【摘要】 本文研究了玉米蛋白粉脱臭的三种方法,即NaClO脱臭法、吸附剂脱臭法和复合纤维脱臭法,其中复合纤维脱臭法效果最好。选择脱脂羊毛、姜纤维、麦麸纤维、蔗渣纤维、魔芋纤维、甜菜纤维六因素做 L 27(313)正交实验,并且考虑前三者交互作用。实验结果表明,因素较好的搭配为A3B3C3D1E2F2,但是从经济角度出发取A3B3C3D1E1F1为最佳方案,即脱脂羊毛为1．5％,姜纤维为1．5％,麦麸纤维为1．5％,蔗渣纤维为 0．5％,魔芋纤维为0．5％,甜菜纤维为0．5％。更多还原

【Abstract】 Three methods, sodium hypochlorite, adsorbent, and compound fiber, were studied for de - odour of maize protein powder. The result shows the compound fiber method is the best. An orthogonal design L27(313) was taken to optimize the compound fiber forming with six factors, i. e. , degrease wool, ginger fiber, bran fiber, bagasse fiber, konjac fiber, and beat fiber; meanwhile, the interaction between degrease wool, ginger fiber and bran fiber was taken into account. The results show that the optimum level combination is A3B3C3D1E2F2; in view of saving, it is A3B3C3D1E1F1, i. e. , degrease wool 1. 5% , ginger fiber 1. 5% , bran fiber 1. 5% , bagasse fiber 0. 5% , konjac fiber 0.5% and beat fiber 0.5%.更多还原
