酱腌菜制品脱氢乙酸抽样检测数据

为了避免食品安全事故发生，根据食品安全法的要求，我单位对临海市各农贸市场开展抽样检测，得出样品中脱氢乙酸的含量。检测数据对比国标GB 5009.121-2016 《食品安全国家标准 食品中脱氢乙酸的测定》 第二法 液相色谱法中标定的数据要求，可得出该样品是否合格。该项数据关乎消费者食品安全，有着不可忽视的重要性。1.算法规则：对我市相关农贸市场的抽检产品的检测数据按照如下公式进行计算：X=c×V×f/(m×1000)，式中：X为试样中脱氢乙酸的含量，单位为克每千克(g/kg)；c为试样溶液中脱氢乙酸的质量浓度，单位为微克每毫升(μg/mL)；V为试样溶液总体积，单位为毫升(mL)；f为过固相萃取柱换算系数（f=0.5）；m为称取试样的质量，单位为克(g)；1000为换算系数 。可得检查项目的含量数据。 2.数据分析：将以上检测数据对比国标GB 5009.121-2016 《食品安全国家标准 食品中脱氢乙酸的测定》 第二法 液相色谱法中标定的数据要求，在限定值内的为合格，超出限定值的为不合格。To prevent food safety accidents, in accordance with the requirements of the Food Safety Law, our unit conducted sampling and testing on various farmers' markets in Linhai City, and obtained the dehydroacetic acid content in the samples. The test data was compared against the calibration requirements specified in Method 2 (Liquid Chromatography) of GB 5009.121-2016 National Food Safety Standard: Determination of Dehydroacetic Acid in Foods, to determine whether the samples are qualified. This data is closely related to consumer food safety and has significant importance that cannot be ignored. 1. Calculation Rules: For the test data of the sampled products from the relevant farmers' markets in our city, calculate using the following formula: X = c × V × f / (m × 1000) Where: X: Dehydroacetic acid content in the test sample, unit: gram per kilogram (g/kg) c: Mass concentration of dehydroacetic acid in the sample solution, unit: microgram per milliliter (μg/mL) V: Total volume of the sample solution, unit: milliliter (mL) f: Conversion factor for solid-phase extraction cartridge (f=0.5) m: Mass of the weighed test sample, unit: gram (g) 1000: Unit conversion coefficient The content data of the inspection items can be obtained through this calculation. 2. Data Analysis: Compare the above test data against the calibration requirements specified in Method 2 (Liquid Chromatography) of GB 5009.121-2016 National Food Safety Standard: Determination of Dehydroacetic Acid in Foods. Samples with dehydroacetic acid content within the specified limit are qualified, while those exceeding the limit are unqualified.
