Description

一种西瓜缓释香精及其制备方法
技术领域
本发明属于化工领域,涉及一种西瓜缓释香精的制备方法,具体涉及一种以γ-环糊精为壁材、西瓜香精为芯材的缓释香精的制备方法。
背景技术
环糊精分子略呈锥形的圆环,具有外缘亲水而内腔疏水的特殊结构,使其能包埋范围广泛的客体分子,例如药物、精油、抗氧化剂、甚至惰性气体,通过疏水性相互作用力、范德华力、氢键等形成主客体包合物。而西瓜香精因其具有令人愉快的香气,能够有效掩盖异味,在食品、医药、化妆品等方面都具有广泛的应用。鉴于环糊精有上述优势,通过环糊精包埋香精能有效提高香精的溶解性,保护其挥发性成分,控制释放,提高利用率。
其中研究较多的环糊精分别是含有6、7、8个葡萄糖单元分子的α-环糊精、β-环糊精、γ-环糊精。α-环糊精含有的空腔偏小,大分子的客体无法进入空腔内,通常只能包埋较小的客体分子,应用范围较小。目前使用范围最为广泛的β-环糊精,因其本身固有的低水溶性限制了它的应用范围。而本发明所使用的γ-环糊精具有空腔大,水溶性好,负载率高的特性,能与香精中的大分子芳香化合物形成稳定的包合物。
发明内容
本发明所要解决的技术问题是:香精中大分子芳香化合物无法被包埋的问题;其次是环糊精包埋香精负载率低的问题。
为了解决上述技术问题,本发明提供了一种西瓜缓释香精,其特征在于,所述西瓜缓释香精为片状,该片状结构的壁材为γ-环糊精,芯材为西瓜香精。
优选地,所述西瓜缓释香精的原料包括以下以质量百分比计的组份:
Figure BDA0002538622660000011
更优选地,所述的乳化剂为非离子型表面活性剂吐温20。
本发明还提供了上述西瓜缓释香精的制备方法,其特征在于,包括以下步骤:
步骤1):将γ-环糊精溶解于去离子水中,搅拌直至γ-环糊精全部溶解,形成水相;
步骤2):将西瓜香精溶解于乳化剂中,搅拌形成油相;
步骤3):向步骤1)所得的水相中加入步骤2)所得的油相,持续搅拌,使油相与水相充分混合,形成均一稳定的乳液,即西瓜缓释香精。
优选地,所述步骤1)、步骤2)中搅拌的速度均为500r/min;步骤3)中搅拌的速度为300r/min。
采用本发明的方法所得到的西瓜缓释香精粒径分布均匀,其步骤简单可行,缓释效果良好。经动态激光光散射仪测试。
附图说明
图1为实施例1制备的西瓜缓释香精的扫描电镜图;
