Problems solved by technology

[0004] There are many methods for the production of food attractants by using fish soluble pulp. The existing technology, such as the Chinese invention patent with the authorized public number CN101904412 B, discloses a method for producing food attractants from fish soluble pulp. This method has the characteristics of simple process and so on. , but the residual fat in the food attractant produced by it is easy to cause acidosis to fish, and it cannot effectively enzymatically hydrolyze the protein of different fish solubles, which is not suitable for digestion and absorption, and its final product is in a liquid state, which is inconvenient to store and transport

Embodiment 1

[0016] A feed attractant produced by using fish-dissolved pulp is obtained through sterilization, degreasing, enzymatic hydrolysis, fermentation, fishy-enhancing and molding processes.

[0017] A method for producing a food attractant by utilizing fish-dissolved pulp, the specific operation steps are:

[0018] 1) Sterilization: Pour 500kg of fish-dissolved slurry into a 1000L sealed stainless steel container and cook for 40 minutes at a pressure of 60MPa and a temperature of 120°C. The basic principle of 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.

[0019] 2) Degreasing: Add 7kg of lipase to the fish soluble slurry obtained in step 1, stir and ventilate at 35°C, let it react for 1.5 hours, complete lipolysis and fatty acid oxidation, and obtain defatted fish soluble slurr...

Embodiment 2

[0025] A method for producing food-attractant by using fish-dissolved pulp, comprising: sterilization, degreasing, enzymatic hydrolysis, fermentation, increasing fishy smell, and molding, specifically including the following steps:

[0026] 1) Sterilization: Pour 500kg of fish-dissolved slurry into a 1000L sealed stainless steel container, and cook for 30 minutes at a pressure of 80MPa and a temperature of 140°C. The basic principle of 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.

[0027] 2) Degreasing: add 6.5kg of lipase to the fish soluble slurry obtained in step 1, stir and ventilate at 35°C, let it react for 1.5h, complete lipolysis and fatty acid oxidation, and obtain defatted fish soluble slurry. Lipase hydrolysis and fatty acid oxidation can effectively prevent fat...

Embodiment 3

[0033] A method for producing food-attractant by using fish-dissolved pulp, comprising: sterilization, degreasing, enzymatic hydrolysis, fermentation, increasing fishy smell, and molding, specifically including the following steps:

[0034] 1) Sterilization: Pour 500kg of fish-dissolved slurry into a 1000L sealed stainless steel container, and cook for 45 minutes at a pressure of 80MPa and a temperature of 140°C. The basic principle of 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.

[0035] 2) Degreasing: Add 6.2kg of lipase to the fish soluble slurry obtained in step 1, stir and ventilate at 35°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 preven...

Abstract

The present invention discloses a phagostimulant produced by using fish soluble slurry. The phagostimulant is obtained by fish soluble slurry microorganism removing, defatting, enzymolyzing, fermenting, fishy smell increasing and shaping. Beneficial effects are as follows: residual fat in the fish soluble slurry is completely enzymolyzed and a ventilation is conducted to enable fatty acids produced by the enzymolyzing to be completely oxidized; proteins are completely hydrolyzed into oligopeptides, amino acids and small molecules beneficial to digestion and absorption of fish; active polypeptides can affect proliferation of fish intestinal microorganisms, activate pepsinogen and improve a feed conversion rate; trimethylamine oxide dehydrate is significantly in fishy smell increasing functions and can maximally play an attraction function of the phagostimulant; and a finished product of the phagostimulant is powdery, easy for storage and transportation, long in shelf life under a normal temperature condition, reasonable in design and convenient in operations, turns a waste of the fish soluble slurry into treasures, reduces harms of a production of fish meal on environment, and improves resource utilization rate and added value.

Description

technical field [0001] The invention relates to the field of aquatic feed processing, in particular to a food-attractant produced 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 fishmeal production process. For every ton of fish meal produced, 2~3 tons of fish soluble slurry will be produced. Because it contains a large number of small molecular 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 poultry an...
