Abstract:

Nitrate and nitrite get into human body mainly through vegetables. Nitrite is a kind of toxic substance that can produce
carcinogenic nitrosamines. The major methods currently available for the detection of nitrate and nitrite in vegetables include
spectroscopy, chromatography and rapid assays. This paper, beginning with a comparative introduction to these methods, reviews
recent advances in detection methods for nitrate and nitrite in vegetables and discusses future prospects.

Key words: nitrate, nitrite, detection
