该文主要以大豆分离蛋白和麦芽糊精为复合壁材，单硬脂酸甘油酯和蔗糖酯为复合乳化剂，制备含油量为30%以上棕榈油微胶囊，并对制备微胶囊化工艺条件进行优化。结果表明：在复合乳化剂添加量为2.5%（单甘脂∶蔗糖酯=3∶7）、剪切乳化时间6 min、乳化温度为70℃、壁材∶芯材=1.5∶1、进风温度为180℃的条件下，可以获得包埋率为82.3%、含油量为32.9%的微胶囊。
해문주요이대두분리단백화맥아호정위복합벽재，단경지산감유지화자당지위복합유화제，제비함유량위30%이상종려유미효낭，병대제비미효낭화공예조건진행우화。결과표명：재복합유화제첨가량위2.5%（단감지∶자당지=3∶7）、전절유화시간6 min、유화온도위70℃、벽재∶심재=1.5∶1、진풍온도위180℃적조건하，가이획득포매솔위82.3%、함유량위32.9%적미효낭。
In this paper,the microencapsulated powder of palm oil which thecontent of oil was beyond 30% was prepared using soybean protein isolation and maltodextrin as wall materials at sucrose ester and monoglyceride as compound emulsifier. The technological condition of microcapsule was discussed. The result indicates that the optimum the proportion of compound emulsifier was 2.5%(the ratio of monoglyceride and sucrose ester was 3∶7),the time of shear emulsification was 6 min,the temperature of emulsify was 70℃,the ratio of wall to core 1.5∶1. At the optimum the embedding rate of microencapsule could reached 82.3%and the content of palm oil was 32.9%.
