摘要
油菜饼粕中含有丰富的蛋白质,是一种潜在的植物蛋白资源。由于油菜饼粕中含有硫甙、芥酸、植酸等有毒或抗营养物质,限制了其推广应用,而长期以来技术与工艺的原因又致使产业化的开发一直停滞不前。为了实现菜籽浓缩饲用蛋白的工业化生产,该文介绍了一种利用水性溶剂脱毒的低成本方法,其成品中干基蛋白质含量≥60%,硫甙含量为5μmol/g,植酸与多酚的脱除率分别为52%和55%。在当前市场条件下,使用该方法生产线的静态投资回收期为1.5年。
Rapeseed meal is rich in protein. As a potential source of high quality protein suitable for consumption, rapeseed meal is limited in application and generalization because of many anti-nutritional materials, such as glucosinolate, phytic acid and mustard acid, etc. The industrialized development has been at a standstill due to the complex techniques and high producing costs. A detoxifying method with lower costs by aqueous solvent was presented in this paper. After detoxification, the protein concentrates contained more than 60%(d.b. %) protein and only 51μmol/g glucosinolates, the removal efficiency of phytic acid and polyphenols were 52% and 55%, respectively. At present, the static payback period of investment for the production line is about 1.5 years.
