作者认为已报道的酸败油脂中挥发性羰基化合物的分离方法如真空蒸馏法、水蒸气蒸馏法、吹入氮气法等,都存在着需要试样量多,分离方法复杂,操作时间长,不适用于日常工作的缺点。因此研究提出了简易测定法。蒸馏装置和具体方法如下: The authors believe that there have been many sample separation methods such as vacuum distillation, steam distillation and nitrogen blowing, which have been reported in the volatile fatty compounds of rancid fat, complicated separation methods, long operating time, not suitable Shortcomings in daily work. Therefore, the study proposed a simple assay. Distillation equipment and specific methods are as follows:
