Description

A kind of preparation method who contains the feed addictive of lentinan and small-molecular peptides
Technical field
The present invention relates to feeding additive aquatic animal processing method field, refer more particularly to a kind of preparation method who contains the feed addictive of lentinan and small-molecular peptides.
Background technology
Lentinan is the effective active composition that from mushroom, extracts; Main component is polysaccharide and unrighted acid; The ergosterol and the fungisterol that also contain a large amount of changed into vitamin Ds; Through the lentinan scalable people Xiu Nei of hot water extracting the T cytoactive of immunologic function is arranged, can reduce the ability of methyl cholanthrene induced tumor.Mushroom has had strong inhibitory effects to cancer cell, is 97.5% to the inhibiting rate of small white mouse sarcoma 180, is 80% to the inhibiting rate of ehrlich carcinoma.Mushroom also contains double stranded RNA, can induce the generation interferon, has anti-virus ability.Lentinan can also improve the activity of the superoxide dismutase (SOD) of body in addition, and has the effect of removing free radical.
Peptide is a kind of biochemical substances between amino acid and protein, and it is littler than protein molecular weight, and is bigger than amino acid molecular amount, is a fragment of protein.By tens amino acid peptide bonds are continuous to aggregate into peptide down to reaching more than two, being joined with side chain by a plurality of peptides aggregates into protein again.Link to each other with peptide bond between the plural amino acid, " amino acid chain " of formation or " amino acid string " just are called peptide.Wherein, 10 peptides of forming with upper amino acid are called as polypeptide, and just are called oligopeptides by what 2 to 9 amino acid were formed, just are called small-molecular peptides or little peptide by what 2 to 4 amino acid were formed.It is reported that small-molecular peptides can directly get in the cell with original shape through the infiltration of cell membrane, and do not need to digest once more, also do not need consumes energy, thus the absorption of small-molecular peptides, conversion and utilization have efficiently, fully, characteristics completely.Small-molecular peptides has very strong biologically active, participates in the synthetic of enzyme, excites the activity of enzyme, strengthens the function of enzyme, keeps the stable of enzyme; Through synthetic specific protein, produce special physiological effect.Small-molecular peptides is dual for the effect of cell, and the demand repair deficiency that promptly can supplement the nutrients can improve functional status again.
Existing feeding additive aquatic animal can not improve the immunocompetence of letting animals feed mostly well, becomes the limiting factor that Aquatic Feed Processing is made.The research and development of green feeding additive aquatic animal also be into year over the developing direction of the sector, guarantee that letting animals feed is green, environmental protection is the matter of utmost importance of aquaculture industry.The present invention utilizes mushroom stems leftover bits and pieces and aquatic products processing leftover bits and pieces to be raw material; Form the feeding additive aquatic animal that is rich in lentinan and small-molecular peptides through fermentation; Raw material draws materials itself just to have embodied turns waste into wealth; The aim of safety and environmental protection, the feed addictive that the present invention simultaneously produces can improve the immunity of letting animals feed preferably.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point of the prior art and provide a kind of technology simple, turn waste into wealth, the preparation method of the feed addictive that contains lentinan and small-molecular peptides easy to make.
The present invention realizes through following mode:
A kind of preparation method who contains the feed addictive of lentinan and small-molecular peptides is characterized in that:
Concrete steps are following:
One. the lentinan preparation:

(2), liquid preparation of producing enzyme cultivation and enzyme liquid:
Scrape 1 ring Trichoderma viride spore inoculating in the triangular flask that contains the potato fluid nutrient medium with oese, mixing is placed 28 ℃ the middle 72h of cultivation of biochemical incubator (or shaking table); Get mixed-culture medium and carry out low-speed centrifugal (or qualitative filter paper filtration), get supernatant and be required enzyme liquid;
(3), the preparation of mushroom stems saccharification liquid:
Mushroom stems powder after the ultramicro grinding of learning from else's experience carries out enzymolysis with enzyme liquid in the step (two), and the bulky grain residue of removing in the enzymolysis product promptly gets mushroom stems saccharification liquid;
(4) lentinan formulations prepared from solutions:
Behind double medium filtration, gained filtrating is through hold over night AUTOMATIC ZONING, centrifugal with gained mushroom stems saccharification liquid in the step (three), and the supernatant of gained is lentinan solution;
Two. the small-molecular peptides preparation:
(1), water intaking product processing fent, remove impurity after, add entry, utilize the homogenate of tissue homogenate crusher machine then;
(2), the homogenate of step () gained is added the marine low temperature alkali protease, carry out enzymolysis, obtain enzymolysis liquid behind the enzymolysis;
(3), with the enzymolysis liquid of step (two) through screen filtration, obtain filtered fluid after the filtration;
(4), the filtered fluid of step (three) is carried out centrifugal filtration with the butterfly centrifugal machine, supernatant;
(5), with step (fours') supernatant, carry out second ultrafiltration and concentrate, make small-molecular peptides solution, and it is subsequent use to add stabilizing agent;
Three. contain the preparation of the feed addictive of lentinan and small-molecular peptides:
Step 1 gained lentinan solution is fully mixed with step 2 gained small-molecular peptides solution, and lentinan solution is 1: 5~10 with small-molecular peptides liquor capacity ratio, carries out spray-drying, promptly gets the feed addictive that contains lentinan and small-molecular peptides after the drying.
The preparation method of described potato fluid nutrient medium is with peeling potatoes, is cut into piece and adds water, boils 30min, uses filtered through gauze, and gained filtrating adds glucose, supplies water to 100ml, the triangular flask of packing into.
Protein in the described marine low temperature alkali protease ability hydrolyzed aquatic products processing fent discharges small-molecular peptides, and the grease that hydrolysis simultaneously produces can be used for Feed Manufacturing.
Can be used for Feed Manufacturing after the described upper strata grease drying with the centrifugal filtered fluid of butterfly centrifugal machine.
The present invention utilizes lentinan can improve superoxide dismutase activity and other various biological functions, has immunoregulation effect, also can activate the characteristics of the BA of small-molecular peptides simultaneously.Small-molecular peptides also has the various biological effect, is used for the effect that feed addictive can not only be brought into play lentinan and small-molecular peptides self, and a collaborative effect that strengthens is arranged simultaneously each other, can improve immunocompetence significantly.The nutritive value of lentinan and small-molecular peptides self also can improve feed efficiency.
