摘要
研究了孜然挥发油微胶囊的生产工艺。选用β-环糊精作壁材,采用四因素三水平响应面设计确定最佳微胶囊生产条件。实验确定孜然挥发油微胶囊化的最佳工艺:芯材与壁材比为6∶7、进风温度210℃、可溶性固形物含量30%、均质压力25MPa,在此条件下挥发油的理论包埋率为86.7%。
In this study,production conditions for Cuminum cyminum essential oil microcapsulation are investigated using response surface methodology.β-Cyclodextrin was used as wall material.A Box-Benhnken central composite Design with four independent variables： core material/wall material,inlet temperature,soluble solid content,and homogenization pressure was used to study the response variables（encapsulation percentage）.Data analysis showed that optimal parameters of Cuminum cyminum essential oil microcapsulation are as followings： core material/wall material 6∶7,inlet temperature 210 ℃,soluble solid content 30%,and homogenization pressure 25 MPa.At this optimum condition,encapsulation percentage of Cuminum cyminum essential oil microcapsulation was 86.7%.
