The best process for preparation of test strips for rapid detection of nitritesin food was explored by using the color reaction principle of sulphanilic acid and naphthyl ethylenediamine dihydrochloride. The sulphanilic acid and naphthyl ethylenediamine dihydrochloride were respectively soaked on to the test paper and the test paper was assembled to rapid test strips when dried. Meanwhile,reference colorimetric card was prepared with 100 mg/L,80 mg/L, 60 mg/L,40 mg/L,20 mg/L,10 mg/L,5.0mg/L 2mg/L,1mg/L nitrites as colorimetric control. The method was rapid,simple,sensitive and accurate as compared with spectrophotometry.
