    摘要:

    在测定蜜饯原料重金属残留的基础上,对其腌制过程中重金属含量动态变化进行监测,分析重金属元素在蜜饯腌制过程中的迁移行为。结果表明,原料中常见重金属元素铅、镉、铬、汞、砷的含量分别为0.151 0,0.024 1,0.110 0,0.000 0,0.013 2 mg/kg;腌制时,残留的重金属元素会向腌制液中迁移,且不同重金属元素的迁移量和迁移行为存在明显差异。腌制结束后,铅、镉、镉、砷的含量分别下降至0.077 30,0.018 30,0.037 90,0.004 81 mg/kg。在蜜饯重金属风险控制和评估时,应充分考虑腌制因素带来的不同影响。

    Abstract:

    In this study, based on the determination of heavy metal residues in raw materials, the migration behavior of heavy metal in candied fruits was preliminary analyzed by monitoring dynamic changes of heavy metal content during pickling. The results showed that the contents of Plumbum, Cadmium, Chromium, Mercury and Arsenic in raw materials were 0.151 0, 0.024 1, 0.110 0, 0.000 0, 0.013 2 mg/kg, respectively; During the pickling process, residual heavy metal elements could migrate into the pickling solution, and significant differences were found in migration and relative behavior for different heavy metal elements. The contents of Plumbum, Cadmium, Cadmium and Arsenic were respectively decreased to 0.077 30, 0.018 30, 0.037 90 and 0.004 81 mg/kg, at the end of the pickling. Therefore, in the risk control and assessment of heavy metals in candied fruit, the different effects of curing factors should be fully considered.
