本研究考察了柠檬酸、EDTA-2Na、Vc在二次杀菌软包装雷竹笋中的护色效果。通过监测高温或光照加强环境中雷竹笋色度的变化,优化了护色剂的配方。研究表明,添加浓度为0.1%时,柠檬酸具有较好的护色效果。EDTA-2Na或Vc均可提高柠檬酸的护色效果,但添加浓度与雷竹笋产品的储藏环境有关。两种复合配方0.1%柠檬酸-0.1%EDTA-2Na、0.1%柠檬酸-0.05%Vc具有较好的护色效果,可以用于二次杀菌软包装清水雷竹笋储运和销售过程中的护色。

Citric acid,EDTA-2Na,and Vitamin C were used as color-protection agents in soft-packed bamboo shoots for second sterilization. The color of bamboo shoots was measured under high-temperature or light-enhanced stored environments to optimize the color-protection formula. The results show that citric acid could well protect the color of bamboo shoots at the concentration of 0. 1%. EDTA-2Na or Vitamin C could enhance the efficacy of citric acid in color-protection,and the effect was related to their concentration and the stored environment. Optimum formula of 0. 1% citric acid-0. 1% EDTA-2Na and 0...
