摘要
以"镇安"红栗为试材,研究采后不同浓度Na2S2O5水浴处理对板栗贮藏过程中部分生理生化指标的影响。结果表明,Na2S2O5水浴处理对板栗贮藏中的腐烂、呼吸强度、淀粉水解速率、可溶性糖和可溶性蛋白的降解有一定的抑制作用,Na2S2O5浓度越大,抑制效果越明显;由于Na2S2O5处理抑制了淀粉的分解和可溶性糖的消耗,所以在贮藏前期各处理板栗的可溶性糖含量均低于对照,但在贮藏结束时可溶性糖含量高于对照。结果表明,Na2S2O5处理对板栗具有较好的贮藏效应。
The effect of different Na2S2O5 water-curing treatments were used to study on the post-harvest physiologic and biochemical characteristics of Zhen＇an chestnut（Castanea mollissima Blume）. The results indicated that Na2S2O5 water-curing treatments depressed rot, respiration intensity, decompose rate of starch and soluble protein during storage; the higher Na2S205 concentration, the more significantly they were depressed; because Na2S205 treatments depressed the decompose rate of starch and the consumption of the soluble sugar, the soluble sugar content of chestnut with Na2S2O5 treatments was lower than that of control in the early period of storage, but higher in the end. The results indicated that sodium mtabisulfite treatment could make preferable better effect on the storage of chestnut.
