鸭舌中亚硝酸盐快检数据
收藏资源简介：
对平阳县农贸市场流通领域中鸭舌开展快检，对鸭舌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鸭舌，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，对鸭舌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；具体市场样品不合格率（如：AC市场样品不合格率）=具体市场样品不合格数/具体市场样品总数。通过对全部样品不合格率的分析，了解鸭舌中亚硝酸盐现状，通过对不同市场样品的不合格率的分析，了解哪些市场样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 study targeting duck tongues in the circulation links of agricultural product markets in Pingyang County was carried out, with nitrite testing conducted on the samples, to provide factual evidence for qualification rate evaluation, and offer technical support and reference for government supervision and consumer purchasing decisions. 1. Data Collection: Duck tongue samples were randomly collected from agricultural product markets across the entire county for nitrite content analysis and investigation. 2. Data Testing: The national standard GB 5009.33-2016 National Food Safety Standard - Determination of Nitrite and Nitrate in Foods was adopted to perform nitrite testing on the duck tongue samples, obtaining relevant test data. 3. Data Processing: The nitrite-related test results were screened out to evaluate the unqualified rate. The overall unqualified rate of all samples = total number of unqualified samples / total number of collected samples; The unqualified rate of samples from a specific market (e.g., unqualified rate of samples from Market AC) = number of unqualified samples from the specific market / total number of samples from that market. Through analysis of the overall unqualified rate of all samples, the current status of nitrite in duck tongues can be understood; by analyzing the unqualified rates of samples from different markets, markets with relatively high unqualified rates can be identified, providing data references for consumers' healthy diet, and offering guidance for determining key detection targets in subsequent work.
