Response Surface Model Optimization of Oligosaccharide Extraction from Coix Seed by Ultrasonic-assisted Technology
摘要
Abstract
Response surface analysis methodology (RSM) was applied in this paper to optimize the ultrasonic-assisted extraction (UAE) of oligosaccharides from Coix seed (CSO).On the basis of single factor experiment,liquid-solid ratio,ultrasonic temperature,ultrasonic time and ultrasonic power were chosen as the random factors.Established the mathematical model by Box-Behnken test and then analyzed the impact degree of the three technological parameters on the response of CSO to optimized the processing parameters.The result showed that the order of parameters on the yield of CSO was as follows:ultrasonic power ＞ extraction time ＞ liquid-solid ratio.The optimal technical condition for CSO:ultrasonic temperature was 70 ℃,liquid-solid ratio was 33∶1 mL/g,ultrasonic time was 27 min and ultrasonic power was 450 W.Under this condition the extraction rate was 0.94％,which is close to the predicted value of 0.98％.It indicated that using the response surface methodology to optimize the yield of CSO is reasonable.关键词
