摘　　要：以阿拉伯胶、β-环糊精为壁材原料,以亚麻油为芯材,通过喷雾干燥法制备亚麻油微胶囊。以单因素试验选择固形物浓度、阿拉伯胶与β-环糊精质量比、壁材与芯材质量比、搅拌时间、进风温度的适当取值范围,以包埋率为考察指标,使用响应面Box-Behnken设计方案对生产进行工艺优化,获得最优工艺参数为进风温度179℃、阿拉伯胶与β-环糊精质量比6∶1、固形物浓度26%、搅拌时间36 min、壁材与芯材质量比5∶1。在此工艺条件下亚麻油微胶囊包埋率为97.82%。高温贮藏试验表明,微胶囊包埋对亚麻油成分具有较好地稳定作用,可有效地抑制亚麻油的品质退化。冷藏试验结果表明,鸡肉经亚麻油微胶囊复合液涂膜处理后,在8 d的贮藏过程中,可维持较好的品质。The linseed oil microcapsules were prepared by the spray drying method using Arabic gum andβ-cyclodextrin as the wall material and linseed oil as the core material.The appropriate value ranges of solid concentration,mass ratio of Arabic gum toβ-cyclodextrin,mass ratio of wall material to core material,stirring time,and air inlet temperature were selected by single factor test.Taking the embedding rate as the investigation index,the production process was optimized by using the response surface Box-Behnken design scheme.The optimal process parameters were as follows:air inlet temperature 179℃,Arabic gum toβ-cyclodextrin ratio 6∶1,solid concentration 26%,stirring time 36 min,and wall material to core material ratio 5∶1.Under these conditions,the embedding rate of linseed oil microcapsules was 97.82%.High temperature storage test showed that microencapsulation could stabilize the change of linseed oil composition and effectively inhibit the quality degradation of linseed oil.The results of cold storage test showed that the fresh quality of chicken meat could be maintained well during 8 d of storage after being coated with linseed oil microcapsule compound solution.
