Method for producing efficient protein feed by feed enzymes cooperated with bacillus coagulans

Abstract

The invention discloses a method for producing efficient protein feed by feed enzymes cooperated with bacillus coagulans, and belongs to the field of biotechnology fermentation. The bacterium enzymes are used for treating bean meal in a cooperated way; the sterilization treatment on the bean meal is not needed; the facultative anaerobic and anaerobic fermentation are performed in the whole process; the energy consumption is low; the dry substance loss is low. The technical flow process operation is simple and convenient; the method is suitable for direct production and feeding in a culture plant and is also suitable for scaled production in a feed plant; in addition, the raw material cost is low; the method is suitable for industrial production. The fermented bean meal has high acid fragrance; the palatability is high; the pH is 3.2 to 4.5; the organic acid content is 2.8% or above; the acid dissolution protein is improved by 6.5 times or above through being compared with that before the fermentation; the soluble protein with the relative molecular weight within 500 is 60% or above; the urease activity is lower than 0.073U/g; the cotton seed sugar content is lower than 0.42 percent; the stachyose is lower than 0.035 percent; the spore number of the bacillus coagulans is 2.0*10<9>cfu/g or above.

Description

technical field [0001] The invention belongs to the field of biotechnology fermentation, and in particular relates to a method for producing high-efficiency protein feed by cooperating with bacillus coagulans with feed enzymes. Background technique [0002] The absorption of macromolecular proteins by animals is obviously not as good as the absorption of small molecular polypeptides and amino acids. At the same time, there are many anti-nutritional factors in plant protein raw materials, such as urease, trypsin inhibitor, phytic acid, lectin, lipoxygenase and Soybean antigenic protein, etc. affect the digestion, absorption and metabolism of nutrients, and have adverse effects on the health and production performance of animals, thus restricting the more effective application of plant protein in poultry breeding. [0003] The current methods for producing high-efficiency biological protein feed mainly include protease hydrolysis and microbial degradation. [0004] The use of...
