诸暨市玉米乐果含量安全评价检测数据
收藏资源简介:
为保证玉米安全性,需要对玉米中乐果含量进行把控。《食品安全国家标准 食品中农药最大残留限量》(GB 2763—2021)中规定,玉米中乐果不得检出。本数据主要用于监测诸暨市流通领域玉米含量指标的情况,为监管部门提供监管依据。1、.数据采集:数据采集于诸暨市场的抽检样品;2、对我市市场的抽检产品的检测值按照如下公式进行计算:X=C*V*f/m,式中:X为试样中待测组分含量,单位为毫克每升(mg/L);C为试样待测液中乐果含量,单位为毫克每升(mg/L);V为试样待测液定容体积 ,单位为毫升(mL);m为试样质量 ,单位为克(g) 。可得检查项目乐果的含量数据。3.将以上检测数据对比国标GB 23200.113-2021 《食品安全国家标准 植物源性食品中208种农药及其代谢物残留量的测定》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 ensure the food safety of corn, it is necessary to control the dimethoate content in corn. According to the National Food Safety Standard Maximum Residue Limits for Pesticides in Foods (GB 2763—2021), dimethoate shall not be detected in corn. This dataset is mainly used to monitor the dimethoate content indicators of corn in the circulation sector of Zhuji City, providing a regulatory basis for relevant supervision departments. 1. Data collection: The data was collected from spot-checked corn samples in the markets of Zhuji City. 2. The detected values of the spot-checked products in the local markets are calculated using the following formula: X = C × V × f / m, where: X is the content of the component to be tested in the sample, with the unit of milligrams per liter (mg/L); C is the dimethoate content in the test solution of the sample, with the unit of milligrams per liter (mg/L); V is the constant volume of the sample test solution, with the unit of milliliters (mL); m is the mass of the sample, with the unit of grams (g). The content data of the test item dimethoate can be obtained through this calculation. 3. The above detection data will be compared with the data requirements specified in the National Food Safety Standard Determination of 208 Pesticides and Their Metabolite Residues in Plant-Derived Foods (GB 23200.113-2021). Samples with test results within the specified limit are qualified, while those exceeding the limit are unqualified.
