胡萝卜镉安全评价监测数据
收藏资源简介：
为了有效监测市场上销售的胡萝卜中镉的含量，避免重金属超标，根据食品安全法的要求，我单位对泰顺县辖区内销售的胡萝卜开展抽样检测，按照国标GB 5009.15-2014《食品安全国家标准 食品中镉的测定》的方法进行检测，得出样品中镉的含量。检测数据对比GB 2762-2017《食品安全国家标准 食品中污染物限量》，可得出该样品是否符合标准要求，该项数据关乎消费者食品安全，有着不可忽视的重要性。对泰顺县辖区内销售的胡萝卜按照GB 5009.15-2014《食品安全国家标准 食品中镉的测定》进行检测，运用如下公式进行计算：X=（C-C0）×V×n/m/1000，式中：X为试样中待测组分含量，单位为毫克每千克(mg/kg)；C为试样溶液中待测组分的质量浓度,单位为微克每升(μg/L)；C0为空白试样溶液中待测组分的质量浓度,单位为微克每升(μg/L)；V为试样定容体积,单位为毫升(mL);m为称取试样的质量,单位为克(g);n为稀释倍数；1000为换算系数 ，可得检查项目的含量数据。将以上检测数据对比国标GB 2762-2017《食品安全国家标准 食品中污染物限量》要求，在限定值内的为合格，超出限定值的为不合格。
To effectively monitor the cadmium content in commercially sold carrots and prevent excessive heavy metal contamination, our testing institution conducted sampling inspections on carrots sold within the jurisdiction of Taishun County in accordance with the requirements of the Food Safety Law. The cadmium content in the samples was determined using the method specified in the national standard GB 5009.15-2014 National Food Safety Standard: Determination of Cadmium in Foods. By comparing the test data with GB 2762-2017 National Food Safety Standard: Maximum Levels of Contaminants in Foods, we can determine whether the samples meet the standard requirements. This data is closely related to consumer food safety and is of undeniable importance. The carrots sold within the jurisdiction of Taishun County were tested according to GB 5009.15-2014 National Food Safety Standard: Determination of Cadmium in Foods, and the content of the test item was calculated using the following formula: X = (C - C0) × V × n / m / 1000 Where: X: Content of the analyte in the test sample, unit: milligrams per kilogram (mg/kg); C: Mass concentration of the analyte in the test sample solution, unit: micrograms per liter (μg/L); C0: Mass concentration of the analyte in the blank test sample solution, unit: micrograms per liter (μg/L); V: Final constant volume of the test sample solution, unit: milliliters (mL); m: Mass of the weighed test sample, unit: grams (g); n: Dilution factor; 1000: Conversion factor for unit conversion, which is used to obtain the final content data of the test item. By comparing the above test data with the requirements of GB 2762-2017 National Food Safety Standard: Maximum Levels of Contaminants in Foods, samples with cadmium content within the specified limit are qualified, while those exceeding the limit are unqualified.
