维生素 A 强化食用油的稳定性研究

Stability of edible oil fortified with V_A

在正常储存条件下储存维生素A强化食用油，检测其品质变化情况，发现用不透明容器包装的食用油，其维生素A含量均可达到18个月的保质期要求，在储存24个月后，其维生素A含量是相同条件下透明包装和半透明包装样品的2．1～2．8倍；而应用透明包装和半透明包装的维生素A强化油则不能有效地保证在保质期内维生素A含量的要求。

The stability of edible oil fortified with vitamin A under normal storage conditions was studied. The results showed that the vitamin A quantity was within the demand of national standard after stored 24 months under normal storage conditions packaged with untransparent materials,2.1 - 2.8 times the ones packaged with transparent and half-transparent materials. While the vitamin A quantity was much lower than the minimum quantity of the national standard packaged with transparent and half-transparent materials. Thus, untransparent package is necessary for vitamin A fortified oil.
