摘要:花生香精含有多种易挥发成分,被广泛应用于食品中。本课题旨在研制出稳定的以BCA为壁材的微胶囊花生香精,以保证花生香精的特征香气和缓慢释放的稳定性。实验首先通过不断调配得到花生香精,然后进行微胶囊花生香精的制备,并考察了制备工艺中乳化剂的量、花生香精的量、壁材的量等因素对微胶囊稳定性的影响,得出乳化剂的量为2.5%,香精量为3%,pH=2.0,BCA的量为200ul,滴加速度为20s/d,转速为1000r/min,乳化时间20min,反应时间2h的条件下得到的体系最佳,并对最终稳定体系进行表征。22468 毕业论文关键词:花生香精;微胶囊;稳定性
Synthesis and characterization of polybutylcyanoacrylate - encapsulated peanut flavour microcapsule
Abstract: Peanut flavour, containing many kinds of volatile compound, is widely applied in the food industry. This study is aimed to synthesize and characterize a kind of stable polybutylcyanoacrylate-encapsulated peanut microcapsule, to make sure the duration of the characteristic aroma can be extended to a much longer period. In this study, peanut flavour was prepared with suitable formulation, then polybutylcyanoacrylate was used to encapsulate peanut flavour to form microcapsules. The stability of microcapsule depends upon the content of emulsifiers, peanut flavour and BCA, and the optimal formulation was achieved and characterized with 2.5% emulsifiers, 3% peanut flavour, 200ul BCA at pH 2.0, 1000 r/min rotating speed, 20 min emulsifying time and 2h reaction time.
Keywords: Peanut flavour; microcapsule; Stability
