部分违规生产企业在水产品前期加工环节，将其分割冷冻后放入塑料袋内，并充装一氧化碳，当一氧化碳与肌红蛋白结合后，可使肉色呈现鲜艳的粉红色，看起来与新鲜鱼一样，即使已腐败变质，颜色也可和新鲜的差不多，提高产品的外观卖相，因此一氧化碳可作为水产品的发色剂。
本标准规定了水产品中一氧化碳（CO）残留量检验的抽样、制样和气相色谱测定方法。
本标准适用于金枪鱼、罗非鱼、三文鱼中一氧化碳（CO）残留量的检验。
浩瀚色谱，研制的《甲烷转化炉色谱测水产品中一氧化碳残留量》建立了顶空-气相色谱法测定水产品中一氧化碳的分析方法结果显示,在0.4～5.6μL/mL范围内,一氧化碳浓度和色谱峰面积呈良好的线性关系,相关系数为0.999 8,方法检出限为7μg/kg(S/N=3),定量限为40μg/kg(S/N=10)。平均回收率为88.9%～102.6%,相对标准偏差(RSD)为0.39%～2.89%(n=6)。所建立的分析方法快速、简便,适合水产品中一氧化碳的检测分析。

Some illegal production enterprises divide and freeze aquatic products in the early processing stage, put them in plastic bags, and fill them with carbon monoxide. When carbon monoxide combines with myoglobin, it can make the meat appear bright pink and look like fresh fish. Even if it has spoiled, the color can still be similar to fresh, improving the appearance and appearance of the product. Therefore, carbon monoxide can be used as a coloring agent for aquatic products.
This standard specifies the sampling, sample preparation, and gas chromatography methods for the detection of residual carbon monoxide (CO) in aquatic products.
This standard is applicable to the detection of carbon monoxide (CO) residues in tuna, tilapia, and salmon.
Haohan Chromatography has developed a method for determining residual carbon monoxide in aquatic products using headspace gas chromatography. The results show that there is a good linear relationship between carbon monoxide concentration and chromatographic peak area in the range of 0.4-5.6 μ L/mL, with a correlation coefficient of 0.9998. The detection limit of the method is 7 μ g/kg (S/N=3), and the quantification limit is 40 μ g/kg (S/N=10). The average recovery rate is 88.9% to 102.6%, and the relative standard deviation (RSD) is 0.39% to 2.89% (n=6). The established analytical method is fast, simple, and suitable for the detection and analysis of carbon monoxide in aquatic products.
