【摘要】 本文对由脱脂米糠经酸浸取碱中和的菲丁生产工艺进行了详细的条件试验，并研究了采用离子交换树脂提取菲丁的条件。酸浸取碱中和菲丁提取率达９０％～９３％，离子交换法菲丁提取率稍低，为８８％，但菲丁中糖类、蛋白质含量低，利于进一步制备肌醇。更多还原

【Abstract】 The condition experiments of manufacture phytin from defatted rice bran using acid-extract and alkali-neutraligation method are studied,the extract rate is 90%～ 93 %.The conditions of manufacture of phytin by ion-exchange resins are also studied,its extract rato is 88 % ,but the content of suger and protein is lower,so it is more suitable for inositol preparing.更多还原
