抗氧化剂BHT微胶囊化产品超微结构的测定

用扫描电子显微镜(SEM)研究抗氧化剂二丁基羟基甲苯(BHT)微胶囊化产品的超微结构。观察了喷雾干燥法不同壁材组成和工艺条件下制作的微胶囊化产品的表面结构和内部结构,同时考察了喷雾干燥进风温度对微胶囊化产品膜结构的影响。结果表明,不同壁材组成和工艺条件下制作的微胶囊化产品的超微结构有较大差异,合适的壁材组成和工艺条件有利于提高产品质量,同时喷雾干燥进风温度对微胶囊化产品的结构有很大影响,从而也影响到产品的质量。微胶囊化产品超微结构的研究为分析影响产品质量的因素提供了重要依据。

Study on Superstructure of Microencapsulated Antioxidant BHT

Scanning electron microscopy(SEM) was applied to study the superstructure of microencapsulated star butylated hydroxytoluene(BHT) manufactured by various preparation techniques.The results showed that preparation techniques had significant effects on the structure of microencapsulated products,and thus affected the qualities of products.The research about superstructure of BHT could provide information for analyses on the quality of microencapsulate products.
