Abstract
The invention relates to the field of feed processing, in particular to a method for producing a food attractant by using a waste fish soluble extract in a processing process of fish meal. The method produces a food attractant capable of improving the feed palatability of aquaculture animals by taking the waste and fish soluble extract from the production of the fish meal as a raw material and by the procedures of steam boiling, mixing, fermentation, drying, and packaging. By the processing and enzymolysis, the polymer proteins in the fish soluble extract are hydrolyzed into small peptides and free amino acids, so the absorption utilization ratio and the food attraction of the fish soluble extract are improved. The method has the advantages of making the waste profitable by using the processing waste from the fish meal as the raw material, reducing the pollution of discharged fish meal to the environment, along with environment friendliness, stable source of the raw material, and simple production process.
Description
[technical field]
The present invention relates to field of feed processing, relate in particular to a kind of method of utilizing the molten slurry of waste fish in the fish meal process to produce phagostimulant.
[background technology]
At present, a large amount of palatabilities that cause feed of using of plant protein material descend in the aquatic feeds, therefore the suitable aquatic animal phagostimulant of very necessary exploitation.
The molten slurry of fish is the squeezing waste water that produces in the fish meal production process.In the early stage fish meal production process, the molten slurry of fish directly discharges in environment without reclaiming usually, has caused serious environmental pollution.In recent years, the existing more research of the method that the molten slurry of relevant fish is recycled, dry (Chinese patent CN200710030735.9) in the fish meal as the molten slurry of fish is added, or be dried to fish soluble slurry protein powder (Chinese patent CN200710120346.5) etc. through de-oiling, unsticking polysaccharide after processing.Because the molten slurry of fish contains soluble protein and free amino acid in the Fish tissue, and stronger fishy smell flavor is arranged, aquatic livestock is had stronger food calling effect, therefore have the potentiality as aquatic attractant.But contain more macro-molecular protein in the molten slurry of fish, such as collagen, peptone etc., limited its digestive utilization ratio.By processing and macromolecule protein in the molten slurry of fish is hydrolyzed into little skin to enzymolysis processing and free amino acid not only can improve its absorption rate, can also improve its food calling effect, therefore its raw materials for production as the aquatic feeds phagostimulant be had stronger feasibility.
[summary of the invention]
The purpose of this invention is to provide a kind of method of utilizing the molten slurry production of fish can improve the phagostimulant of aquatic animal feed palatability.
For above-mentioned purpose, the technical solution used in the present invention is as follows:
A kind of method of utilizing the molten slurry of fish to produce phagostimulant comprises following step:
(1) the molten slurry of fish is injected the rustless steel container of 500L, high-temperature heating boiling 30-60 minute;
(2) the molten slurry of fish is cooled to 37 ℃ after boiling, adds 1000-2000g trypsase and 500-1000g papain in the 500L container, after mixing 37 ℃ of condition bottom fermentations 3-5 hour;
(3) material after protease fermentation again heat boil concentrated, stopped heating when treating that moisture is 50%-60%, add Flavourzyme flavor protease 500-1000g after being cooled to 37 ℃, bud pole bacterium 3000-5000g, lactic acid bacteria 3000-5000g, glycine 300-500g, taurine 200-300g continues fermentation 1.5-2 hour under 37 ℃ of conditions after mixing;
(4) again the product after the fermentation to be dried to moisture through vacuum drying chamber be 30-35%, obtain phagostimulant of the present invention, then inject to pack in the sealed plastic barrel and get final product.
Final products are grey or light brown slurry, strong flesh of fish fragrance are arranged, free from extraneous odour.
The phagostimulant of the improved aquatic animal feed of gained palatability according to the method described above, the addition in aquatic animal feed is the 3%-6% of aquatic animal feed quality.
The pressed liquor that obtains of squeezing step of preparation fish meal is carried out Separation of Solid and Liquid, and it namely is fish oil that the liquid part gets upper strata grease through the high speed centrifugation layering, and lower floor namely is the molten slurry of fish, and the molten slurry of fish with after fish oil separates, is namely got raw material of the present invention.The present invention has following advantage: (1) phagostimulant after by fermentation is rich in natural ocean amino acids material, can significantly improve aquatic livestock to the palatability of feed; (2) ferment by the secondary fermentation technology, both guaranteed that the high molecular weight protein in the molten slurry of fish can fully be hydrolyzed, guaranteed that again the probio of secondary fermentation can survive in the phagostimulant product; (3) add probiotics preparation, suppressed the breeding of the harmful mushroom in the final products, can improve immunity and the premunition of aquatic livestock simultaneously, also have-have made to order usefulness to improving water quality; (4) nontoxic secondary residual, without the resistance to the action of a drug, reduced simultaneously the molten slurry discharging of fish to the pollution of environment, environmental protection; (5) raw materials enjoy stable sources of this phagostimulant, production technology is simple.
[specific embodiment]
Fish meal is squeezed the molten slurry injection of the fish after Separation of Solid and Liquid 500L rustless steel container in the step, high-temperature heating is cooled to 37 ℃ after 30 minutes, add 1000g trypsase and 1000g papain in the container, after mixing 37 ℃ of condition bottom fermentations 3 hours; Material after protease fermentation again heat boil concentrated, stopped heating when treating that moisture is 50% adds Flavourzyme flavor protease 500g, bud pole bacterium 5000g, lactic acid bacteria 3000g, glycine 500g after being cooled to 37 ℃, taurine 300g continues fermentation 1.5 hours after mixing under 37 ℃ of conditions; Product after the fermentation is 30% through vacuum drying to moisture again, obtains phagostimulant of the present invention, then injects to pack in the sealed plastic barrel to get final product.
This product is used in penaeus vannamei boone feed according to 5% addition, cultivate initial body weight and be about 0.289 Penaeus Vannmei, through 2 months growth tests, the Penaeus Vannmei that adds phagostimulant of the present invention in the feed improves 21% with the control group that does not add phagostimulant than grazing rate, and specific growth rate improves 15%.
Average weight reached 25g after the cobio prelarva of interpolation phagostimulant about 6%, 0.29 of the present invention cultivated one month in cobio prelarva feed, was significantly higher than and did not add phagostimulant group of the present invention (22g).
Add phagostimulant 3% of the present invention in crab feed, cultivation is used through the whole year, and final crab listing specification accounts for 87% more than 3 liang, is significantly higher than and does not add phagostimulant group of the present invention (68%).
