Abstract

The invention discloses a method for synchronously extracting rice bran oil and rice bran protein from rice bran. The method comprises the steps that the rice bran is smashed and screened after being cleaned and sorted, then water is sprayed to wet the rice bran, and the rice bran stands to obtain a material A; the material A is subjected to microwave treatment to obtain a material B; the material B is squeezed twice to obtain crude rice bran oil C and rice bran residues D, and then the crude rice bran oil C is refined to obtain the rice bran oil; the rice bran protein in the rice bran residues D is extracted through an enzymolysis method. Two times of squeezing comprises primary squeezing and secondary squeezing. According to the specific process of primary squeezing, the temperature of the material B is raised to 60 DEG C to 65 DEG C, the material stands for 30 min to 40 min, and then primary squeezing is carried out to obtain a solid material N and a liquid material H. According to the specific process of secondary squeezing, after the temperature of the solid material N is raised to 60 DEG C to 65 DEG C, puffing treatment is carried out, and then secondary squeezing is carried out to obtain the rice bran residues D and a liquid material K. The method is low in cost, and the yield of the obtained rice bran oil and rice bran protein is high.

Description

technical field [0001] The invention relates to the technical field of agricultural resource extraction, in particular to a method for synchronously extracting rice bran oil and rice bran protein from rice bran. Background technique [0002] my country is the largest rice producer in the world. Rice bran is the main by-product produced during rice processing, and rice bran is rich in nutrients such as oil and protein, and is an important agricultural resource. At present, rice bran is mainly used for oil extraction, and the comprehensive utilization rate is not high. The rice bran protein in rice bran must have a balanced amino acid composition, has extremely high nutritional value, and has low allergenicity, and is suitable for infants and special populations. How to further utilize rice bran to increase added value has become the focus of industry research. Contents of the invention [0003] Based on the technical problems in the background technology, the present inve...
