响应面优化鸭肉香精微胶囊化制备工艺的研究

摘要

Take gelatin and gum arabic as wall material;use complex coacervation method for embed-ding duck essence,take embedding rate as response value and use response surface methodology to op-timize the main factors that affect the embedding rate:wall material concentration,ratio of the core material and wall material,pH.It is found that the optimal parameters for preparing duck essence mi-croencapsulation by complex coacervation method are:when the wall material concentration is 2.23%,the ratio of core material and wall material is 1.19,pH is 4.32,the maximum embedding rate of duck essence microencapsulation is 81.61%,which is basically consistent with the theoretical value.%以明胶、阿拉伯胶作壁材，利用复凝聚法对鸭肉香精进行包埋，以包埋率为响应值，运用响应面分析法优化影响包埋率的主要因素：壁材浓度、芯壁比和pH。研究发现，复凝聚法制备鸭肉香精微胶囊的最佳工艺参数为：在壁材浓度为2．23％，芯壁比为1．19，pH 为4．32的条件下，鸭肉香精微胶囊化包埋率最大值为81．61％，与理论值基本相符。
