摘　　要：对照分析了光照与避光、有氧与真空包装/充氮包装、常温与高温/冷藏/冷冻等不同条件对DHA微胶囊的稳定性的影响。结果表明:光照、有氧条件、高温等贮藏条件均促进DHA微胶囊的氧化;其中影响DHA微胶囊稳定性的关键因素是隔绝氧气与否。将DHA微胶囊用锡箔袋真空包装,室温下放置8周,POV值仅由初始值1.7meq/kg增加到3.01meq/kg,DHA保留率降为94.0%,DHA微胶囊的稳定性较好。This article studied the influences of storage conditions,such as illumination or lucifuge,aerobic packaging or vacuum packaging/nitrogen gas packing,normal temperature or high temperature/refrigeration/freeze,on the stability of DHA microcapsules.The results showed that light,aerobic and high temperature conditions would promote oxidization of DHA microcapsule,in which the key factor influencing the stability of DHA microcapsule is whether isolated oxygen or not.A storage test was carried out by vacuum packaging the DHA microcapsules with foil bag,stored at room temperature for eight weeks,the results showed that the POV value increased from the initial value 1.7 meq/kg to the 3.0l meq/kg,the DHA reserved rate reduced to 94.0%,and the stability of DHA microcapsules was great.
