| 摘 要： | 建立了一种简单、重复性好的超声波破壁提油测定粉末油脂中油脂过氧化值的新方法。超声波破壁法提油其提油率可达65%左右,可满足测定要求。同时超声波破壁操作对油脂过氧化值测定没有影响。该方法操作简便、重现性好、结果准确可靠,可用于生产企业和用户对微胶囊粉末油脂的过氧化值的测定。

| Abstract: | A new method was built to determine the POV of powdered oils by broking the wall with ultrasonic and then extracting the oil to determine the POV.By broking the wall of powdered oils with ultrasonic,the oil extraction efficiency yield was 65%,which met the need of determining POV.Furthermore,the treatment method with ultrasonic did not affect the POV of oil.The established method was simple,rapid and reliable. |
