Abstract: Rapid determinaton mode of nitrate in vegetable was established by using near infrared spectroscopy (NIRS), withsecond derivative and partial least square regression (PLSR), the multi-correlation coefficient is 0.9819 compared with nationalstandard method and the standard error prediction is 0.56%~6.79%. The method is not only simple and rapid, but also suitablefor fast determination in worksite with no requirement of any chemical regent.

Key words: vegetable, near infrared spectroscopy (NIRS), fast detection, nitrate
