Abstract

The invention discloses a pleurotus eryngii culture material prepared from rice bran as a raw material. The mixed culture material in a dry state comprises the following raw materials in percentage by weight: 10%-20% of miscellaneous wood chips, 35%-40% of rice bran meal, 12%-27% of bagasse, 16%-30% of wheat bran, 3%-8% of corn powder and 1%-5% of calcium carbonate; the pre-wetted mixed culture material has the water content of 65%+ / -1 and the pH value of 4-5; the rice bran meal is prepared by leaching out grease and removing a solvent from wet meal. According to the pleurotus eryngii culture material prepared from rice bran as the raw material, the production speed and color of pleurotus eryngii can be ensured, and the nutritional value of the pleurotus eryngii can be improved; meanwhile, the preparation process of the rice bran meal is simple and relatively low in energy consumption, a method for preparing low-denaturation rice bran meal by adopting a leaching process can be carried out at the normal temperature, and the obtained rice bran meal is low in denaturation rate and residual oil rate and high in protein content and nitrogen soluble index.

Description

technical field [0001] The invention relates to the field of preparation and reuse of rice bran meal, in particular to a compost for pleurotus eryngii cultivation using rice bran meal as a raw material. Background technique [0002] Rice bran is a low-cost, nutritious by-product of rice processing, containing about 15% to 17% protein, 16% to 18% fat, 30% to 40% dietary fiber, 8% to 12% ash and rich oryzanol , phytosterols, tocotrienols and other biologically active substances. [0003] The protein content of degreased rice bran meal can be as high as 18%. Rice bran protein is recognized as a high-quality vegetable protein and hypoallergenic protein. Its essential amino acid composition is balanced and reasonable, and it is very suitable as a nutritional food for infants and special populations. However, most of the rice bran meal can only be used as animal feed at present, which is a serious waste of resources; this is mainly because rice bran meal is a by-product of the pr...
