研究了4种不同品质的菜籽油(冷榨菜籽毛油、热榨菜籽毛油、浸出一级菜籽油、压榨一级菜籽油)、3种容器(无色透明聚酯瓶、铁罐和陶罐)及3种光照条件(避光、自然光、直射灯光)下菜籽油的储存稳定性情况.室温条件(10～30℃)下间隔一定储存天数(10～15 d)测定样品的酸值和过氧化值,结果显示,光照是影响油脂储存稳定性的关键因素,油脂包装及储存要尽量采用不透光材料或避光储存;铁罐可用于储存毛油及精炼油,储存毛油时过氧化值升高幅度较精炼油要小;对成品小包装油,采用性质稳定的不透光的陶瓷材料包装是理想的选择.

In the case of 4 types of rapeseed oil(low-temperature pressed crude rapeseed oil,high-temperature pressed crude rapeseed oil,1st grade solvent extraction rapeseed oil,1st grade pressed rapeseed oil),3 containers(colorless and transparent PET bottle,iron cans,pottery) and 3 types of lighting environment(dark,natural light,direct lighting),the storage stability of rapeseed oil was studied.The acid value and peroxide value of samples at room temperature(10-30 ℃) were detected at interval storage days(10-15 d).The results showed that lighting was a key factor to affect oil storage stability,opaque packaging material should be used as far as possible,and the oil should be stored in dark environment;iron cans could be used to store crude oil and refined oil,but the increase rate of peroxide value of the crude oil was lower than that of the refined oil;the opaque ceramic material for small package of refined oil was an ideal choice.
