| Abstract: | The conditions of extracting protein from walnut were studied and optimized by acid alkali mention.Based on the isoelectric precipitation of walnut protein,the influences the ratio of walnut protein to the assisted extraction methods,pH value,temperature,time,and solid-liquid ratio on the extraction were investigated.The results of test showed that the isoelectric precipitation of walnut protein was 4.6;under the ultrasonic wave process condition,the liquid-solid ratio was 1:90,extraction temperature 55 ℃,lye pH 7.5,extraction time 70 min.the extraction rate of walnut protein was 55.83%. |
