摘要
将巨峰、玫瑰香以及红地球葡萄,分别包装在聚乙烯微孔保鲜袋内,置于(20±1)℃温度条件下,用臭氧消毒机每天分别向袋内通气0.5min(臭氧浓度150mg/m3)和1min(臭氧浓度300mg/m3),进行模拟货架期臭氧处理对品质影响的试验。试验结果表明,2种浓度的臭氧处理显著地减轻了巨峰葡萄果梗霉变、果实腐烂率及失重率;显著地降低了红地球葡萄腐烂率及果实失重率,而对可溶性固形物和可滴定酸含量的影响较小;对降低玫瑰香葡萄腐烂率有一定作用,而对其它指标的影响不明显。
Kyoho, Muscate Hamburg and Red Globe were packed in film bag and treated with different concentration ozone at （20±1） ℃, and separately ventilated 0.5 min （ozone concentration 150 mg/m^3） and lmin （ozone density 300 mg/m^3） to the bag with the ozone sterilizing machine every day, to simulate shelf life of ozone treatment on the quality of grapes. The results showed that, two ozone concentration treatment obviously inhibited the fungal growth on stalk, berry decay and weigh loss rate of Kyoho grape. The treatment with ozone 1 min every day clearly reduced the berry decay and weigh loss rate of Red Globe grape, and had no evident effects on the contents of soluble solid and titratable acid. Treatment with ozone 1 rain every day evidently reduced the berry decay rate of Muscate Hamburg grape, the effects of treatment on the other index was not evident.
