Abstract
The invention discloses a preparation method of feather protein powder. The method comprises the following steps of mixing feather raw material with bran, after stewing the mixture at high temperature and high pressure, destroying the chemical bond such as disulfide bond in the feather keratin by utilizing the instantaneous pressure releasing impacting effect so as to improve the crude protein content in the feather powder and the pepsin digestion rate; through the lactobacillus anaerobic solid fermentation effect, the ratio of original lacked amino acid (lysine, tryptophan and the like) in the feather can be increased, the content of different amino acid in the feather powder can be balanced, the quality feather protein powder with high value can be produced, the content of the crude protein can reach up to 90 percent, and the pepsin digestion rate can reach up to 95 percent. The feather is processed by adopting the method to prepare the protein powder, so that the keratin structure inside the feather can be effectively destroyed within a short time, energy conservation and environmental friendliness can be realized, and no recycling process is needed, and the preparation method is an ideal processing technology.
Description
Technical field
The invention belongs to field of feed processing, relate to and a kind ofly in steam blasting mode, process the method that feather becomes albumen powder.
Background technology
It is desirable feed protein source that poultry (chicken, duck, goose) feather is rich in the multiple essential amino acid of animal, but is not effectively utilized.The processing technology of poultry feather discarded object mainly contains autoclaving Hydrolyze method, acid and alkali hydrolysis method, extrusion method, enzymatic isolation method and microbe fermentation method at present.
Autoclaving Hydrolyze method is to use high pressure high temperature vapor to continue boiling feather a period of time, destroys the formed disulfide bond of cystine in feather protein, and its steam pressure at least just can reach the object of destroying chemical bond in feather protein more than 138 kPa.To be that Process is simple easily control the feature of the method, but have lot of energy, and long-time heating can destroy some heat sensitivity amino acid, reduces the shortcomings such as some amino acid whose digestibility.Acid and alkali hydrolysis method is that feather is immersed in certain density acid (hydrochloric acid, phosphoric acid) or alkali (NaOH), and heating hydrolysis until easily break with have gentle hands, after this neutralizes, dry or pull out and with clear water, wash into neutrally afterwards, then dehydrates and makes finished product.The disulfide bond of this destroyed keratoprotein, makes feather protein resolve into the state that can digest and assimilate.Acid and alkali hydrolysis method is compared autoclaving Hydrolyze method can make feather more easy to digest, but equipment requirement is high, cost is large and in and time generate a large amount of salt, product hygroscopicity is strengthened, and easily causes feed to contain salinity and too much suppress growth of animal.Enzymatic isolation method and microbe fermentation method are to utilize special strain fermentation feather, or add protease effect feather to be changed into the feather protein of hydrolysis, but this kind of method and technology content and equipment investment are high, are difficult for large production.The feather meal albumen made from said method in addition all has the problem of amino acid imbalance as protein source in feed, wherein lysine equal size is too low, has limited the application of feather meal on feed.
Patent (200910170082.3) discloses a kind of feather albumen powder and preparation method thereof, first feather is washed, is dried and cutting pretreatment, then adopt the quick-fried technology of vapour to carry out the quick-fried processing of effective vapour to feather, destroy the stable space structure of feather keratin, carry out again enzymolysis processing, make its little peptide and the amino acid that become solubility, thereby improve the Pepsin digestibility of feather protein, its biological value is greatly improved.In feather meal, crude protein content is up to more than 90%, and external stomach cardia digestibility reaches more than 88%.This invention need to be to washing, be dried and cutting pretreatment, the quick-fried enzymolysis processing of carrying out again of vapour, and complex production process, the process-cycle is long.
We are in conjunction with for many years at research and development, the knowhow in gas phase blasting technique field, use up-to-date advanced technology independent research to go out gas phase blaster of new generation and apply to feather albumen powder preparation, feather raw material and wheat bran are mixed, utilize the percussion of HTHP boiling moment release of pressure, the chemical bonds such as disulfide bond in feather keratin are destroyed, to improve crude protein content and the Pepsin digestibility in feather meal.Be aided with again the effect of Bacillus acidi lactici anaerobic solid-state fermentation, improve the ratio of original lack amino acid (lysine, tryptophan etc.) in feather, various amino acid whose content ratios in balance feather meal, the high-quality feather albumen powder of generation high value.
Summary of the invention
The preparation method who the object of this invention is to provide a kind of feather albumen powder, the method adopts gas phase explosion to replace chemical treatment, enzyme to process, and solves the technical matters that feather is prepared this key of albumen powder and the necessary butchering fowl offal treatment solving.
Technical scheme of the present invention is as follows:
The preparation method of a kind of feather albumen powder provided by the invention, it comprises the following steps: will regulate the chicken feather of water content to put into gas phase explosion retort, with certain pressure intensity and temperature dimension, press after certain hour, moment is released into normal pressure by reaction mass, product is dry in drying box, product is successively inoculated bacillus licheniformis, lactobacillus-fermented certain hour after pulverizing, and obtains feather albumen powder.
In the present invention, before gas phase explosion treatment, at 10-250g feather, add the water of 10%-90%, soak 2-24h.
In the present invention, gas phase explosion treatment is under the condition of air pressure 0.5-1.6MPa, to maintain pressure 1-20min.
In the present invention, the aeration-drying 10-48h under the condition of temperature 30-55 ℃ of the feather after gas phase explosion.
In the present invention, the feather meal after aeration-drying regulates water content at 30-50%, and 30-40 ℃ of fermentation 12-96h of inoculation bacillus licheniformis, inoculates lactic acid bacteria anaerobic fermentation 24-144h, saves backup.
Beneficial effect of the present invention is:
(1) amplification of gas phase blasting gear and technique completes, and can meet industrialization quantity-produced needs; The gas phase explosion treatment that completes feather only needs 20min, convenient and swift, significantly shortens the production cycle; Only need 0.5 ton of steam, with low cost pollution-free;
(2) project of the present invention is introduced gas phase explosion (steam blasting) technology the machining field of poultry feather, the proposition of novelty this new technology of gas phase explosion of poultry feather, not only cost-saving, and can produce the finished product of high digestibility, for feed industry provides the protein raw materials of high-quality.
