摘要
目的:了解广西市售龙眼(荔枝)干、桂圆肉、保鲜龙眼中SO2的残留情况,为市场监管部门加强食品安全监督提供参考。方法:2010年-2012年随机抽取广西市场上的保鲜龙眼、龙眼(荔枝)干、桂圆肉64个样品,按GB/T5009.34-2003《食品中亚硫酸盐的测定》第二法测定SO2残留量。结果:符合国家卫生标准的43份,合格率67%,其合格率从高到低依次为保鲜龙眼(100%)﹥龙眼干(75%)﹥荔枝干(69%)﹥桂圆肉(50%)。结论:广西市售龙眼(荔枝)干、桂圆肉中,超国家卫生标准的达33%,不同程度地存在SO2残留量超标的情况,桂圆肉中最高SO2残留量超国家卫生标准8.6倍。
Objective：To understand the situation of sulphur dioxide in dried longan, dried litchi, dried longan pulp and fresh longan available in Guangxi, and provide reference basis for the market regulators to strengthen food safety supervision. Methods ： Sixty - four samples of dried longan, dried litchi, dried longan pulp and fresh fruits collected in the trading market from 2011 to 2012 were determined according to the second method of distillation method in Determination of Sulphite in Foods by GB/GS009.34 - 2003. Results： There were 43 samples consistent with the state standards and the qualified rate was 67%. The highest was fresh fruits （ 100% ）, followed by dried longan （75%）, dried litchi （69%） and dried longan pulp （50%）. Conclusion： In Guangxi, there are 33% of the dried longan, dried litchi and dried longan pulp excseding the state health standard, performing different levels of SO2 residues, especially in the dried longan pulp, which is 8.6 times of the state health standard.
