偏重亚硫酸钠对葡萄保鲜效应研究

以葡萄重3％的偏重亚硫酸钠处理新鲜葡萄1天后，其Sod,Pod,Cat活性增高，膜脂过氧化受抑制，MDA不积累，细胞膜电导率也有一定增加，有机酸，抗坏血酸及糖等营养成分损失减少，表明偏重亚硫酸钠具有一定的保鲜效果。

Effects of Partial-double Sodium Sulphurous on Storage Character of Grape

After treated with three percent of partial-double sodium sulphurous,the superoxide dismlitase,peroxidase and catalase activity of grape increased,the membrane lipid superoxidation was inhibited,MDA content decreased and the membrane permeability increased while there was only a slight reduction in the content of the organic acid,Vc and sugar.The experiment indicates that partial-double sodium sulphurous can prolong the storage time of grape.
