摘要本试验旨在研究蒸汽爆破技术对棉籽粕中游离棉酚的脱毒效果。
Abstract: This experiment was conducted to study the detoxification of steam explosion technology on free gossypol content of cottonseed meal.
在最佳脱色条件下，脱色率达到84%，且脱色液中检测不到游离棉酚的存在。
The decoloring ratio was about 84% under the optimum conditions, and the free gossypol couldn't be determined in the decolored solution.
但由于含有游离棉酚等有毒成分，在配合饲料和食用中的应用受到了严格限制。
Because of the venomous component, the cottonseed meal is controlled in the application for feed and edible.
用双液相溶剂（TPS）浸取棉仁可得到棉油、无毒饼粕及富含游离棉酚（FG）的甲醇相。
High-level cottonseed oil, gossypol-free cottonseed meal and methanol phase abundant in free gossypol (FG) could be obtained by the leaching process with a two-liquid phase solvent (TPS) system.
试验结果表明：复合发酵可极显著（P<0.01）地降低棉籽饼底物游离棉酚含量，脱毒率为91.64%；
The experiment showed that the mixed culture fermentation could decrease FG content in fermented CSC significantly(P<0.01) and the detoxification efficiency was up to 91.64%.
异丙醇浸出的棉籽油不含游离棉酚和黄曲霉毒素，棉籽饼粕中游离棉酚残留0.013%，黄曲霉毒素残留0.0002%。
The cotton seed oil extracted by isopropyl alcohol did not comprised free cotton hydroxybenzene and aflatoxin, there were 0.013% free cotton hydroxybenzene and 0.0002% aflatoxin in the meal.
但其中的游离棉酚(FG)会沉积于鸡蛋中，恶化蛋品质，严重影响鸡蛋的可接受性，并可能危害人体健康；同时也限制了棉籽粕在家禽饲粮中的用量。
But free gossypol (FG) seriously affects the acceptability of the egg, and even further endangers human health, as well as seriously lowers the application of cottonseed meal in layer diets.
