本文研究偏最小二乘法同时测定稻米中的直链和支链淀粉含量的实验条件,可以不用预先测定总淀粉,无需控伽每个样品总淀粉使之相同,结果直链和支链淀粉的平均回收率分别为99.70%和102.06%,测定结果和国家标准的方法基本相符,而具有简便快速、准确、可靠,适于大批量样品分析的特点。 In this paper, partial least squares method for simultaneous determination of linear and amylopectin in rice experimental conditions, without the need for pre-determination of total starch, without the need to control the total starch each sample to make the same, the results of the average linear and amylopectin The recoveries were 99.70% and 102.06%, respectively. The results were in good agreement with those of national standards. However, the method was simple, rapid, accurate, reliable and suitable for high-volume sample analysis.
