目的 摸清碘酸钾加入白醋中不同含量的稳定性。 方法 配成含碘 5 0、10 0、2 0 0mg/L的碘醋 ,各按 5 0 0ml装瓶 ,密封室温阴凉处放置备用。第一年每隔两个月 ,第二、三、四年每隔半年测定一次其碘含量。 结果 5 0、10 0、2 0 0mg/L的碘醋一年碘保存率分别为 :96.0 6%、97.76%、95 .2 0 % ;二年碘保存率分别为 :86.0 6%、92 .42 %、92 .85 % ;三年碘保存率分别为 :76.98%、87.5 2 %、90 .95 % ;四年碘保存率分别为 :71.78%、83 .2 6%、89.3 5 % ,感观上均没有变化。 结论 碘醋第一年的稳定性顺序为 :10 0、5 0、2 0 0mg/L ,第二、三、四年的稳定性顺序为 :2 0 0、10 0、5 0mg/L。
Objective To determine the stability of Potassium Iodate of different contents in pale vinegar. Methods Iodate vinegar of 50 mg/L,100 mg/L and 200 mg/L were prepared and were put into 500 ml bottles and tightly stored in dark and cool place.Every 2 months of the first year,the Iodate content was determined.While in second,third and fourth year ,the work was done every half a year. Result In the first year,the Iodate conserving rate was 96.06%,97.76%,95.20% for 50 mg/L,100 mg/L and 200 mg/L respectively.In the second year, the rate was 86.06%,92.42% and 92.85% .In third year the rate was 76.98%,87.52% and 90.95%.In fourth year ,the rate was 71.18%,83.26% and 89.35%.The appearance and sense of the vinegar did not change. Conclusion The stability sequences of the vinegar was 100 mg/L,50 mg/L and 200 mg/L in the first year.In the second,third and fourth year, the the sequence was 200 mg/L,100 mg/L and 50 mg/L.It was proved that the method of adding Potassium Iodate into vinegar was stable and reliable.
