The production conditions of peanut protein concentrate from defatted peanut protein powder by alcohol extraction were optimized by single factor experiment and orthogonal experiment and verified by scale - up experiment. The results showed that the optimal production conditions were obtained as fol-lows: volume fraction of alcohol 65% , ratio of material to liquid 1: 8, extraction temperature 60 ℃, ex-traction time 40 min, extraction times three. Under the optimal conditions, the protein content and nitro-gen solubility index (NSI) of the peanut protein concentrate were 72% and 42% respectively. Further-more, an enlarged alcohol leached process was performed at a dose of 100 g under the optimal conditions, and the protein content and NSI of the peanut protein concentrate were 70% and 40% respectively.
