玉米多孔淀粉在制备姜油微胶囊化粉末中的应用

摘要

以玉米多孔淀粉吸附姜油制成的粉末作为芯材，再以β-环糊精为壁材包埋芯材。该方法制取姜油微胶囊的最佳工艺条件是：姜油：玉米多孔淀粉=1∶3（质量比），壁材：芯材=0.25∶1（质量比），包埋率达85.3%，微胶囊产率为90.1%。加速贮藏试验中，微胶囊姜油过氧化值及感官特性的变化均优粉末姜油。%The powder made of corn porous starch adsorption the ginger oil was the core material , and then used theβ-cyclodextrin as wall material to embed the core material. The optimum process conditions were:the ginger oil: Corn porous starch = 1 ∶ 3, core material: wall material = 0.25 ∶ 1, embedding rate 85.3 %, microcapsule yield 90.1%. Accelerated storage test , peroxide value and sensory characteristics of the micro-capsules of ginger oil changes are excellent powder ginger oil.
