Extracting protein from pine nut with ultrasonic-associated water was studied,affecting factors of extracting yield such as the ratio between material and liquid,extracting time,extracting temperature,ultrasonic frequency and ultrasonic time.On the basis of single factor test,extracting condition was optimized by PSA under the same technics,the best technics : the ratio between material and liquid 1:36,extracting time,127min extracting temperature 38℃,the protein extracting yield was 69.4%.
