Abstract

The invention discloses a preparation method of biofermentation rice bran meal. The preparation method comprises the following steps of (1) raw material treatment: pulverizing and sterilizing rice bran meal; (2) inoculation and mixing: adding an enzyme preparation and water for temperature-controlled fermentation, wherein the mass percentage of the enzyme preparation is 0.01 percent to 0.03 percent; (3) temperature-controlled fermentation: mixing raw materials and a bacteria solution, and injecting the mixture into a fermentation pool for fermentation at the temperature of 30 DEG C to 45 DEG C for 2 to 3 days; (4) drying and pulverizing: performing drying at 60 DEG C to 80 DEG C, and obtaining the biofermentation rice bran meal after drying and pulverizing; and (5) packaging. The preparation method has the advantages that solid fermentation is adopted; the process is simple; and the cost is low. The prepared biofermentation rice bran meal has excellent attractant performance, high active polysaccharide and oligosaccharide content, excellent oxidation resistance, high small peptide content and nany probiotics, has the attractant function, and achieves the effects of promoting the probiotic flora breeding and improving the immunity.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a preparation method of biologically fermented rice bran meal. Background technique [0002] Rice bran meal is a kind of yellowish or yellow granular product obtained by puffing rice bran and separating most of the residual oil in it through leaching process. The annual output of rice bran meal in my country is 8-9 million tons, with wide sources and low cost. Low. Since rice bran meal contains a large amount of anti-nutritional factors, it has not been effectively utilized. At present, it is mainly used as primary raw material for feed industry. [0003] Rice bran meal is rich in nutrients, including protein, crude fat, non-starch polysaccharides, phosphorus and calcium elements, etc. But it also contains phytic acid at the same time. These ingredients affect the palatability or reduce the absorption of nutrients in the animal intestines. If it can be biodegrad...
