CONTENT
　　Soybean protein concentrate and soy protein isolate are important food raw materials,which are used to improve the nutritional value and appearance quality of food.After extracting soybean oil at room temperature and removing solvent at low temperature,low denaturation soybean meal can be obtained,which can further produce protein concentrate and protein isolate products.Soybean low temperature meal equipment can effectively prevent the thermal denaturation of soybean protein and provide the precondition for the further utilization of soybean protein.

　　Generally,butane solvent or the mixture of propane and butane is used in low temperature subcritical extraction of soybean oil.Compared with the crude oil extracted from hexane,the crude oil contains higher content of vitamin E and phytosterol,lower content of phospholipids,and the crude oil is lighter and white in color.The main process parameters are:
　　Thickness of soybean embryo:0.3mm
　　Moisture of blastocyst:5%~12%
　　Material solution ratio:1:1~1:1.5
　　Extraction pressure:≤0.5Mpa
　　Extraction temperature:20℃~40℃
　　Counter-current extraction times:4 times
　　Residual oil of meal:≤1%
