Embodiment 1

[0020] A method for producing an attractant by utilizing fish-dissolved pulp, specifically comprising the following steps:

[0021] 1) Add 0.2 parts of lipase to 500 parts of sterilized fish lysate, stir and ventilate at 35°C, let it react for 1.5 hours, complete lipolysis and fatty acid oxidation, and obtain defatted fish lysate, Lipase hydrolysis and fatty acid oxidation can effectively prevent the metabolites of fatty acids from causing acidosis in fish; 2) Test the pH value of the fish soluble pulp. In an alkaline environment, add 1.2 parts of trypsin, 1.2 parts of elastase and 1.2 parts of Bromelain; in an acidic environment, add 2.5 parts of pepsin, 0.6 parts of papain and 0.6 parts of bromelain to the container, and react for 2 hours under a vacuum of 0.02 MPa to reduce the proportion of amino acid oxidation after hydrolysis , the reaction temperature should be controlled between 35°C to maximize the activity of the enzyme. The products of protein enzymolysis are oligop...

Embodiment 2

[0023] A method for producing an attractant by utilizing fish-dissolved pulp, specifically comprising the following steps:

[0024] 1) Sterilization: Pour 500 parts of fish soluble slurry into a sealed stainless steel container, and cook for 30 minutes at a pressure of 80 MPa and a temperature of 140°C. The basic principle of the sterilization is the lethal effect of high temperature and high pressure on microorganisms, mainly through It is achieved by destroying the cell membrane, inhibiting the activity of enzymes and affecting the replication of genetic material such as DNA;

[0025] 2) Degreasing: add 0.25% lipase to the fish soluble slurry obtained in step 1, stir and ventilate at 36°C, let it react for 1.5 hours, complete lipolysis and fatty acid oxidation, and obtain defatted fish soluble slurry, fat Enzymatic hydrolysis and fatty acid oxidation can effectively prevent the metabolites of fatty acids from causing acidosis in fish;

[0026] 3) Enzymatic hydrolysis: test ...

Embodiment 3

[0031] A method for producing an attractant by utilizing fish-dissolved pulp, specifically comprising the following steps:

[0032] Sterilization: Pour 500 parts of fish soluble slurry into a sealed stainless steel container and cook for 20 minutes at a pressure of 50 MPa and a temperature of 120°C. The basic principle of the sterilization is the lethal effect of high temperature and high pressure on microorganisms, mainly through the destruction of cell membranes Enzyme activity and affect the replication of genetic material such as DNA;

[0033]Degreasing: add 0.2 parts of lipase to the fish soluble slurry obtained after the sterilization step, stir and ventilate at 37°C, let it react for 1.5 hours, complete lipolysis and fatty acid oxidation, and obtain defatted fish soluble slurry, Lipase hydrolysis and fatty acid oxidation can effectively prevent fatty acid metabolites from causing acidosis in fish;

[0034] Enzymolysis: Test the pH value of the fish soluble slurry obtai...

Abstract

The invention discloses a method for producing food calling agent from a fish soluble pulp. The method comprises the following steps of degerming, degreasing, enzymolysis, fermentation, increasing of fish smell and molding. The fish soluble pulp is hydrolyzed by using different proteases under different acidic and basic conditions of the fish soluble pulp. The method has the beneficial effects that residual fat in the fish soluble pulp is completely subject to enzymolysis and is ventilated to thoroughly oxidize fatty acid generated through enzymolysis; protein is thoroughly hydrolyzed into oligopeptides, amino acid and micromolecule which are easily digested and absorbed by fishes; active polypeptides can influence multiplication of fish enteric microorganisms, activate pepsinogen and improve a feed conversion rate; the fish smell increasing effect of dihydrate trimethylamine oxide is obvious, so that the food calling effect of the food calling agent can be exerted to the highest degree; a finished product of the food calling agent is powder, so that the food calling agent is easy to store and transport; the food calling agent has the advantages of long service life under the condition of normal temperature, reasonably design and convenient operation; the fish soluble pulp is changed into things of value from a waste material, the harm of fish meal production to environment is reduced, and the resource utilization rate and the additional value are improved.

Description

technical field [0001] The invention relates to the field of aquatic feed processing, in particular to a method for producing food-attractant by utilizing fish-dissolved slurry. technical background [0002] Aquatic feed is generally made of fish meal, soybean meal, rapeseed meal, peanut meal, heavy calcium powder, bone meal and other raw materials mixed in different proportions. However, raising fish with this kind of aquatic feed often has the problems of poor food-attractiveness, unwillingness to feed, slow feeding speed and low food intake. [0003] Fish soluble slurry is a waste produced in the process of fishmeal production. Every ton of fishmeal produced will produce 2-3 tons of fish soluble slurry, because it contains a large number of small molecule peptides, amino acids, taurine, and minerals, etc. Beneficial ingredients, retaining the unknown growth factors unique to fishmeal, have good food-attracting and growth-promoting effects on aquatic, livestock and poultr...
