Ultrasonic assisted in the extraction of protein from camellia seed meal was studied.According to the single factor experimen tions were ts, selecting the optimal ultrasound parameters based on the orthogonal experiment, and the optimal reaction condi- confirmed by orthogonal tests as follows:ratio of solid to liquid l:20(g/mL), pH 10,the ultrasonic temperature 50℃, the ultrasonic power 300W,the ultrasonic time 60min,and the extraction rate of camellia seed protein could reach 57.82%. And evaluating the sensory characteristics index and qu...
