Abstract

In this paper,we separated the protein components 7S,11S and olesion from the soybean protein extract by three-step acid precipitation,compared the contents of lipids in the protein components of two kinds of low-temperature soybean meal,and analyzed the residual content of lipids in the low-temperature soybean meal and the effect of the lipids on the protein solubility in the low-temperature soybean meal.The results indicated that the residual lipids were disadvantageous for the protein extraction from the low-temperature soybean meal.
