摘要
通过单因素和正交设计试验,筛选胡萝卜颗粒在不同护色剂和不同干燥温度下的最佳护色组合.结果表明:单因素设计试验中,70℃干燥条件下1.0%氯化钠、0.2%植酸、0.4%氯化钙、0.6%柠檬酸优于其他干燥温度下不同浓度的护色剂,抗坏血酸、壳聚糖护色效果较差;正交试验中,筛选出最优复合护色剂为0.25%植酸+0.50%柠檬酸+0.30%氯化钙+1.5%氯化钠,复合护色剂护色后的褐变度较低,感官、营养保持较好.
In this paper, we carried out single factor experiments and orthogonal experiments to determine the optimum color protecting agent combination of carrot particles at different drying temperatures in the presence of different color protecting agents. The results showed that, in single factor experiments, the combination of 1% sodium chloride, 0.2% phytic acid, 0.4% calcium chloride and 0.6% citric acid was superior to other color protecting agents at the drying temperature, and ascorbic acid and chitosan had poor color protection effect; in orthogonal experiments, the optimum combination of color protecting agents was as follows : 0.25% phytic acid, 0.50% citric acid, 0.30% CaCl2 and 1.5% sodium chloride. The carrot particles added with the combination of color protecting agents had low browning degree and kept good sensory quality and high nutrition.
