Comparison with Standard Methods
Seven cured meat products were analyzed by the proposed
methodology, as well as by the official standard method
(AOAC 1995). The analytical results are summarized in
Table 5. Figure 2 presents the electropherograms obtained
for the sample extracts. Identification of the nitrate and
nitrite was achieved using spiking techniques. The results
obtained by CE were consistent with those obtained by the
AOAC method in terms of both precision and accuracy, as
established by F test and t test calculations (all values fell
below the critical values for t of 2.98 and for F of 19.0, at
p=0.05).
