摘　　要：以高温米糠粕为原料,研究不同工艺顺序对米糠粕综合利用时各活性物质提取效果的影响。采用1mol/L盐酸作为提取溶剂,室温下提取1 h,可将植酸钙得率提高5.2%,大大提高了提取效率。综合利用工艺中,通过对各活性物质提取顺序的研究,确定了适宜高温米糠粕综合利用的工艺顺序为提取植酸钙→糖化酶除淀粉→提取蛋白质→提取多糖。此工艺顺序不仅最大程度避免了各活性物质间的相互影响,而且提高了蛋白质和多糖的质量。The effect of sequence of extraction process about comprehensive utilization on the extraction effect of active substances was studied with high temperature rice bran meal as raw material. Using 1 mogL hydrochloric acid as extraction solvent, extraction for 1 hour at room temperature, the phytic acid calcium yield could be increased by 5.2%, greatly improving the extraction efficiency. The suitable comprehensive utilization process sequence was determined by the study of extraction sequence about each active substance. The suitable sequence was extracting phytic acid calcium first, removing starch by glucoamylase second, extracting protein thirdly, and extracting polysaccharide finally. This process not only avoided the mutual influence of each active substance, but also improved the quality of protein and polysaccharide.
