摘要: 近年来潲水油(或地沟油)事件时常出现,为寻找鉴别潲水油的方法,防止潲水油回流到食用油市场,本文采集到的潲水油、煎炸老油及合格食用植物油的理化指标与国家规定的食用油标准进行对比,同时比较三种油的水分含量,发现潲水油及煎炸老油的酸价远远高于国家食用油最高允许值,因此,可作为辨别潲水油、煎炸老油与合格食用植物油的理化指标。

Abstract: Recently,some people used the Hogwash fat to make food.It will do a lot of harm to the people that eat the food.To look for the method that can distinguish the Hogwash fat from good edible vegetable oils and to prevent it from coming backto the edible oils market, we compare the Hogwash fat and frying oils with state standard.We also compare the concentration ofwater of the Hogwash fat ,frying oils and retail oils that buy from supermarket. We found that the acid value(AV)of the Hogwashfat and frying oils are much higher than the state standard.So the AV can be a characteristic that can distinguish the Hogwash fatand frying oils from good edible vegetable oils.

Key words: Hogwash fat, acid value(AV), peroxid value(POV), physical and chemical target
