纸层析法测定菜油的脂肪酸组成,在我国低芥酸油菜育种中发挥了重要作用,该方法具有测定样品批量大的优点,但测定时间长达10小时以上,影响了大量样品和收购过程中的快速测定。为此,我们针对油的提取溶剂和酯化试剂的选择进行了进一步的试验,找到了快速提取和酯化反应的试剂,将原测定过程缩短到5小时以内,可以一次完成测定,并仍然保持 Determination of fatty acid composition of vegetable oil by paper chromatography has played an important role in the breeding of low erucic acid rapeseed in our country. The method has the advantages of large sample size determination, but the determination time is up to 10 hours, affecting a large number of samples and acquisition process Rapid determination. To this end, we conducted further tests on the choice of oil extraction solvents and esterification reagents, found reagents for rapid extraction and esterification reactions, shortened the original measurement process to less than 5 hours, performed the assay once, and still maintained
