3.2. Physico-chemical properties of pork burger
The color coordinates of raw and cooked pork burgers added with
different concentrations of PFA are shown in Table 2. In raw burger,
lightness (L*) increased when PFA was added. Statistically significant
differences (p b 0.05) were found between the treated samples and
the control. This increase is probably due to the fact that PFA, structurally,
is composed of macromolecules that are rehydrated and remain
