摘要
以羟丙基-β-环糊精为壁材,制备了羟丙基-β-环糊精/虾青素包含物,并对其稳定性进行了研究。热重/差热联用分析表明,复合物的形成将虾青素的热分解开始温度至少提高了40℃,达到290℃左右。光热稳定性实验显示,包埋有利于提高虾青素在环境中的稳定性,并且具有很好的缓释效果。经羟丙基-β-环糊精包埋后,复合物比原虾青素具有更高的稳定性。
The astaxanthin/hydroxypropyl-β- cyclodextrin complex was prepared using hydroxypropyl-β- cyclodextrin as wall material.The stability of the complex was investigated. Hermogravimetry/differential thermal analysis indicated that the formation of complex improved the thermal decomposition start temperature by at least 40℃,reached up to 290℃.The light/thermal test showed that inclusion increased the stability of astaxanthin, and regulated the release of astaxanthin.The stability of astaxanthin/hydroxypropyl-β-cyclodextrin complex was higher than parent astaxanthin.
