Abstract
The invention discloses a method for treating rice bran meal and a product thereof, wherein the content of anti-nutritional factors in the rice bran meal is reduced by extracting phytic acid and soluble non-starch polysaccharide, and crude calcium phytate, a feeding microecological regulator, rice bran polysaccharide and rice bran protein peptide are prepared. The beneficial effects of the invention are as follows: the process produces various high-added-value products while producing the rice bran meal with low anti-nutritional factors by comprehensively utilizing the rice bran meal, has no waste emission in the whole process, and truly realizes green and safe high-value application production of the rice bran meal.
Description
Technical Field
The invention relates to a deep processing and comprehensive utilization process of rice bran meal, in particular to a method for producing rice bran meal with low anti-nutritional factors by extracting phytic acid and soluble non-starch polysaccharide.
Background
In order to adapt to the new situation that the supply and demand of bulk feed raw materials are tight, the utilization efficiency of raw materials is improved, a novel daily ration formula structure is built based on national conditions, the promotion of corn and soybean meal reduction substitution is accelerated, and the development of unconventional feed resources becomes a hot spot of current research. The rice bran meal is a byproduct of rice processing, is rich in resources and low in price, contains higher nutritional ingredients, and can be used as one of raw materials for reducing and replacing corn and bean pulp. However, because the rice bran meal has higher content of non-starch polysaccharide, phytic acid and other anti-nutritional factors, the overhigh dosage often affects the digestion of the whole nutrients of the diet, so that the production performance of livestock and poultry is reduced, and the proportion is limited during application.
Phytic acid is an important anti-nutritional factor in rice bran meal, and the proportion is about 7%. Because phytic acid is relatively stable in nature, the phytic acid is difficult to damage by physical treatment methods such as heating and the like, and the corresponding enzyme system is not digested and degraded in animal bodies. At present, phytase is mainly added into feed to degrade phytic acid in animal bodies, and the feed has extremely wide application. However, the effect of enzyme preparations in vivo can only be assessed in reverse by the performance of the feeding test production performance. A meta-analysis by Rosenfelder-Kuon et al 2020 shows that with phytase addition, the average phosphorus digestibility of pigs was stabilized at 65% although the phytic acid recovery was low in the pig manure. Another study by this authors (2020) also showed that with high levels of phytase addition, pig full gut phosphorus digestibility was not more than 60%. Therefore, new ways to reduce the nutritional resistance of phytic acid are needed.
Non-starch polysaccharides are another important class of antinutritional factors in rice bran meal, and are classified into soluble non-starch polysaccharides and insoluble non-starch polysaccharides according to solubility. Among these, the soluble non-starch polysaccharide is rice bran polysaccharide having good functional properties in the food field. At present, a great deal of scientific researches at home and abroad have proved that rice bran polysaccharides have various biological activities, such as apoptosis and cell cycle blocking effects on various cancer cells; antibacterial, antiviral, and immunity regulating; reducing blood glucose and regulating sugar metabolism; radiation resistance, liver protection, etc. However, in the feed, the feed has the adverse effects of increasing the viscosity of chyme, increasing the value of harmful bacteria and the like, and becomes an anti-nutritional factor.
In the prior art, comprehensive utilization of the rice bran meal for removing the anti-nutritional factors in the rice bran meal is not reported yet.

The inventor designs the process carefully, and all the steps are closely connected and are buckled, so that the safe and green comprehensive development and utilization of rice bran meal are realized. The invention has the advantages that the phytic acid and the chelated metal ions thereof in the rice bran meal are extracted by adopting an acid leaching method, so that the ash content of the rice bran polysaccharide extracted subsequently can be reduced from more than 20% to less than 2%, and the purity of the polysaccharide is improved; in addition, the protein content in the rice bran polysaccharide can be reduced from more than 25% to less than 10% by combining the hydraulic oscillation with the enzymatic extraction, so that the purity of the polysaccharide is further improved. The invention also has the advantages that the protein separated from rice bran polysaccharide mainly exists in the form of peptide, so that a protein peptide product can be formed, and the conversion value-added benefit is further improved.
The order of acid leaching and soluble non-starch polysaccharide extraction cannot be changed, otherwise the ash content in the subsequently prepared polysaccharide product is too high, which reduces the polysaccharide purity.
Further, the pH range of the acid leaching in the step (1) is 3.6-3.9, and the value is lower than the pH range, so that the residual amount of the phytic acid in the rice bran meal with low anti-nutritional factors prepared later is more than 0.4%, and the phytic acid is not completely removed.
Further, in the step (4), the yield of the calcium phytate is 13-16%, and the yield of the phytic acid is more than 80%.
Further, in the step (5), after fermentation, the pH of the supernatant B is reduced from 7.5-7.6 to 3.8-4.2, and the beneficial bacteria content comprises lactobacillus: 4.0 to 8.3X10 7 CFU/g, streptococcus thermophilus: 1.2 to 3.5X10 7 CFU/g, bifidobacteria: 1.4 to 3.9X10 7 CFU/g. Can be used asIs added into feed for direct feeding.
Further, in the step (7), the rice bran meal with low anti-nutritional factors (calculated on a dry basis) has the phytic acid content less than 0.1%, the soluble non-starch polysaccharide content less than 0.7%, the fiber content of 60-62%, the starch content of 18-22% and the protein content of 15-19%.
Further, in the step (10), the yield of the rice bran polysaccharide is 6-8%, and the purity of the rice bran polysaccharide is more than 70%.
Further, in the step (11), the yield of the rice bran protein peptide is 7-9%, the protein content is more than 80%, and the small peptide with the protein content of less than 1000Da accounts for more than 30%.
In the above method, the principle of hydraulic oscillation is similar to cavitation of ultrasonic waves, but since the industrialized use of ultrasonic waves is limited, we find an alternative technology, and the method has the following advantages: 1. can be directly amplified for production; 2. the treatment time is short, and the extraction rate of polysaccharide is reduced by 0.4-1% after more than 25min in experiments, so that the oscillation time is controlled within 25 min; 3. the technology is supplemented with enzyme, so that the purity of the polysaccharide can be improved by more than 30%.
In summary, the invention has the advantages that four high added value products of calcium phytate, rice bran protein peptide, rice bran polysaccharide and liquid feeding microecological regulator are obtained while reducing the content of anti-nutritional factors in rice bran meal. Firstly, the acid leaching process of the invention reduces about 12% of ash content in rice bran meal to below 2%, about 7% of phytic acid to below 0.1%, and reduces ash content of rice bran polysaccharide extracted subsequently from above 20% to below 2%; secondly, the invention fully utilizes the supernatant after calcium phytate precipitation. The partial supernatant contains about 10% of sugar by mass of rice bran meal and about 8% of soluble protein in total protein of the rice bran meal, and the partial supernatant is used as a liquid feeding microecological regulator through a fermentation technology because of acid-base neutralization and also contains a part of salt to be directly discharged and pollute the environment, and a fermentation product with rich beneficial bacteria content can be obtained without adding carbon and nitrogen sources additionally; thirdly, simultaneously obtaining high-purity rice bran polysaccharide and rice bran protein peptide products with high small peptide content by hydraulic oscillation assisted with enzyme treatment; finally, the rice bran meal with low anti-nutritional factors obtained by the invention eliminates the anti-nutritional effect of the rice bran meal, retains most dietary fibers in the rice bran meal, has good health care function, and can be widely added into feeds. The invention not only makes full and effective use of various nutrition and health care components in the rice bran meal, but also has the advantages of short production period, high extraction rate, cost and energy consumption saving, simple operation, no waste discharge and realization of high-value application production of the rice bran meal.
