以明胶、阿拉伯胶为壁材,采用复合凝聚法制备天然椰子油微胶囊。用TG酶作为固化剂,以包埋率为主要评价指标,采用单因素试验和正交试验对天然椰子油微胶囊制备工艺进行优化。重点探讨p H、壁材质量浓度、芯壁比、反应温度对天然椰子油微胶囊制备的影响,并分析天然椰子油微胶囊产品的基本性质。结果表明:天然椰子油微胶囊制备的最佳条件为p H 3.5、壁材质量浓度20 g/L、芯壁比2∶1、反应温度40℃,该条件下制备的天然椰子油微胶囊产品的水分含量(2.88±0.31)%、表面油含量(4.20±0.05)%、包埋率(93.75±0.28)%、平均粒径413μm。
【英文摘要】
With gelatin and arabic gum as wall materials,virgin coconut oil microcapsules were prepared by complex coacervation. With transglutaminase( TG) as cross-linking agent,and embedding rate as the main evaluation index,the preparation process of virgin coconut oil microcapsules were optimized by orthogonal experiment on the basis of single factor experiment. The effects of p H,mass concentration of wall material,ratio of core material to wall material and reaction temperature on the preparation of virgin cocon...
