摘要
对测定粮食脂肪酸值的方法进行改进,采用石油醚取代苯溶剂进行浸提,改进法其RSD为0.9%,P>0.05,绝对误差<0.5%,相对偏差最高为3.6%,改进后的方法能有效防止有毒苯对人体的伤害,方法更显得方便与实用,测定值更接近真实值。
this article mainly discussed the improvement of the way that the amout of fatty acid value in grain properly meaoured. In thy improved way petroleum echer,, replaing benzene solvent is used to draw ;and RSD=0.9%, p〉0.05,absolute error 〈0.5%; the biggest relative error=3.6%.The improved way that the measured amount is more close is the actual amount and alieh is concidey more pratical and convenient, can effectively prevent the harm poisonous benzene does to the human body.
