摘要
旨在产出高质量棉籽蛋白并对脱酚液中的棉子糖进行回收利用,对棉籽蛋白脱酚工艺及棉子糖的制备工艺进行了研究.结果表明:控制棉仁粉末度在 21.44%左右,脱酚溶剂甲醇体积分数80%～90%,料液比在 1∶0.56～1∶0.63 之间,不仅可以达到最佳的棉籽蛋白脱酚效果,还可稳定采出棉子糖含量在3%以上的脱酚液;控制一次浓缩挥发性组分在 85%左右,絮凝时pH为 8～9,脱色时pH为 5～6,二次浓缩挥发性组分为 45%左右,所提取的棉子糖粗品中棉子糖含量可达到85%,重结晶后棉子糖含量可达到98%以上.
Abstract
In order to produce high quality cottonseed protein and recycle the raffinose in the degossypol solution,the degossypol process of cottonseed protein and the preparation process of raffinose were studied.The results showed that under the conditions of cottonseed kernel powder degree about 21.44%,volume fraction of methanol(degossypol solvent)80%-90%,and the ratio of material to solvent 1∶0.56-1∶0.63,it could not only achieve the best degossypol effect of cottonseed protein,but also could stably produce the degossypol solution with the raffinose content over 3%.When volatile constituent in the primary concentration was controlled to about 85%,the pH was 8-9 during flocculation,the pH was 5-6 during decolorization,and volatile constituent in the secondary concentration was about 45%,the raffinose content in the extracted crude product could reach 85%,and the content of raffinose after recrystallization could reach more than 98%.
