Rape is a worldwide important oil-bearing crops, our country now rape planting area and rapeseed production (hereinafter referred to as rapeseed) are among the top of the world.Rapeseed is rich in fat and protein.Rapeseed protein has a balance of essential amino acids composition pattern, almost non-existent restrictive amino acids and is a kind of high-quality protein.Traditional palm oil mill (http://www.palmmill.com) in oil as the main purpose, because after high temperature treatment and the meal contains antinutritional factors can only be as forage and fertilizer.Protein in the human resources is increasingly lack today, improve the utilization value of rapeseed protein is of great significance.Emerging water enzyme legal oil technology can simultaneously extract oil and protein, but also can avoid using organic solvent to reduce air pollution.In k20 "double low" peeling rapeseed as the research object, adopts the water enzymatic extracted from rapeseed oil and biological active peptide, threshing station (http://www.palmmill.com/Products/prob/)the main research contents and results are as follows: the paper first studied the rapeseed endogenous thioglycoside enzyme and glucosinolates of damp and hot stability, determine the rapeseed boiling it in water for 5 min, as the degradation of glucosinolates enzyme inactivation and thioglycoside basic rate of 11.28%.Emulsified oil yield as examining index, and through the screening of different enzyme preparation and distribution of the experiment, finally determine the pectinase, cellulase, and beta glucan enzyme by 4:1:1 (v/v/v) compound with post-processing wet milling rapeseed pulp.Scanning electron microscopy (sem) the results intuitively reveal the cell wall polysaccharides compound enzyme hydrolyzing rapeseed pulp to release the mechanism of the oil.By single factor optimization experiment, optimal composite enzyme hydrolysis conditions were determined as follows: solid-liquid ratio 1:5, enzyme amount 3%...
