【摘要】 以盐酸、尿素为提取剂,脱脂米糠为原料,采用微波浸提、离子交换和微波水解从米糠中提取肌醇,并探讨其工艺条件。结果表明(1)微波浸提植酸较佳的工艺条件:功率为80 W,浸提时间5min,浸提温度55℃,中和方式二步法,离子交换流量(10~15)mL/min;(2)微波水解植酸制备肌醇的较佳工艺条件:V(甘油)∶V(水)=1∶1,植酸浓度0.5 mol/L,盐酸浓度0.05 mol/L,微波功率为120 W,辐射时间80 min。微波法从米糠中提取肌醇能显著缩短提取时间、降低成本,提高肌醇得率,并且具有操作简单,快速方便,环保友好等特点。

【Abstract】 Using the extraction with hydrochloric aid and urea as extractant and rice bran as raw material,inositol was extracted by microwave assistance extraction,ion exchange and microwave radiation hydrolysis.The optimum coditions of the extraction and hydrolysis by microwave assistance extraction were investigated.The result shows that(1)The optimum conditions for phytic acid extraction are as follows: microwave power 80 W,extraction time 5 min,extraction temperature 55 ℃, extraction for neutr-alization is completed by two grade,ionic exchange flux(10~15) mL/min;(2) The optimum conditions for inositol are as follows: the volume ratio of the glycerin and water 1∶1,phytic acid concentration 0.5 mol/L,hydrochloric acid concentration 0.05 mol/L,microwave power 120 W,the irradiation time 80 min.Inositol extraction by microwave radiation can short the extraction time,reduce cost,improve yield.This method also possesses the advantages of quick,simple,and environment friendly operation.
