摘要: 通过单因素试验及L9(3)4正交试验的色差测定分析,研究了在光照条件下柠檬酸、食用碱和食盐的添加对南瓜面条色泽的影响。结果表明:单独添加柠檬酸对南瓜面条制品的色泽无明显的增色作用,同时在光照条件下也无护色效果。食用碱和食盐的单独使用具有一定的增色作用和护色效果。正交试验各因素中,光照期是南瓜面条退色的最主要影响因素,柠檬酸和食用碱的同时添加对南瓜面条退色的影响较小。

Abstract: The effects of citric acid,sodium chloride and sodium carbonate adding on color-protection of pumpkin noodle were studied.The results of hue determination showed that only adding citric acid could not enhance the natural color of pumpkin noodle obviously and had no effect on the color-protection under the conditions of lighting.Among the factors of the orthogonal test,light period showed the most significance on decoloration of pumpkin noodle.Citric acid and sodium carbonate adding together exhibited little effects on the decoloration.
