Abstract

The invention belongs to the technical field of rapeseed protein extraction, and particularly relates to an extraction process of rapeseed protein. The extraction process disclosed by the invention comprises the following steps: peeling rapeseeds, separating kernels and peels, softening rapeseed kernels, squeezing the softened rapeseed kernels, and crushing the cake blanks subjected to squeezing treatment so as to obtain rapeseed meal; then putting rapeseed meal into a container, adding petroleum ether for degreasing therapeseed, filtering the mixture, putting degreased rapeseed meal into thecontainer, adding the mixed solution, soaking for 2-4h, performing irradiation treatment, and filtering the mixture; adding a hydrochloric acid aqueous solution into irradiated precipitates, performing ultrasonic treatment, and filtering the mixture; adding an ethanol aqueous solution into the obtained mixture A, performing ultrasonic treatment and filtering the mixture; adding water into the mixture B, adjusting the pH value and heating the mixture B; finally, adding a compound enzyme, performing enzymolysis, enzyme deactivation and filtration, adding activated carbon into enzymatic hydrolysate, and performing suction filtration, concentrating filtrate, and freeze drying. The method is high in extraction rate, anti-nutritional ingredients can be effectively removed, and the digestibilityof the obtained rapeseed protein is high.

Description

technical field [0001] The invention belongs to the technical field of rapeseed protein extraction, and in particular relates to a process for extracting rapeseed protein. Background technique [0002] Rapeseed is one of the main oil crops in my country, and rapeseed oil is one of the important edible vegetable oils in my country. However, a large amount of rapeseed meal remains after the rapeseed passes through the oil extraction process. As the main by-product of rapeseed oil extraction, rapeseed meal (cake) is rich in natural plant protein and is an important source of animal feed protein. At the same time, it is rich in other active ingredients and is also an important industrial raw material. Due to the presence of anti-nutritional components in rapeseed meal, such as phytic acid and glucosinolates, etc., it will have adverse effects on animal palatability or growth and development, which greatly limits the application of rapeseed meal in feed. [0003] At present, th...
