Abstract:
Object To optimize the process for the recovery of soyasaponins from bean product waste. Methods Conditions for the recovery were studied by orthogonal design guided by the yield of soya-saponins as determined by UV absorbance. Results The most influential factor in the recovery by refluxing was the concentration of alcohol; while in the recovery by percolation the influential factors were in the order of concentration of ethyl alcohol, amount of alcohol used and the rate of percolation.Conclusion The optimal recovery process was found to be a single reflux with eight times of 60% alcohol for 2.5 h.
