| 摘 要： | 采用传统的碱溶酸沉法提取了大豆粕及棉籽粕中大豆分离蛋白(SPI)及棉粕分离蛋白(CPI),并分别测定了棉籽粕,60目棉粕分离蛋白和80目棉粕分离蛋白中游离棉酚的含量,结果显示,60目及80目大豆粕中大豆分离蛋白的提取率分别为39.82%和44.95%(P<0.05),粗蛋白含量分别为81.07%和71.35%;60目及80目棉籽粕中棉粕分离蛋白的提取率分别为23.22%和35.39%(P<0.05),粗蛋白含量分别为76.03%和82.44%;棉籽粕、60目棉粕分离蛋白及80目棉粕分离蛋白中游离棉酚的含量分别为2182.54、522.79和503.87mg/kg(P<0.01)。综上所述,不同的粉碎粒度对大豆分离蛋白和棉粕分离蛋白的提取率有显著的影响,碱溶酸沉法显著降低了棉粕分离蛋白中游离棉酚的含量。

| Abstract: | Extract the SPI and CPI from soybean meal and cottonseed meal by traditional base-dissolve and acid-deposit, and determined the free gossypol of CPI. The results illustrated that the extraction of SPI from 60 or 80 meshes comminuted soybean meal were 39.82% and 44.95%(P<0.05), crude protein were 81.07% and 71.35%, respectively; the extraction of 60 or 80 meshes comminuted cottonseed meal were 23.22% and 35.39%(P<0.05), crude protein contents were 76.03% and 82.44%, respectirely; the free gossypol of cottons... |
