油条铝的残留量安全评价检测数据

食品添加剂一直是消费者关心的问题，本数据主要用于监测天台县餐饮主体生产的油条铝的残留量指标的情况，通过检测数据，可以判断油条中铝的残留量是否符合食品安全生产标准，避免因油铝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：本项目抽检的油条来源于天台县餐饮主体自制的油条。 2.数据检测：油条样品经处理后，由YQ519 ICP-MS仪器进行测定，以铝元素特定质量数定性，采用外标法，以铝元素质谱信号与内标元素质谱信号的强度比与铝元素的浓度成正比进行定量分析。 3.数据判定：铝含量的计算，X=(C1-C0)×v×f/m。X为试样铝含量，单位为mg/kg；C1为试样溶液中被测元素质量浓度，单位为mg/L；C0为试样空白液中被测元素质量浓度，单位为mg/L；V为试样消化液定容体积，单位为ml；f试样稀释倍数；m为试样称取质量，单位为g。油条中中铝限量标准是≤100 mg/kg，超过100mg/kg则判定该批次不合格。 4.数据应用：通过抽检数据分析研判，我们可以判断油条中的铝残留是否符合安全标准，防止因油条铝的残留量超标导致的食品安全问题。

Food additives have long been a concern among consumers. This dataset is primarily used to monitor the aluminum residue levels in youtiao (crispy fried dough sticks) produced by food and beverage establishments in Tiantai County. Based on the test data, we can verify whether the aluminum residue in youtiao complies with food safety production standards, prevent food safety incidents caused by excessive aluminum residue, provide regulatory support for relevant authorities, and further protect consumers' food safety.

1. Sample Source: The youtiao samples obtained through sampling inspection in this project are self-made by food and beverage establishments in Tiantai County.

2. Data Detection: After pretreatment, the youtiao samples are tested using a YQ519 ICP-MS instrument. Qualitative analysis is performed based on the specific mass number of aluminum, while quantitative analysis is conducted via the external standard method, where the intensity ratio between the mass spectrometric signals of aluminum and internal standard elements is proportional to the concentration of aluminum.

3. Data Judgment: The aluminum content is calculated using the formula: X=(C1-C0)×v×f/m. Herein, X represents the aluminum content of the sample, with the unit of mg/kg; C1 is the mass concentration of the detected element in the sample solution, unit: mg/L; C0 is the mass concentration of the detected element in the sample blank solution, unit: mg/L; V is the constant volume of the digested sample solution, unit: ml; f is the dilution factor of the sample; m is the mass of the weighed sample, unit: g. The limit standard for aluminum in youtiao is ≤100 mg/kg, and any batch with aluminum content exceeding 100 mg/kg is deemed unqualified.

4. Data Application: By analyzing and evaluating the sampling test data, we can determine whether the aluminum residue in youtiao meets the safety standards, and avert food safety issues caused by excessive aluminum residue in youtiao.
