摘　　要：为了解市售果脯蜜饯二氧化硫残留现状,采用比色法检测了北京市场上来自北京、上海、河北、山东、福建、浙江、广东、广西、陕西、新疆十个省市的香蕉、橄榄、无花果、李、枣、胡萝卜、苹果、蜜瓜、乌梅、南瓜、芒果、草莓、柑橘、山楂、杨梅、海棠、青梅、猕猴桃、桃、杏、甘薯、番茄等22类材料加工生产的141个果脯蜜饯样品。结果显示,从141个样品总量上看,市场上果脯蜜饯二氧化硫残留合格率为94.3%,绝大部分产品是安全的;从22类加工材料看,二氧化硫残留超标的样品发生在桃、杏、甘薯及番茄4类制品。因此建议生产厂家在生产中加强桃、杏、甘薯及番茄4类产品二氧化硫的安全监控,市场管理者也应重点加强对这四类果脯蜜饯的监测,确保市场上的食品安全,让消费者吃到放心食品。To understand the status of sulfur dioxide residues in preserved fruits, 22 categories, 141 preserved fruits （ banana, olive, fig, plum, date, carrot, apple, honeydew melon, dark plum, pumpkin, mango, strawberry, mandarin, hawthorn, waxberry, chaenomeles speciosa, green plum, kiwi fruit, peach, apricot, sweet potato, tomato） in Beijing market from 10 provinces （Beijing, Shanghai, Hebei, Shandong, Fujian, Zhejiang, Guangdong, Guangxi, Shanxi, Xinjiang） were determined by colorimetric method. Results showed that 94. 3% of the samples were met the national standard, indicating that most of samples were safe. Sulfur dioxide residues of 4 among 22 classes were beyond the national standard, including peaR, apricot, sweet potato and tomato products. We suggested that manufacturers and market supervision department need more focus on peach, apricot, sweet potato and tomato products to ensure the food safety.
