to the product increases the value of this coordinate over the control but
with no significant difference (p N 0.05). Chroma (C*) and hue (H*), even
though slightly increased with the addition of PFA, were not significantly
(p N 0.05) affected by the PFA content at any concentrations. From the
point of view of color, PFA could be added to pork burger with no significant
modification in this parameter. In cooked burger (see Table 2), lightness
(L*) was significantly (p b 0.05) affected by the PFA content but no
statistically significant differences (p N 0.05) were found between the
samples added with 2.5 and 5% of PFA. Redness (a*), yellowness (b*),
chroma (C*) and hue (H*) were not significantly (p N 0.05) affected by
the PFA content at any concentrations
