Effect of pH on Nitrite Reduction of Pickled Chinese Cabbage

The pickled Chinese cabbage is one of the traditional fermented vegetables in China. In this article, the spontaneous and Lactic acid bacteria(LAB) inoculated fermentation methods were compared. The nitrite peak came forth at the middle stage of natural fermentation, but did not appear at the LAB starter fermentation. The pickled Chinese cabbage with natural and inoculated processing was safe, as no nitrite was monitored at the end of the fermentation. The acid milieu was meritorious in eradicating the cumulated nitrite in pickled Chinese cabbage.
