食品中脱氢乙酸及其钠盐含量检测数据

基于规范的食品抽（取）样和实验室检测，并按照标准方法处理原始检测数据，得到食品样本中脱氢乙酸及其钠盐（以脱氢乙酸计）含量数据，依据食品安全国家标准对样品进行合格性评价，判定食品中脱氢乙酸含量是否达标。该数据可为食品生产主体在食品生产过程中规范食品添加剂使用行为，以及监管部门开展食品安全监管提供科学依据。1.样品检测：依据相关规范组织抽样及制样，精确称取2.5000g均质食品试样，按照《食品安全国家标准 食品中脱氢乙酸的测定》（GB 5009.121-2016 第二法 液相色谱法）进行前处理及上机检测，读取样品浓度C（μg/mL）数据。2.数据处理：根据计算式计算样品中脱氢乙酸含量检测结果X（g/kg）=（C×V×n）/（m×1000），其中，C（μg/mL）为样品浓度，V（mL）为定容体积，n为稀释倍数，m（g）为取样量。3.合格率计算：依据《食品安全国家标准 食品添加剂使用标准》（GB 2760-2014）对样品进行合格性评价，并计算合格率（%） = (合格样品数量 / 检测样品数量) ×100%。4.数据应用：食品生产主体可根据食品中脱氢乙酸含量检测数据，对照食品安全国家标准，规范生产过程中食品添加剂使用行为，确保出厂产品合格；食品监管部门根据检测数据及合格率统计数据精准开展食品安全监管和风险交流。

Based on standardized food sampling and laboratory testing, and processing the original test data via standard methods, the content data of dehydroacetic acid and its sodium salts (calculated as dehydroacetic acid) in food samples are obtained. The qualification of samples is evaluated according to national food safety standards to determine whether the dehydroacetic acid content in foods meets the requirements. This dataset can provide scientific basis for food production entities to regulate the use of food additives during food production, and for regulatory authorities to carry out food safety supervision.

1. Sample Testing: Organize sampling and sample preparation in accordance with relevant specifications. Accurately weigh 2.5000 g of homogenized food sample, conduct pretreatment and instrumental analysis in accordance with "National Food Safety Standard - Determination of Dehydroacetic Acid in Foods" (GB 5009.121-2016, Method 2, Liquid Chromatography), and record the sample concentration C (μg/mL).

2. Data Processing: Calculate the detection result X (g/kg) of dehydroacetic acid content in the sample using the formula: X = (C × V × n) / (m × 1000), where C (μg/mL) is the sample concentration, V (mL) is the constant volume, n is the dilution multiple, and m (g) is the sample weight.

3. Qualification Rate Calculation: Conduct qualification assessment on samples in accordance with "National Food Safety Standard - Use of Food Additives" (GB 2760-2014), and calculate the qualification rate (%) = (number of qualified samples / number of tested samples) × 100%.

4. Data Application: Food production entities can use the dehydroacetic acid content test data of foods, compare with national food safety standards, regulate the use of food additives in the production process, and ensure that products leaving the factory are qualified; food regulatory authorities can carry out precise food safety supervision and risk communication based on the test data and qualification rate statistics.
