the applicant finds in the course of the invention that: the rich peptide feed has wide sources, and soybean protein, corn protein and the like can be used as bioactive peptide raw materials and are prepared by protease enzymolysis or biological fermentation. However, no research on processing clostridium ethanolate protein into polypeptide exists at present, and the current production process of clostridium ethanolate protein powder is as follows: the mycoprotein is prepared by solid-liquid separation and drying. The solution containing bacteria is obtained from the residual water in the tower bottom of the upstream distillation process, and is concentrated by centrifugal separation, and after the concentration of the bacteria is properly increased, the clostridium ethanolate protein powder is directly obtained by spray drying. Compared with protein, the active peptide has the advantages of strong solubility, high emulsibility, quick absorption, high absorptivity and the like, and also has multiple functions of resisting bacteria and viruses, regulating immunity, regulating flavor, resisting oxidation, promoting growth and the like.
According to an exemplary embodiment of the present invention, there is provided a method for preparing a feed additive, the method including:
s1, obtaining a clostridium ethanolate protein solution;
in some embodiments, the obtaining of the clostridium ethanolate protein solution specifically comprises:
s1.1, pretreating industrial coal gas to obtain fermentation gas;
s1.2, fermenting the fermentation gas to obtain fermented liquor;
s1.3, distilling the fermented mash to obtain tower still residual distilled water;
s1.4, concentrating the residual distilled water in the tower kettle to obtain clostridium autoethanolate protein solution;
in some embodiments, the mass concentration of Clostridium ethanolicum protein in the Clostridium ethanolicum protein solution is between 80g/L and 190 g/L.
S2, treating the clostridium ethanolate protein solution to obtain a polypeptide-containing solution; wherein the treatment comprises treatment for preparing peptide by enzyme hydrolysis, treatment for preparing peptide by acid hydrolysis, treatment for preparing peptide by alkali hydrolysis and treatment for preparing peptide by fermentation;
in some embodiments, every 1m of the enzymatic hydrolysis peptization process3The addition amount of the enzyme of the clostridium ethanolate protein solution is 0.5Kg-1.5 Kg.
Calculating according to the concentration of protein substrate in protein solution, enzyme activity, and controlling each enzyme by experiment1m3The addition amount of the enzyme of the clostridium ethanolate protein solution is 0.5Kg-1.5Kg, the adverse effect of overlarge addition amount is to increase the production cost, the adverse effect of undersize is to reduce the enzymolysis degree, and the peptide content in the obtained product is lower.
In some embodiments, the temperature of the enzymatic hydrolysis peptization process is 50 ℃ to 80 ℃, and the time of the enzymatic hydrolysis peptization process is 0.5h to 2 h.
The reason that the temperature is controlled to be 50-80 ℃ and the time is controlled to be 0.5-2 h is that: the material temperature and the optimal temperature of the used enzyme are within the range of 50-80 ℃, the optimal enzymolysis time is 0.5-2 h, and the adverse effect of overlarge value is as follows: increasing the production costs, too small an adverse effect is: the enzymolysis degree is low, and the peptide content in the obtained product is low.
If the novel protease has high enzyme activity, wider optimal temperature and optimal pH range and the like, the addition amount, temperature and enzymolysis time of the enzyme can be adjusted according to the optimal conditions.
Specifically, protease, preferably acidic protease, is added to the clostridium ethanolate protein solution after solid-liquid separation and concentration. The feed liquid added with the protease is fully and uniformly mixed with the raw material liquid through a uniformly mixing device, a pipeline mixer is preferably selected, the protease and the raw material liquid enter an enzymolysis process, and the enzymolysis is fully carried out through a pipeline with preferable heat preservation and time delay. The process can be replaced by other related technologies in the industry, such as acid and alkali hydrolysis of protein to prepare peptide, fermentation to prepare peptide, and enzymolysis, and neutral protease, alkaline protease, compound protease, etc. can also be used, and the enzymolysis process can be replaced by a heat-preserving container, etc.
S3, drying the polypeptide-containing solution to obtain a feed additive;
specifically, after enzymolysis for a certain time, the feed liquid enters the storage tank and is fully stirred again, and then enters a drying system for drying through a pumping, preferably spray drying. And (3) drying to obtain a product: a novel peptide-containing feed additive.
The method takes industrial gas as a main raw material and produces byproducts in the process of producing ethanol by fermentation of clostridium ethanolate. The method specifically comprises the steps of taking residual distilled water of a distillation tower kettle containing clostridium ethanolate thalli as a raw material liquid for production, and increasing the solid content of the material liquid through solid-liquid separation and concentration.
In some embodiments, the same can be achieved by changing the clostridium ethanolicum proteolytic sequence or hydrolysis method, for example: (1) the original clostridium ethanolate protein powder is diluted by a proper amount by adding water, heated and sterilized, cooled to the optimal enzymolysis temperature, added with protease for enzymolysis for a proper time, and dried to prepare the novel peptide-containing feed and feed additive. (2) The residual water of the clostridium ethanolicum thalli is added with a proper amount of acid or alkali, continuous hydrolysis is carried out at medium-high temperature, the efficiency of the subsequent solid-liquid separation process is improved due to protein denaturation, and finally peptide-containing feed and feed additive are produced by adjusting pH and drying. The peptide is easy to dissolve in water, the centrifugal clear liquid contains more soluble peptide, and the product of the invention is obtained after concentration (the concentration mode which is common in the industry such as evaporation concentration and the like) and drying, wherein the peptide content is high, but the production cost is high. (3) The method comprises the steps of hydrolyzing partial mycoprotein of clostridium ethanolate into peptide by using residual distilled water of a clostridium thallus tower kettle and adopting a protease or acid-base hydrolysis mode, performing centrifugal separation, concentrating and drying to obtain the product of the invention, wherein the peptide content is high, but the production cost is high, and the centrifugal clear liquid contains more soluble peptides because the peptide is easily dissolved in water.
In some embodiments, fermentation can be used to process clostridium ethanolate proteins into polypeptides, and in particular, residual water containing clostridium ethanolate bacteria or clostridium ethanolate protein powder is used as a nitrogen source to provide peptide-containing feed and feed additives for fermentation of polypeptide-producing bacteria.
In some embodiments, the novel peptide-containing feed additive can be produced by mixing and matching the processes of preparing peptide by enzyme hydrolysis, preparing peptide by acid hydrolysis, preparing peptide by alkali hydrolysis and preparing peptide by fermentation.
