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.
