Abstract
The invention provides a preparation method of fat for marine fish. The method is characterized by comprising the following steps of: squeezing flaxseed or purple perilla seed serving as raw material according to a cold-pressing squeezing method at a temperature lower than 60 DEG C; quickly separating oil from slag for standby by using a high-speed centrifuge at a speed of 20,000-12,000 r/min, wherein the separated oil is flaxseed oil or purple perilla seed oil of which the main component is alpha-linolenic acid; preparing fish oil by using flaxseed oil or purple perilla seed oil accounting for 50-80% of the total weight of marine fish feed and fish oil accounting for 20-50%; adding vitamin E and vitamin C, which respectively account for 0.20-0.35% and 0.25-0.40% of the total weight of marine fish feed, in the prepared fish oil; and evenly mixing to finally obtain the low-price high-quality fish feed, particularly referring to the fat for marine fish. The preparation method has the advantages that the defects of the conventional feed design formula are overcome, which is proved by tests; the cultivation cost of marine fish is reduced; and the development of aquaculture industry is promoted.
Description
Technical field:
That the present invention relates to is the preparation method of a kind of seawater fish with fat.Belong to feed and field of feed additive technology.
Background technology:
Fat is the energy and the important source of required essential fatty acid of growing, and can promote the absorption of liposoluble vitamin.Fat is prevented under the digestive ferment effect; Be decomposed into the mixture of single glyceride of 2-and FFA; Be used for synthetic various cell components after the fish absorption or be decomposed into energy; Fat is the important energy sources of various fish, particularly carbohydrate is utilized seawater fish limited in one's ability and cold water fish, and the energy of fat seems extremely important.The fat content of seawater fish reaches about 10%, and the fat content of cold water fishes can be up to about 20%, and the warm water fishes requirement has 7-8% just can satisfy the demand.Not enough or the shortage of fat content can cause the fish metabolic disorder in the feed, and the feed protein utilization rate descends, simultaneously also can concurrent liposoluble vitamin and essential fatty acid deficiency.So fat is the necessary one type of important nutriment of fish growth.Fat is divided into saturated fat and unsaturated fat again.Facts have proved no matter be cold water fish or warm water fish, add the poor (in feed, adding saturated fat abiology meaning) of saturated fat.The addition of fish oil reaches 3-7% in marine fish feed, and eicosapentaenoic acid in the fish oil (EPA) and DHA (DHA) content are high, and is to belong to the high unsaturated polyenoic fatty acid of ω-3 series.The serial polyenoic fatty acid of ω-3 can not synthesize in animal body, must be from external picked-up.The fish oil price is higher, and addition is big again, causes marine fish feed to hold at high price, and has influence on the development of marine fish culture.Though the breeding seawater fish is often used the ice fresh fish at present, price is low, and resource is day by day burst and exhausted, and seawater pollution breaks out fish disease, causes vicious circle, and its potential danger is bigger.Also useful in addition soya-bean oil and fish oil mix and substitute fish oil to reduce cost; But soya-bean oil belongs to ω-6 series fatty acid; (ω in the plant protein material of feed-6 series fatty acid does not lack, and what lack is the serial polyenoic fatty acid of ω-3) more can't change into eicosapentaenoic acid (EPA) and DHA (DHA).
Alpha-linolenic acid is called for short LNA; Belong to the serial polyenoic fatty acid of ω-3 (writing a Chinese character in simplified form PUFA); Be all-cis formula 9,12,15 octatecatrienoic acids; It is present in the bottle green plant with the form of glyceride, and content is very high in linseed oil and Purple Perilla Seed Oil, and leukotrienes is closely gone into the dehydrogenase and the carburetting enzyme that all have a kind of liver to produce behind the animal body and come metabolism and be converted into body essential vital activity factor D HA and EPA.Utilize its this conversion characteristic, in marine fish feed, add the alternative part fish oil of a certain amount of linseed oil or perilla herb oil, just can obtain cheap and good-quality feed.Particularly marine fish culture is of far-reaching significance to China's aquaculture for this.
Summary of the invention:
The present invention proposes the preparation method of a kind of seawater fish with fat, is intended to overcome the existing existing above-mentioned defective of feed component design, to reduce the marine fish culture cost, promotes the development of culture fishery.
Technical solution of the present invention: a kind of seawater fish comprises following technology with the preparation method of fat:
One, extruding is pushed raw material linseed or purple perilla seed by the milling process of colding pressing, temperature is less than 60 degree;
Two, separate, use supercentrifuge, centrifuge speed 20000-12000r/min separates oil and slag back subsequent use fast; Isolated linseed oil or the perilla herb oil of being, linseed oil or purple perilla main body of oil are alpha-linolenic acids;
Three, preparation,
1) in marine fish feed, is configured to fish oil with the linseed oil that accounts for gross weight 50-80% or the fish oil of perilla herb oil and 20-50%;
2) in the above-mentioned fish oil that is configured to, add vitamin E that accounts for gross weight 0.20-0.35% and the vitamin C that accounts for gross weight 0.25-0.40%;
3) mixing and stirring promptly obtains cheap and good-quality fish meal seawater fish with fat.
Beneficial effect of the present invention: add in the feed omega-3 unsaturated fatty acid can:
1, improves immunologic function, strengthen resistance against diseases, improve efficiency of feed utilization, improve carcass quality.
2, improve Endogenous Hormone Contents in Vitro, promote animal growth.
3, regulate each item metabolic index, guarantee the animal health growth.
4, reduce feedstuff-meat ratio, improve meat matter, effect is remarkable.
Alpha-linolenic acid, DHA (DHA) and eicosapentaenoic acid (EPA) all are the serial polyenoic fatty acids of ω-3.Alpha-linolenic acid is gone into behind the animal body with self enzymes metabolism and is converted into high unsaturated fatty acid DHA (DHA) and eicosapentaenoic acid (EPA).Alpha-linolenic acid mainly can extract from the linseed of cheapness or purple perilla seed, and its price has only 60% of fish oil, and DHA (DHA) and eicosapentaenoic acid (EPA) can only extract from deep sea fish oil, costs an arm and a leg, and resource is day by day burst and exhausted.And western China is abounded with flax and purple perilla, and aboundresources is the good project that development of the West Regions is got rich.Therefore this invention has favorable economic benefit and social benefit.
