不同储藏温度下植物油的品质劣变

Quality changes of vegetable oil in different storage temperature

探讨了 4种植物油的酸值和过氧化值随储存温度、储存时间的变化规律。试验表明 :储藏温度越高 ,储藏时间越长 ,过氧化值和酸值增加越大 ;在相同的储存条件下 ,植物油的品质劣变与自身的成分有关。

The rules of acid value, peroxide value of 4 kinds of vegetable oils changing with temperature and time are discussed. It is indicated that peroxide value and acid value increase with the increasing of temperature and time and the quality deterioration is relevant with the contents of vegetable oil.
