Study on extracting protein from peanut by aqueous enzymatic extraction

Protein was extracted from peanut.The influencing factors such as varieties of enzymes,solid-liquid ratio,the amount of enzyme,pH value,temperature and time were studied.The optimum process conditions were as follows:Alcalase as enzyme preparation,solid-liquid ratio 1:6,the amount of enzyme 6%(E/S),alkaline extraction of pH 8.5,temperature 65℃,enzyme reaction time 150min.Under these conditions,the protein yield of 8 different variety of peanut were different,that was bai sha the highest and hua yu 16 the lowest.
