目前,测定桕籽含油量常用“索氏抽提法”,测定结果虽然比较准确稳定,但分析周期长,操作环节多,试剂耗量大,劳动强度高,不能适应生产发展的需要。为解决这一问题,我们采用比重法测定桕籽含油量。经1年多的试验证明,优点较多,主要是:①取样多,代表性强,误差小,仅0.02-0.49%,而
At present, the determination of the seed oil content commonly used “Soxhlet extraction method”, although the measurement results are more accurate and stable, but the analysis cycle is long, the operation is more, the reagent consumption, labor intensity, can not meet the needs of production and development. In order to solve this problem, we use the method of proportioning to determine the seed oil content. After more than a year of testing proved that the advantages are more, mainly: ① sampling and more representative of the small error of only 0.02-0.49%, while
