Analysis on the content of nitrite in cooked meat products in Dalian from 2011-2012

目的了解大连市熟肉制品中亚硝酸盐含量。方法按照《大连市食品安全风险监测实施方案》要求,对2011—2012年采集的160份熟肉制品进行亚硝酸盐含量检测。结果亚硝酸盐检出率为59.4%,超标率为6.2%,最大值121.7 mg/kg;10份超标样品为6份酱卤肉制品与4份熏烤肉制品;散装样品检出率为70.5%,定型包装检出率为38.2%,两者检出率差异具有统计学意义(P<0.01)。结论亚硝酸盐在熟肉制品加工中使用较为普遍,在农贸市场上销售的散装熟肉制品中亚硝酸盐含量超标风险较高。
