摘要: The objective of this work is to study on the preparation of peanut protein peptide by lactobacillus solid state fermentation method and to provide a theoretical basis for further investigating peanut meal special protein material product. Results indicated that the soluble nitrogen concentration of peanut protein peptide could reach 70.92mg/ml, 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) and hydroxyl free radicals scavenging rates were 95.00% and 86.28%, respectively, under the following optimum conditions: addition of nutrient salt solution volume of 25ml, lactobacillus liquid volume of 5ml, temperature of 25.0 degrees C, and time of 72h. Peanut protein peptide had good antioxidant activities.
