摘　　要：为了获得高强度液芯微胶囊,采用中心组合设计研究了氯化钙、瓜尔豆胶、海藻酸钠、壳聚糖浓度,以及成膜时间对液芯微胶囊机械强度的影响,建立了上述各参数与液芯微胶囊机械强度之间的回归模型,获得最优的制备条件为瓜尔豆胶2.14 g/L、氯化钙2.56%、海藻酸钠0.69 g/L、壳聚糖2.96 g/L、成膜时间34 min。To obtain high - intensity liquid - core microcapsules, central composite design was used to study the effects of the concentration of CaC12, guar gum, sodium alginate and chitosan, and the film - forming time on the intensity of liquid - core microcapsules. Regression models were established between the above parameters and the mechanical intensity, The optimum conditions for the microcapsules were CaC12 2. 56%, guar gum 2. 14 g/L, sodium alginate 0. 69g/L, chitosan 2. 96g/L and the film - forming time 34min.
