摘要
目的:探究卵白蛋白(ovalbumin,OVA)、OVA-茶多酚(tea polyphenols,TP)、OVA-菊糖(inluin,IN)和OVA-IN-TP 4种壁材微胶囊对石榴籽油稳定性的影响。方法:使用喷雾干燥技术制备4种壁材的微胶囊,测定其包封率、溶解性等理化指标,采用激光粒度仪测定其粒度分布,使用荧光显微镜和扫描电子显微镜观察其微观结构,并对其抗氧化能力和贮藏稳定性进行研究。结果:以OVA-IN-TP为壁材的微胶囊粒径小且均一、表面光滑平整、无凹陷和孔洞,其对石榴籽油的包封率高达(94.52±3.19)%;贮藏稳定性实验结果表明,以OVA-IN-TP为壁材的微胶囊抗氧化能力显著提升(P<0.05),对光照、温度、湿度等极端环境抗性增强,且延缓石榴籽油氧化的能力最强。结论:实验为富含不饱和脂肪酸石榴籽油的开发利用提供了一种有效方法。
Objective:To investigate the effects of microencapsulation with different wall materials of ovalbumin(OVA),OVA-tea polyphenols(TP),OVA-inluin(IN)and OVA-IN-TP on the stability of pomegranate seed oil.Methods:Spray drying was used to prepare microcapsules,and the microencapsulation efficiency and solubility were measured.The particle size distribution was investigated by a laser particle size analyzer,the microstructure was observed by a fluorescence microscope and a scanning electron microscope,and the antioxidant capacity and storage stability were investigated.Results:The OVA-IN-TP microcapsules had small and uniform particle size and exhibited smooth surfaces without dents or holes,and the microencapsulation efficiency of pomegranate seed oil was up to(94.52±3.19)%.The storage stability test showed that the antioxidant capacity of microencapsulated pomegranate seed oil with OVA-IN-TP was significantly improved(P<0.05)with enhanced resistance to extreme environments such as light,temperature and humidity.Therefore,OVA-IN-TP had the strongest stability to delay the oxidation of microencapsulated pomegranate seed oil.To sum up,this study provides an effective way to develop and utilize pomegranate seed oil as a rich source of unsaturated fatty acids.
