| 摘 要： | 为获得新型的微胶囊粉末油脂乳化剂和壁材,以蜡质玉米淀粉为原料,采用湿法制备辛烯基琥珀酸淀粉酯,再经普鲁兰酶水解,获得辛烯基琥珀酸直链淀粉酯,并研究了辛烯基琥珀酸直链淀粉酯的性质及其在微胶囊粉末油脂中的应用。结果表明,辛烯基琥珀酸淀粉酯经普鲁兰酶水解后,乳化性略有降低;制备的辛烯基琥珀酸直链淀粉酯具有低粘度和良好的成膜性;作为壁材和主要乳化剂制备微胶囊粉末油脂时,包埋率较高,无渗漏、破裂现象,表面油含量低,包埋效果良好;微胶囊复原乳状液对盐酸、柠檬酸及金属离子的耐受性好,在24h内未出现分层现象。

| Abstract: | To obtain new emulsifier and wall material used in oil microcapsule,octenyl succinic anhydride starch(OSA-Starch) was prepared with waxy corn starch by wet method,and hydrolyzed by Promozyme,then OSA-Amylase was obtained.Some properties and application of OSA-Amylase were studied.The results showed that the emulsibility and viscosity of OSA-Amylase decreased,while the film forming property increased.The embedding of oil encapsulated with OSA-Amylase was fine,and the recover emulsion of microcapsule was stab... |
