摘　　要：以脱脂米糠为原料提取肌醇,用离子交换树脂吸附植酸,再用NaOH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,水解液最后用CaCO3溶液破坏水解平衡的原理辅助水解,从而制得得率高达11.5%的肌醇。In the inositol extraction process with defatted rice bran as raw material,through the absorption of phytic acid by ion exchange resin and the elution with caustic NaOH,the sodium phytate solution was gained.Then the use of phytase cation could improve the enzyme’s activity and catalyze the hydrolysis,the adding of CaCO3 solution in the hydrolyzate would assist the hydrolysis by destroying the hydrolysis balance,therefore,the inositol yield was up to 11.5%.
