- Abstract:
- ?For improving the extraction efficiency of soluble polysaccharide from soybean meal and comprehensive utilization of soybean meal to a large extent，ultrasonic assistedextraction process of soluble soybean polysaccharides(SSPS)from low temperature soybean meal was studied.In order to improve the yield of SSPS，five independent variables which affected the SSPS yield，namely pH，ratio of raw material to water，ultrasonic time，ultrasonic temperature and ultrasonic power，were systematically investigated.Based on the singlefactor experiments result，orthogonal array design L16(54)was conducted to optimize the extraction condition of SPSS.The experiment results indicated that the SSPS yield of 8.15% was obtained under the optimum condition，namely pH2.0，ratio of material to water was 1∶4，ultrasonic time 20 min，ultrasonic temperature 40℃，and ultrasonic power of 200 W.
