采后次氯酸钠水浴处理对板栗气调贮藏品质的影响

以“燕昌”板栗为试材,研究了采后不同浓度次氯酸钠(NaClO)水浴处理对板栗MA包装贮藏品质的影响。试验结果表明,500 mg/L和1000 mg/L NaClO水浴处理的板栗腐烂率低,显著降低了板栗货架期发芽率,并且可以减缓板栗淀粉的水解速率;500 mg/L NaClO水浴处理可以延缓板栗可溶性蛋白质的降解代谢,减少板栗在贮藏期间的乙醇含量。各浓度处理对可溶性糖含量的影响差异不显著。以上结果显示,500 mg/L NaClO水浴处理的板栗贮藏效果最佳。

Effects of post-harvest treatment with sodium hypochlorite solution on the storage quality of chestnut in modified atmosphere cold-storage

The effects of post-harvest treatment with sodium hypochlorite solution at three concentrations(100, 500, 1000 mg/L) on the storage quality of chestnut "Yanchang" in modified atmosphere(MA) storage were investigated. The treatment with sodium hypochlorite solution of 500 mg/L or 1000 mg/L can reduce the rate of rot, especially the rate of sprouting during the shelf-life significantly. Moreover, the rate of starch hydrolyzation slows down simultaneously. The treatment with sodium hypochlorite solution of 500 mg/L is capable of delaying the catabolism of soluble protein at a certain extent and reducing ethanol content during MA storage. However, there is no obvious difference on soluble sugar content among the three concentration treatments. The results demonstrate that sodium hypochlorite solution treatment can increase storage quality, and 500 mg/L is the best concentration of sodium hypochlorite solution for chestnut storage.
