H_2O_2溶液消除芹菜中亚硝酸盐的研究

Study on removing nitrite in celery by hydrogen peroxrde

研究了用H2O2溶液浸泡芹菜以消除其中的亚硝酸盐含量。结果表明,被测芹菜经过H2O2溶液浸泡之后,亚硝酸盐的含量明显降低,在303K时,用浓度为0.001 mol/L H2O2溶液浸泡芹菜40 min,效果最好。

The removing nitrite in celery by hydrogen peroxrde is studied. The results indicate that the nitrite content of the celery is reduced distinctly when the celery is soaked by hydrogen peroxide. There is the best effect in the temperature is 303K, the concentration of hydrogen peroxide is 0. 001mol/L, and the soaked time is 40min.
