Abstract

The invention relates to a making method of a high-protein fermented feed, belongs to the technical field of feed processing, and particularly relates to a making method of the high-protein fermented feed. The making method comprises the following steps of weighing a certain mass of linseed meal, adding sprouted cargo rice powder and ammonium sulfate, adding water and performing uniform mixing so as to obtain a solid culture medium; and enabling the solid culture medium to be subjected to enzymolysis, sterilization, fermentation, low temperature drying, crushing, granulation and packaging, so as to obtain finished products. The high-protein fermented feed disclosed by the invention has the advantages of being rich in nutrition, high in protein content, and good in palatability. In addition, the step of enzymolysis is performed before fermentation, so that nutrition resistant factors having toxicity in the linseed meal are decomposed and released, the eating safety is improved, nutrient substances having health-care efficacies, such as gamma-aminobutyric acid and flavonoid glycosides are also generated, and the health-care efficacies of the fermented feed are improved.

Description

A kind of manufacture method of high protein fermentation feedstuff

Technical field

The invention belongs to feed processing technology field, and in particular to a kind of manufacture method of high protein fermentation feedstuff.

Background technology

Fermented feed be it is artificial it is controllable under the conditions of, with agricultural byproducts as primary raw material, by the metabolism of microorganism Act on high obtained nutritious, protein content, good palatability biological feedstuff or feedstuff.Many microorganisms all have will Inorganic nitrogen changes into the ability of tropina, if adding inorganic nitrogen-sourced, the Jing Guofa such as ammonium sulfate in fermented feed culture medium After ferment these it is inorganic nitrogen-sourced can just change into tropina, therefore, generally can add part nothing in fermented feed culture medium Machine nitrogen, so both provides nitrogen source for strain fermentation, can also increase the protein content of feedstuff after fermentation.

In feedstuff industry, it is a global problem that protein resource is in short supply, and due to populous, resource has for China Limit, shortage is particularly acute, almost every year will the protein feedss raw material such as the substantial amounts of fish flour of import, bean cake.With the increasing of population The continuous improvement of long and living standards of the people, the requirement of protein resource are increasing.New protein sources how are found, is opened up New protein feed resources, are the effective ways for alleviating China's feed protein resource shortage.

In China, although the high-quality protein such as bean cake, fish flour, meat meal tankage lacks, it is necessary to rely on substantial amounts of import, but Semen Gossypii Cake（The dregs of rice）, rapeseed cake（The dregs of rice）, linseed cake（The dregs of rice）Etc. miscellaneous cake（The dregs of rice）Relatively many, this kind of material protein content is high, and does not exist The problem of grain is striven with people and animals, but due to these miscellaneous cakes（The dregs of rice）The antinutritional factor for containing, cause feedstuff absorption rate to be beaten greatly Discount, and serious domestic animal of also causing is poisoned, therefore these miscellaneous cakes（The dregs of rice）Adding proportion in animal feeding-stuff is very low, makes Also it is very restricted with scope.By these miscellaneous cakes（The dregs of rice）The detoxification treatment of the science of carrying out and reasonably use, be Alleviate the effective way that China's protein resource lacks problem.

The content of the invention

It is an object of the invention to provide a kind of manufacture method of the high protein fermentation feedstuff with flaxseed meal as primary raw material.

The object of the present invention is achieved like this：

Sprout brown rice is crushed into obtain germination brown rice powder, the flaxseed meal of certain mass is weighed, flaxseed meal quality 10-15% is added Germination brown rice powder, add the ammonium sulfate of flaxseed meal quality 6-8%, be mixed with water, make material moisture control in 50- 55% solid medium, solid medium is first digested under the conditions of 42-46 DEG C 4-5 hours, then is warming up to 55-60 DEG C of enzymolysis 2-3 hours, then heat to 68-72 DEG C of enzymolysis 40-50 minute, finally sterilize 25-30 minutes under the conditions of 121 DEG C, be cooled to 24-30 DEG C, Candida utilis seed liquor and active dry yeast are inoculated into into above-mentioned solid by 10% and 0.1% inoculum concentration respectively In culture medium, tile after mix homogeneously on tray, send out in relative humidity 85-90%, the growth cabinet of temperature 24-30 DEG C Ferment 70-80 hours, then Jing cold drying, crushing, pelletize, packaging get product.

Present invention additionally comprises such feature：The manufacture method of described Candida utilis seed liquor is：Take 5 ° of B é wheats Bud juice, sterilizes 15-20 minutes at 121 DEG C, is cooled to 25-30 DEG C, is inoculated with Candida utilis, in 25-30 DEG C, 150-200rpm Under conditions of shaking table culture 15-18 hour.

The high protein fermentation feedstuff of the present invention is, with flaxseed meal as primary raw material, to be obtained through the step such as enzymolysis and fermentation 's.The high protein fermentation feedstuff of the present invention has the advantages that nutritious, protein content is high, good palatability.Further, since fermentation Before have passed through enzymolysis step, not only make the virose antinutritional factor of tool in flaxseed meal be decomposed release, improve edible Safety, also creates the nutrient substance with health-care effect such as γ-aminobutyric acid, aglycon flavone, increased fermentation of the present invention The health-care effect of feedstuff.

Specific embodiment

The strain Candida utilis CICC32834 that the present invention is adopted is purchased and is managed in Chinese industrial Microbiological Culture Collection Center.

Take 5 ° of B é beerworts, 121 DEG C sterilize 15 minutes, be cooled to 28 DEG C, be inoculated with Candida utilis, 28 DEG C, Under conditions of 180rpm, shaking table culture obtains final product Candida utilis seed liquor in 16 hours.

Sprout brown rice is crushed into obtain germination brown rice powder, the flaxseed meal of certain mass is weighed, flaxseed meal quality 15% is added Germination brown rice powder, add the ammonium sulfate of flaxseed meal quality 7%, be mixed with water, make material moisture control 53% Solid medium is first digested 4.5 hours under the conditions of 44 DEG C by solid medium, then is warming up to 58 DEG C of enzymolysis 2.5 hours, so After be warming up to 70 DEG C digest 45 minutes, finally under the conditions of 121 DEG C sterilize 30 minutes, be cooled to 28 DEG C, by Candida utilis Seed liquor and active dry yeast are inoculated in above-mentioned solid medium by 10% and 0.1% inoculum concentration respectively, are put down after mix homogeneously It is taped against on tray, ferments 75 hours in relative humidity 86%, the growth cabinet of 28 DEG C of temperature, then Jing cold drying, powder Broken, pelletize, packaging get product.
