Abstract: The most suitable color intensity and reaction condition ofthe Griess photometric method were discussed.The resuits indicated that the concentration of NaN02 should be in the range of 0~1.0 μg/mL accord with Beer’S law,and the linear regressive equation is A = 0.7335p+0.0017,with the correlation coefficient of R =0.9976,the relative standard deviation of < 1.7%, and the recovery rate of 96% 一103.4%.

Key words: Griess photometric method, nitrite, meat products
