【摘要】 以巨峰葡萄（Kyoho）为试验材料,分别以蒸馏水、各浓度壳聚糖溶液（0.5%、1.0%、1.5%）、二氧化硫（SO₂）保鲜剂、SO₂保鲜剂与各浓度壳聚糖溶液（0.5%、1.0%、1.5%）共同处理,后置于0℃环境下贮藏,通过对贮藏过程中果实各项生理指标的检测和分析,研究了壳聚糖降低SO₂对葡萄的伤害程度。结果表明:壳聚糖处理能够减少SO₂对失重率、落粒率、硬度等方面所带来的伤害。故壳聚糖对于巨峰葡萄的采后贮藏品质有着较好的控制,是一种具有广阔市场前景的葡萄保鲜剂。更多还原

【Abstract】 Kyoho table grapes was used as the experimental material,and treated with distilled water,each concentration of chitosan solution（0.5%,1.0%,1.5%）,sulfur dioxide（SO₂）preservative,and SO₂preservatives were treated with each concentration of chitosan solution（0.5%,1.0%,1.5%）,then stored at0℃.Through the detection and analysis of the physiological indexes of fruits during storage,chitosan was selected to reduce the damage of SO₂to grape.The results showed that:chitosan treatment could reduce the damage caused by SO₂on the rate of weight losing rate,dropping rate,hardness and so on.Therefore,chitosan has a good control on the postharvest storage quality of Kyoho table grape,and it is a grape preservative with broad market prospects.更多还原
