Quantification of nitrate and nitrite in fresh sausage

The objective of this study was to quantify the nitrate and the nitrite level of four distinctive lots of pork leg and chicken sausages of seven different producers. The experimental outline was at random with a factorial treatment of 7x4. To the obtained data, a variance analysis was applied in order to reach the medium square of the residue. In order to verify homogeneity of the experiments, the Hartley test was used. It was followed by the joint analysis to compare the two types of sausages. The factorial schema of 7x4x2 was applied to obtain the significant F. The Tukey test was also conducted with a 1% significance level. The results indicated that the samples of chicken fresh sausages showed levels between 7.6 to 312.5 ppm for the sodium nitrate fraction and levels between 1.2 to 221 ppm for the nitrite fraction. For the samples of pork leg fresh sausages, the obtained values were between 8.6 to 363.6 ppm for nitrate and between 0.6 to 162.2 ppm for nitrite. Among the chicken sausage lots, the variation ranged from 7.6 to 312.5 ppm for the nitrate fraction and from 1.2 to 221 ppm for the nitrite. The pork leg sausage samples showed values from 100 to 104,3 ppm for nitrate and from 0.6 to 162.2 for nitrite. 7.1% of the samples were in discordance to the legislation.
