蜜饯中铝残留量的检测及结果分析

Investigation and Analysis of Residual Aluminum in Preserved Fruits

对广东省、福建省、湖南省、浙江省4省的蜜饯产品进行随机抽样,并测量其铝的残留量。626份蜜饯样品中铝残留量的含量范围为0~662.00 mg/kg,铝残留量的平均值为27.22 mg/kg,中位数为11.25 mg/kg,超过40 mg/kg的样品占12.0%。多独立样本Kruskal-Wallis检验(Kruskal-Wallis H)显示,4省蜜饯中铝的残留量无显著性差异,而各类蜜饯中铝的残留量不全相同,以话化类中铝的残留量最高,凉果类、果糕类次之,果脯类、糖霜类、糖渍类中铝的残留量最低。生产蜜饯的半成品盐坯(果坯)有可能是造成蜜饯中铝残留量高的主要原因,需对此环节加强监管,制定盐坯(果坯)采购验收标准,实现盐坯(果坯)来源可追溯。

A random sample of 626 batches preserved fruits were collected from Guangdong Province, Fujian Province, Hunan Province and Zhejiang Province, and the residues aluminum in samples were measured. Re-sults The levels of residues aluminum in preserved fruits range from 0 to 662.00 mg per kilogram, with a mean of 27.22 mg/kg and the median of 11.25 mg/kg. 12%of 626 preserved fruits＆#39;s residues aluminum were higher than 40 mg/kg. Kruskal-Wallis H-test showed that there were no significant difference on 4 provinces , and the residues aluminum of all kinds of preserved fruits was not all the same. The residues aluminum of the speech classes was the highest. Residues aluminum of the cool fruit classes and the fruitcake classes was slightly lower than that of the speech classes. Residues aluminum of the dry and preserved fruit, the icing classes and the glace classes was the lowest. Conclusion residual aluminum in preserved fruits could be related with salt blank（the fruit blank）, which was semi-finished products in the process of preserved fruits. It was necessary to strengthen the regulation of salt billet（fruit billet）, develop acceptance criteria, realize the salt billet origin traceability.
