Vc could be reduced by oxidation during the storage of fruits and vegetables. However, certain chlorides (C12, HOCl, ClO,) could reduce loss of vitamins from food (Fennema 1991). Vc contents of the samples were lower than those of the control during the early days of the storage and higher after the twentieth day (Table). The reason may be that the release of chlorine dioxide gas was relatively rapid during the early days and thereby lead to more oxidation. Some researches showed that the membrane system was damaged because of membrane lipid peroxidation, when the balance between activated oxygen production and elimination was destroyed in plant cells under adverse conditions or during the course of senescence (Chen et al. 2004).
