Abstract: The safety of nitrite and nitrate is currently a research hotspot in the field of food safety. Most fermented foods contain nitrites that results from microbial growth and metabolism. Intake of large doses of nitrite can initiate a series of adverse reactions in the body, increasing the risk of cancerogenesis. In this paper, the dietary sources of nitrite and nitrate and their impacts on human health are reviewed in detail along with a summary of studies on nitrite degradation by lactic acid bacteria, with the aim of providing a solution for safe and effective degradation of nitrite.

Key words: nitrite, nitrate, lactic acid bacteria, degradation
