保鲜剂对宣化牛奶葡萄采后呼吸强度及贮藏品质的影响

Effects of Freshness Keeping Agent on Respiratory Intensity and Storage Quality of 'Xuan-Hua' Milk Grapes

研究二氧化硫(SO2)和二氧化氯(ClO2)作保鲜剂对宣化牛奶葡萄采后呼吸作用的影响及保鲜效果。结果表明,在贮藏过程中,宣化牛奶葡萄呼吸为非跃变型,保鲜剂SO2和ClO2处理能明显抑制葡萄的呼吸强度,有效控制葡萄的褐变及腐烂率,延长保鲜期。而ClO2处理更能延缓叶绿素的损失,保持鲜食牛奶葡萄的嫩绿色泽。

The effect of sulfur dioxide and chlorine dioxide freshness keeping agent treatment on Xuan-Hua＇ milk grape storage was studied.The results showed that under the different conditions of storage,the respiratory pattern of Xuan-Hua＇ milk grape was non-climacteric.Freshness keeping agent treatment inhibited obviously the respiration of grapes fruit,effectively controlled brown and decay incidence,extended the shelf life.Chlorine dioxide treatment had better effect on inhibiting the loss of chlorophyll,keeping Xuan-Hua＇ milk grape green.
