豆腐干亚硝酸盐安全评价检测数据

食品添加剂一直是消费者比较关心的食品安全问题。含亚硝酸盐食品添加剂按标准使用不会对健康造成危害，但长期食用亚硝酸盐超标的食品会对身体产生不可逆的现象。本数据主要用于监测本公司内部生产及流通领域豆腐干亚硝酸盐残留量情况，通过检测数据，可以判断豆腐干中亚硝酸盐的残留量是否符合国家食品添加剂使用标准，避免因亚硝酸盐的残留量超标导致的食品安全问题，为监管部门提供监管依据，进一步保障消费者的食品安全。1、样品来源：本项目抽检的豆腐干全部来源于本公司内生产、流通环节市场主体销售的豆腐干。2.数据检测：样品经前处理后，根据GB5009.33-2016第二法检测原则，利用恒温水浴锅等仪器进行检测，得出数据。3.数据判定：亚硝酸盐含量的计算，X=(M2 x 1000 x V0)/(M3 x V1 x 1000)。X为试样亚硝酸盐含量，单位为mg/kg；M2为测定用样液中亚硝酸钠的质量，单位为μg；V0为试样处理液总体积，单位为mL；M3为试样质量，单位为g; V1为测定用样液体积，单位mL。豆腐干中亚硝酸盐含量标准要求为≤20mg/kg。4.数据应用：通过抽检数据分析研判，我们可以判断豆腐干中亚硝酸盐含量是否超标，避免因亚硝酸盐过量添加产生的食品安全问题，为监管提供依据。Food additives have long been a prominent food safety concern among consumers. The standard application of nitrite-containing food additives poses no health risks, but long-term consumption of foods with excessive nitrite residues will cause irreversible adverse health effects. This dataset is primarily used to monitor the residual nitrite levels in dried tofu products produced and distributed within our company. By analyzing the test data, we can verify whether the residual nitrite content in dried tofu complies with the national food additive use standards, thus preventing food safety incidents caused by excessive nitrite residues, providing regulatory support for relevant authorities, and further safeguarding consumer food safety. 1. Sample Source: All dried tofu samples collected in this project are sourced from dried tofu products sold by market entities in the production and distribution links within our company. 2. Data Detection: Following the second test method specified in GB 5009.33-2016, the samples are tested using instruments such as a constant-temperature water bath after pre-treatment, and the corresponding test data are obtained. 3. Data Determination: The calculation formula for nitrite content is as follows: X=(M2 × 1000 × V0)/(M3 × V1 × 1000) Where: X = nitrite content of the sample, unit: mg/kg; M2 = mass of sodium nitrite in the test aliquot, unit: μg; V0 = total volume of the sample treatment solution, unit: mL; M3 = mass of the test sample, unit: g; V1 = volume of the test aliquot, unit: mL. The standard limit for nitrite content in dried tofu is ≤20 mg/kg. 4. Data Application: Through analysis and assessment of the sampled data, we can determine whether the nitrite content in dried tofu exceeds the standard limit, avoid food safety issues caused by excessive nitrite addition, and provide a basis for regulatory work.
