摘要
本论文对紫薯味核桃仁加工工艺进行了优化。在单因素试验的基础上,选择紫薯粉用量、白砂糖用量、烘烤温度、烘烤时间四个因素,采用正交试验法对紫薯味核桃仁的关键工艺进行优化。结果显示紫薯味核桃仁最佳工艺参数为:紫薯粉用量为20g,白砂糖用量为15g,加入100g的水进行熬煮,待料液浓稠时,加入60g核桃仁裹料后烘烤,烘烤温度为115℃,烘烤时间为75min。在此工艺条件下,生产的紫薯味核桃仁风味最佳,且酸价较低。
Optimized the technologies of Purple sweet potato flavor Walnuts by Orthogonal test. Based on single factor experiments, the amount of purple sweet potato flour, the amount of sugar, baking temperature and baking time was selected as influencing factors. The results indicated that the optimum parameters was: the amount of purple sweet potato flour 20g, the amount of white granulated sugar 15g, drying temperature 115℃, drying time 75min.
