摘　　要：鱼油微胶囊的壁材对鱼油的抗氧化性有重要的作用,为优化罗非鱼油微胶囊的壁材组成,对明胶、蔗糖、黄原胶等壁材配比进行了响应面设计,以罗非鱼油微胶囊产品的包埋率作为主要评价指标。研究发现,罗非鱼油微胶囊适宜壁材配方为:蔗糖13·50%,明胶5·10%,黄原胶0·31%,鱼油6·50%。由此壁材配方得到的微胶囊化罗非鱼油产品的包埋率达到89·16%,产品经加速氧化15d后POV值仅为对照的二分之一,抗氧化性明显。产品水分含量低,色泽洁白,溶解性好,溶解后呈牛奶状,有较好的鱼油味。The optimized components for wall materials of tilapia oil microcapsule by response surface method were studied in this article.The effects of gelatin,sucrose,xanthan gum and fish oil on microcapsule were discussed by analyzing microcapsule efficiency as the index.The results showed that the optimum parameters were as following ： gelatin 5.10%, sucrose 13.50%, xanthan gum 0.31 % and fish oil 6.50%.The microcapsule efficiency of the product was 89.16%.The POV of the product was only a half of the blank control, so the product had obvious oxidative stability.The product also had low moisture content,white color and better solubility.The solution of the product was milk-white and had fish oil flavor.
