摘　　要：本实验以红地球葡萄为试材,检测在不同运输距离、产地批次、年份、温度、SO2气体脉冲处理含量下SO2的残留量,结合居民每日推荐葡萄消费量,对葡萄中SO2进行膳食风险评估。结果显示,SO2的检出率为100%,所有实验组中SO2残留量范围是5.04~39.33 mg/kg,均低于国家食品添加剂的限量标准;随着运输距离的增加,SO2在葡萄中不断积累;国外葡萄中SO2含量较低(6.96~12.46 mg/kg);保鲜剂中SO2的释放速率和葡萄自身品质也对SO2的残留起着重要的作用。风险评估结果表明,各处理组风险商值均小于1,食用风险较低,但应考虑保鲜剂可能会导致葡萄的漂白损伤,降低商品价值。In this study, the residual level of sulfur dioxide in Red Globe grapes was determined as a function of transportation distance, harvest batch, harvest year, storage temperature and SO2 gas concentration. The potential health risk assessment of sulfur dioxide via the consumption of Red Globe grapes was also studied based on the recommended daily consumption of grapes. The results showed that sulfur dioxide was detected in all samples in the range of 5.04–39.33 mg/kg, which was lower than the maximum residue limit specified in the national standard. With the increase in transportation distance, SO2 residue continuously accumulated. The level of SO2 residue in imported grapes ranged from 6.96 to 12.46 mg/kg, lower than that in domestic grapes;the release rate of SO2 from the preservative and grape quality had significant influence on the residue of SO2. The health risk assessment results showed that the risk quotient of SO2 was less than 1 for all groups, indicating low health risk, but it should be considered that the preservative may cause bleaching damage to grapes and reduce commodity value.
