【摘要】：在以脱脂米糠为原料提取肌醇的工艺中,用离子交换树脂吸附植酸,再用Na OH溶液洗脱,得到植酸钠溶液,采用植酸酶阳离子激活提高酶活后催化植酸钠水解,获得肌醇溶液。对肌醇溶液采用离子交换树脂净化,既可淡化产品颜色,又能有效去除各种杂质离子。研究表明,用阶梯式阳、阴、阴、混合树脂柱进行离子交换,净化效果理想,树脂再生易行。交换液的流速为300~400 m L/min。
[Abstract]:In the process of extracting inositol from defatted rice bran, phytic acid was adsorbed by ion exchange resin, then eluted with NaOH solution to obtain sodium phytate solution. Inositol solution was obtained. The ion exchange resin was used to purify the inositol solution, which can not only desalinate the color of the product, but also effectively remove all kinds of impurity ions. The purification effect is ideal and the resin regeneration is easy. The flow rate of the exchange solution is 300 m / L / min.
