摘　　要：市面阿胶糕类产品保质期多为1年。主要原因是经过长时间储存后,其表面及内部水分随储存时间的延长而蒸发,进而导致阿胶糕失水、变硬,难以下咽,同时,阿胶糕原料油脂含量较高,长时间储存易出现脂肪哈败现象。为解决这一问题,从阿胶糕保水性、抗氧化性2个方面展开研究,确定一种长效期阿胶糕的最佳制备工艺。试验对常用水分保持剂进行选择确定,通过单因素试验筛选聚葡萄糖与SPI的质量分数、聚葡萄糖与SPI的比例、抗氧化剂维生素C添加量,通过加速试验验证制得的阿胶糕保质期可达2年。最佳配方为工艺阿胶20%、黑芝麻20%、核桃仁15%、黄酒20%、冰糖8%、聚葡萄糖14.4%、SPI 1.6%、维生素C 1%。Most of donkey-hide gelatin(E’jiao)cake products on the market have a shelf life of one year.The main reason is that after long-term storage,the surface and internal moisture evaporate,which in turn causes donkey-hide gelatin(E’jiao)cake to lose water,become hard,and difficult to swallow.Donkey-hide gelatin(E’jiao)cake has a high oil content,and it is easy to deteriorate fat after long-term storage.In order to solve the problem,carrying out research on the water retention and antioxidant properties,the optimal preparation process of one kind of donkey-hide gelatin(E’jiao)cake for long shelf life was determined.The moisture retention agents were selected and determined.The mass fraction of polydextrose and SPI,the ratio of polydextrose to SPI,and the amount of antioxidant vitamin C were screened by single factor experiment.The accelerated test verified that the shelf life of the donkey-hide gelatin(E’jiao)cake prepared by the research could reach two years.The optimal process was to prepare donkey-hide gelatin(E’jiao)cake with 20%donkey-hide gelatin(E’jiao),20%black sesame,15%walnut,20%rice wine,8%rock sugar,14.4%polydextrose,1.6%SPI,and 1%vitamin C.
