    摘要:

    目的 通过调查问卷和实验室温度实测相结合的方法,研究堂食用一次性热饮杯特定迁移量试验的时间和温度。方法 采用调查问卷的方式了解消费者的消费习惯,得出堂食用一次性热饮杯在使用过程中预计接触食品的时间,以此得出堂食用一次性热饮杯特定迁移量试验所需迁移时间;在模拟消费环境下利用真实食品再现堂食用一次性热饮杯的实际使用情况,并用自动温度记录仪记录试验过程中的杯内壁温度变化,以此得出特定迁移量试验所需迁移温度。结果 根据消费者店内堂食消费行为习惯的调研结果,在绝大部分情况下,堂食用一次性热饮杯实际接触饮品的时间为1 h;对热饮杯在实际使用过程中的内壁温度进行实测,结果表明不同条件下一次性热饮杯在1 h内与食品接触的平均温度介于60 ℃~66 ℃之间。结论 根据问卷调查和温度实测的结果,选择一次性热饮杯的特定迁移试验条件为70 ℃、1 h。本研究结果为相关检测机构和实验室在测试堂食用一次性热饮杯迁移量研究提供参考借鉴。

    Abstract:

    Objective To study test time and temperature of specific migration tests for hot drink cup through a questionnaire and a laboratory real temperature measurement method.Methods The consumption habits of consumers were investigated by means of questionnaires, the estimated time of contact with food during the general actual use of the hot drink cup was obtained, and the migration time required for the specific migration quantity test of the hot drink cup was obtained. Using real food to reproduce the actual use of the hot drink cup in a simulated consumption environment, and using an automatic temperature recorder to record the temperature changes during the test, the migration temperature required for the specific migration test of the hot drink cup was obtained.Results According to the survey results of consumers’ consumption habits in a restaurant, most consumers, in the process of eating in the restaurant, had an actual contact time with a hot drink cup of 1 h. According to the temperature measurement results during the actual use of the hot drink cup, its average temperature in different conditions within 1 h was 60 ℃-66 ℃.Conclusion According to a questionnaire and measured temperatures, it is recommended that a specific migration test condition of 70 ℃ for 1 h is selected. This study on specified migration conditions, including duration and temperature, was conducted through investigation and measurements and can be used as a reference to relevant testing institutions and laboratories when testing dine-in hot drink cups.
