摘　　要：采用脱脂乳粉为壁材,色拉油为芯材,通过正交实验,根据芯材的滞留率确定微胶囊化的最佳工艺条件。实验结果表明:采用脱脂乳粉、色拉油、2%吐温-20乳化剂水溶液和水的质量比为40:10:10:90,在8000r/min条件下乳化15min,之后在进风温度为140±2℃、出风温度为80±2℃条件下喷雾干燥,色拉油滞留率接近60%。可见,此种方法制作的微胶囊包埋效果较好。The skim milk powder was used as shell-material and salad oil as core-material. The optimal technological conditions of making the microcapsule were determined through orthogonal experiment in the paper. The results showed that the optimal conditions were as follows ： the mass ratio of skim milk powder, salad oil, the liquor of 2% Tween-20 and water was 40：10：10：90 and we should carry through the spray-drying when the stuff had emulsified 15min under the condition of 8000r/min with the inlet temperature of 140 ± 2℃ and the outlet temperature of 80 ± 2℃. In this way, we can have the microcapsule with good covering purpose and the retention rate of salad oil is close to 60%.
