Antioxidative peptide was prepared from peanut meal by fermentation with Bacillus subtilis,and DA201-C macroporous resin was used to desalt the permeate obtained by ultrafiltration of fermentation broth so as to get better quality antioxidative peptide.Dynamic adsorption of macroporous resin showed that the adsorption capacity was influenced by the concentration of samples and the flow rate,and the best parameter was 6 mg/mL and 1 mL/min,respectively.After adsorption,the macroporous resin was eluted by etha... |
