Abstract

In order to investigate the degradation of nitrite by organic acids during the fermentation of pickles, the organic acids were analyzed by high performance liquid chromatography (HPLC), and 6 different kinds of organic acid for nitrite degradation in vitro were studied. The results showed that the pickles contained oxalic acid, tartaric acid, lactic acid, acetic acid, succinic acid and other organic acids. In 72 hours, all 6 kinds of organic acid could degrade nitrite; the order of ability of nitrite degradation was: oxalic acid > tartaric acid > citric acid > malic acid > lactic acid > succinic acid > acetic acid, and the nitrite degradation rate also increased with the increase of the initial concentration of organic acid. The temperature could also improve the degradation of organic nitrite.
