Rape-seeds or rape-seed meal are relatively cheap, but valuable raw materials for the manufacture of protein concentrates and isolates which may be used as constituents of foodstuffs. The high content of crude fibres and also of thioglucosides leads to considerable difficulties in the development of techniques for the manufacture of high-grade protein preparations. To describe the procedure, certain production-technological properties of rape proteins are discussed, such as extraction parameters, coagulating conditions, processing temperature, amount of solvent, etc. On the basis of these data, the following techniques for the manufacture of rape protein products are presented: - protein concentration by means of the water diffusion method; - protein isolation with the aid of one or multi-stage extraction. Finally, the author reports of a fermenting procedure for the manufacture of protein biomass from coarse colza meal. Furthermore, he presents some data about the nutritional value of rape protein.
油菜籽或油菜籽粕是相对便宜但有价值的原材料，可用于制造浓缩蛋白和分离蛋白，这些蛋白可用作食品的成分。粗纤维和硫代葡萄糖苷的高含量给制造高档蛋白质制剂的技术开发带来了相当大的困难。为描述该过程，讨论了油菜蛋白的某些生产工艺特性，如提取参数、凝固条件、加工温度、溶剂量等。基于这些数据，介绍了以下制造油菜蛋白产品的技术： - 通过水扩散法浓缩蛋白质； - 通过单级或多级提取分离蛋白质。最后，作者报告了一种从粗油菜粕制造蛋白质生物质的发酵方法。此外，他还提供了一些关于油菜蛋白营养价值的数据。
