为评估一种脱酚棉籽粕新工艺技术的可行性,对工艺过程中各阶段产品的关键成分（粗蛋白质、游离棉酚、赖氨酸和蛋氨酸等）进行了测定。以脱壳棉仁为原料,经低温压榨和己烷浸出制得脱脂粕,再经甲醇浸出制得脱酚棉籽粕。结果表明,脱酚棉籽粕保留了大部分赖氨酸和蛋氨酸,而粗蛋白质和游离棉酚含量分别为50.15%和0.008 2%;棉仁低温压榨结合己烷及甲醇浸出工艺是一种很有前景的优质脱酚棉籽粕生产技术。

The contents of key components including the protein,free gossypol,lysine acid and methionine acid were determined at each process stage so as to evaluate the technical feasibility of a novel process for degossypol cottonseed meal production.The dehulled cottonseed was pressed at low temperature followed by extraction with hexane solvent to produce defatted meal,then the defatted meal was extracted by methanol to remove gossypol.The obtained degossypol cottonseed meal retained most of lysine acid and methionine acid,while contained the 50.15% protein and 0.008 2% free gossypol.The results sugg...
