Title: Optimization of primary extraction of oligosaccharidesfrom defatted peanut cake
Abstract: To make more comprehensive use of defatted peanut cake,response surface methodology was applied to study the effect of extraction temperature(x1),extraction time(x2)and ethanol concentration(x3) on the production of ethanol soluble sugar from defatted peanut flour.Regression analysis was performed on the data obtained.Extraction temperature of 51℃,extraction time of 1.5h and ethanol concentration of 57%(V/V)were thought to be optimal for soluble saccharides extraction from defatted peanut cake,the optimal saccharides yield can be achieved to 12.67%.The Mw determined by HPLC was mainly from 360 to 5000Da.It mainly contained sucrose,also had small quantity of raffinose,stachyose,seminose,fructose.
