Abstract:

Several macroporous adsorption resins were applied to desalination of oat protein hydrolysate. The experiments of static adsorption and desorption showed that macroporous adsorption resin DA201-CⅡhad the highest adsorption-desorption capability and to oat peptides among 8 resins. In further study, the optimal desalination conditions of oat protein hydrolysate with the resin DA201-CⅡwere confirmed as follows: pH of oat protein hydrolysate 4.0, concentration of oat peptides 39 mg/ml, flow rate of water washing 1 BV/h, and desorption rate of 75% ethanol 1.5 ml/min. Under these conditions, the desaltion rate reached about 93.4%, and the recovery of oat peptides was about 72.3%.
