| Abstract: | Process parameters on cottonseed protein extracted by ammonia was researched with the single factor experiment.The process conditions,such as pH,extraction time,and extraction temperature were optimized by response surface method.The extraction ratio model then was built.It was predicted that the extraction ratio was 77.35 % when the pH was 11.78,extraction time was 3.36 h and the extraction temperature was 60 ℃.With the parallel experiment,the average extraction ratio of cottonseed protein was 77.53 % under the optimized conditions.The experiment results agrees well with the predicted results.It was shown that the model can accurately predict the extraction ratio and the influence on extraction ratio from the operation conditions. |
