摘要: 采用冷热风变温干燥技术,优化蓝莓和苹果重组果浆干燥工艺,生产高品质重组蜜饯果糕。通过单因素和正交试验优化变温干燥工艺参数,分析制备成品的感官评价、超微结构和质构特性。结果表明,蓝莓苹果重组蜜饯果糕的最佳干燥工艺为装盘厚度6 mm,前期热风烘烤温度70 ℃,热风烘烤时长7 h,后期30 ℃冷风抽湿至产品最终含水量小于15%。在此干燥工艺条件下获得的蓝莓苹果重组蜜饯果糕酸甜可口,果香浓郁,有较高的韧性和低粘附性,超微结构显示其组织光滑紧密,感官评分较高,理化指标及微生物指标均符合国家标准。

Abstract: The cold and hot air temperature drying technology was adopted to optimize the drying process of blueberry and apple pulp to produce high quality reconstituted fruit cake. The parameters of the variable temperature drying process were determined by single factor and orthogonal experiments, and the sensory evaluation, ultrastructure and texture characteristics of the finished product were analyzed. The results showed that the best drying process of blueberry-apple reconstituted fruit cake was 6 mm thickness, 70 ℃, 7 h in the early hot air baking, and 30 ℃ in the late cold air to the final water content of the product was less than 15%. The blueberry-apple reconstituted fruit cake obtained under the dry process condition was sweet and sour, fruity and rich, with higher toughness and not sticky to teeth. The ultrastructure showed that the tissue was smooth and compact, the sensory score was high. The physical and chemical indicators and microbial indicators were in line with the national standards.
