1、喷雾干燥法制备水溶性核桃油粉末的工艺研究［摘要］目的以超临界C02制备的核桃油为原料，首次用含我司制的蛋黄蛋白粉为壁材，制备水溶性核桃油粉末。方法主要分别考察两组壁材的搭配和配比。据核桃油包埋的情况，以确定壁材麦芽糊精、大豆分离蛋白的配比；及据核桃油包埋得率的结果，以确定壁材大豆分离蛋白、蛋黄蛋白粉的配比。综合上述两组结果，以确定壁材麦芽糊精、大豆分离蛋白和蛋黄蛋白粉的配比。釆用喷雾干燥包埋方法制备水溶性核桃油粉末。结果首次用含我司制的蛋黄蛋白粉为壁材，具体为麦芽糊精：蛋白粉=3:1,其中大豆分离蛋白：蛋黄蛋白粉=1:1,制

2、得的水溶性核桃油粉末成型和包埋效果好，质量甚至达到婴儿食品标准水平，同时提供宏量营养素，延长了保质期，方便携带，适合各种年龄段或需喂饲人士服用。结论喷雾干燥包埋技术采用含蛋黄蛋白粉为壁材制备水溶性油脂粉末，为功能性动植物油脂市场的开发提供了多元化。［关键词］喷雾干燥；水溶性油脂粉末；蛋黄蛋白粉；功能性动植物油脂［中图分类号］R201.1［文献标识码］A［文章编号］1674-472105-0097-04[Abstract]ObjectiveTopreparethewatersolublewalnutoilpowderusing
