utilization rate, large waste, and high cost
[0005] Prior art, such as the Chinese invention patent with the authorized announcement number CN103005228B, discloses a preparation method and application of an additive for preventing diarrhea and promoting growth of suckling piglets, wherein earthworms are enzymatically hydrolyzed to extract relatively sufficient and highly efficient Free amino acids and low-molecular-weight peptides are used to promote the growth of feeding animals, but the time and cost of earthworm enzymatic hydrolysis is relatively large, and the enzymatic hydrolysis extract has not been processed, which is not conducive to long-term storage

Embodiment 1

[0030] A food attractant for freshwater fish, the food attractant contains earthworm small molecule polypeptide extract, and the above-mentioned promoter for preparing the earthworm small molecule polypeptide extract contains menthol and laurocapram. Adding earthworm small molecule polypeptide extract to the food attractant has a good food attractant effect, can emit special fragrance, can promote feeding and digestion and absorption of aquatic animals, has high utilization rate, reduces feed coefficient, and reduces feed cost. Resources are high-quality attractants.

[0031] The addition amount of solubilizer is 0.67% of the weight of earthworm stoste, and the weight ratio of menthol and laurocapram in the solubilizer is 2.5:1.2, and menthol and laurocapram cause the lipid on the cell membrane and The structure of the protein is denatured, and it can selectively stimulate the cold receptors of the cell mucosa, causing the cell membrane to shrink, resulting in the expansion of...

Embodiment 2

[0044] A food attractant for freshwater fish contains the following raw materials in parts by weight: 24 parts of earthworm small molecule polypeptide extract, 11 parts of yeast flavor substance, 8 parts of nucleotides, 4 parts of sulfur-containing compounds, 8 parts of compound amino acids, 4 parts Color, 0.8 parts antioxidant and 18 parts maltodextrin.

[0045] A method for preparing a food attractant for freshwater fish, comprising preparing an earthworm small molecule polypeptide extract, preparing a yeast flavor substance and preparing a food attractant, specifically comprising the following steps:

[0046] 1) Wash 26 parts of earthworms by weight, put them in clear water and spit out sand, then send the earthworms into a high-speed masher for crushing to obtain the earthworm stock solution, and then add 0.74% of the earthworm stock solution to the earthworm stock solution. Mix the solvent evenly, then add pure water at a weight ratio of 1:1.8, then autolyze and enzymatic...

Embodiment 3

[0052] A method for preparing a food attractant for freshwater fish, in which the Maillard reaction for preparing yeast flavor substances is optimized, and the specific optimization measures are as follows: add xylose, L-cysteine ​​hydrochloride, Thiamine, control agent and vitamin C were reacted for 1.25h at a temperature of 120°C and a pH of 8 to obtain yeast flavor substances, of which self-solution, xylose, L-cysteine ​​hydrochloride, sulfur The weight ratio of amine and vitamin C is 9.5:6:1:3:1, the water content of the initial reaction system is controlled at 15%, the addition of the above-mentioned control agent is 0.33% of the solution weight, and the control agent contains ethyl acetoacetate Ester and calcium pantothenate, the weight ratio is 3:7, ethyl acetoacetate and calcium pantothenate are added to the reaction system to reduce the steric hindrance effect of sugar groups, accelerate the breaking of glycosidic bonds, release carbonyl, and also release carbonyl α ca...

Abstract

The invention provides a feed attractant for freshwater fish and belongs to the technical field of feed processing. The feed attractant contains an earthworm micro-molecular polypeptide extract, and apromoter for preparation of the earthworm micro-molecular polypeptide extract contains menthol and laurocapram. Meanwhile, the invention provides a preparation method of the feed attractant for the freshwater fish. The method comprises the steps of preparation of the earthworm micro-molecular polypeptide extract, preparation of a yeast flavor substance and preparation of the feed attractant, a yeast autolysis solution is used as an amino acid source and a Maillard reaction is conducted to prepare the yeast flavor substance. The provided feed attractant for the freshwater fish has bright color, full and smooth flavor and excellent palatability, is nutrient and healthy, has few toxic and side effects and can improve ingestion enthusiasm of animals and increase the utilization efficiency anddigestive absorption speed of feed to achieve the efficient feed attraction purpose. The preparation method of the feed attractant is simple to operate, simple to control, short in reaction time, high in hydrolysis completeness, high in reaction efficiency, low in production cost, high in active component yield and significant in economic benefits.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and in particular relates to a food attractant for freshwater fish. Background technique [0002] China is a big aquaculture country in the world, and the aquaculture industry provides more than 30% of high-quality protein sources for our people, and the total output of freshwater fish farming accounts for 70% of my country's total fish output. Therefore, freshwater fish is an important part of my country's food security and one of the main sources of animal protein. In recent years, the price of aquatic products in freshwater aquaculture has continued to slump, and the price of raw materials used for feed has remained high, resulting in high aquaculture costs and low aquaculture benefits. Therefore, reducing feed costs is a key link to improve aquaculture efficiency. At the same time, due to the shortage of fishmeal resources and the high price of soybean meal, the addition of fishmeal ...
