腌制蔬菜中亚硝酸盐快检数据

对平阳县农贸市场流通领域中腌制蔬菜开展快检，对腌制蔬菜开展亚硝酸盐项目检测，从而为合格率评价提供事实依据，为政府监管、消费者购买提供参考和技术支撑。1.数据采集：在全县范围内的农贸市场随机抽取腌制蔬菜，对其亚硝酸盐展开分析调查。2.数据检测：采用GB 5009.33-2016《食品安全国家标准食品中亚硝酸盐与硝酸盐的测定》国家标准，对腌制蔬菜开展亚硝酸盐项目检测获得相关数据。3.数据处理：筛选出亚硝酸盐问题项检测结果，进行不合格率的评估。全部样品不合格率=全部样品不合格数/全部样品总数；具体类别样品不合格率（如：腌包菜不合格率）=具体类别样品不合格数/具体类别样品总数。通过对全部样品不合格率的分析，了解腌制蔬菜中亚硝酸盐现状，通过对不同样品的不合格率的分析，了解哪些商品的不合格率比较高，为消费者的健康饮食提供数据参考，也为后续工作中确定需要重点检测对象提供指导。

A rapid detection campaign targeting pickled vegetables in the circulation sector of farmers' markets in Pingyang County was conducted, with nitrite tests performed on the pickled vegetables. This work provides factual basis for qualification rate evaluation, as well as reference and technical support for government supervision and consumer purchasing decisions.
1. Data Collection: Pickled vegetable samples were randomly selected from farmers' markets across the county to conduct analytical investigations on their nitrite content.
2. Data Detection: Nitrite tests were conducted on the pickled vegetables in accordance with GB 5009.33-2016 National Food Safety Standard for the Determination of Nitrite and Nitrate in Foods, to obtain relevant test data.
3. Data Processing: The test results for nitrite-related non-conforming items were screened out to evaluate the disqualification rate. The disqualification rate of all samples = (number of disqualified samples among all samples) / total number of all samples; The disqualification rate of specific category samples (e.g., disqualification rate of pickled cabbage) = (number of disqualified samples in the specific category) / total number of samples in the specific category.
By analyzing the disqualification rate of all samples, we can gain insights into the current status of nitrite levels in pickled vegetables. By analyzing the disqualification rates of different sample categories, commodities with relatively high disqualification rates can be identified, providing data references for consumers' healthy dietary choices, as well as guidance for determining key detection targets in subsequent work.
