| The objective of this work was to validate the spectrophotometric method to detect and quantify nitrite using ham pate as a source. The validated analytical conditions were 540 nm wavelength and the samples reading between 40 to 70 minutes after addition of coloring agents. The tested performance criteria were: linearity, matrix effect, selectivity, detection and quantification limit, accuracy, precision and robustness. As the results have obtained linearity in the studied zone (0.125 to 3 g/mL) and matrix effect was not observed, there was not any interference from ascorbic acid, but interference occurred from sodium eritorbate, in concentrations above 2.5 mg/100g. The detection limit was defined as 12.5 mg of nitrite/kg for pate and the quantification... |
