竹笋干无硫护色技术的研究

通过对竹笋无硫护色技术的研究,发现氯化锌不适合作为竹笋干的护色剂,其他较优效果的护色剂分别是0.1%柠檬酸,0.1%抗坏血酸,0.2%半胱氨酸,0.3%EDTA-2Na。在柠檬酸、EDTA-2Na、半胱氨酸的正交组合中,没有显著因素,且选取的正交组合0.2%柠檬酸+0.2%半胱氨酸+0.3%EDTA-2Na的护色效果还不如单一护色剂0.3%EDTA-2Na的效果。最优的护色工艺条件是0.3%EDTA-2Na。

Study on the Anti-browning Technology for Dried Bamboo Shoot Slices without Sulfur Dioxide

In this paper,the anti-browning technology without sulfur dioxide of dried bamboo shoot slices were studied,and the results showed that the chloride zinc was not suitable for the anti-browning additive for dried bamboo shoot,among the other anti-browning additives,0.1% ascorbic acid,0.1%citric acid,0.2% cycteine and 0.3% EDTA-2na were good for the anti-browning effects. There was no prominent factor in the orthogonal experiment,and the effect of orthogonal combination were 0.2% citric acid,0.2%cycteine,0.3%...
