大石葡萄残留嘧菌环胺抽样检测数据
收藏资源简介：
临海市特色农产品“大石葡萄”为国家地理标志证明商标，为更好保证消费者的安全，我单位对其开展抽样检测。检测数据对比国标GB 23200.8-2016 《食品安全国家标准 水果和蔬菜中500种农药及相关化学品残留量的测定 气相色谱-质谱法》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：对抽检样品的各项数据按照如下公式进行计算：X=C×(V1×V3×1000)/(V2×m×1000)，式中：X为试样中测试项目的含量，单位为mg/kg；V1为提取溶剂总体积，单位为mL；V2为吸取出用于检测的提取溶液的体积，单位为mL；V3为样品溶液定容体积，单位为mL；m为取样量，单位为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 23200.8-2016 《食品安全国家标准 水果和蔬菜中500种农药及相关化学品残留量的测定 气相色谱-质谱法》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。
The characteristic agricultural product 'Dashi Grape' from Linhai City holds the national geographical indication certification trademark. To better ensure consumer safety, our unit has conducted sampling inspections on it. By comparing the test data with the data requirements stipulated in National Standard GB 23200.8-2016, the National Food Safety Standard: Determination of 500 Pesticides and Related Chemical Residues in Fruits and Vegetables by Gas Chromatography-Mass Spectrometry (GC-MS), we can determine whether the sample is qualified. This data is critical to consumer food safety and has an indispensable significance. 1. Algorithm Rules: Calculate each test parameter of the sampled products using the following formula: X=C×(V1×V3×1000)/(V2×m×1000). In the formula: X represents the content of the test item in the sample, with the unit of mg/kg; V1 represents the total volume of the extraction solvent, with the unit of mL; V2 represents the volume of the extraction solution withdrawn for detection, with the unit of mL; V3 represents the final volume of the sample solution, with the unit of mL; m represents the sampling mass, with the unit of g; 1000 is the conversion factor. The content data of the inspection item can be obtained via this formula. 2. Data Analysis: Compare the above test data with the data requirements stipulated in National Standard GB 23200.8-2016, the National Food Safety Standard: Determination of 500 Pesticides and Related Chemical Residues in Fruits and Vegetables by Gas Chromatography-Mass Spectrometry (GC-MS). Samples with results within the specified limits are qualified, while those exceeding the limits are unqualified.
