All cooked burgers (control and PFA) showed higher (p b 0.05) TBA values
than raw burgers (Fig. 2), although in this case too, the cooked PFA burgers
showed lower (p b 0.05) TBA values than the control. These results
were in agreement with Sánchez-Zapata et al. (2012) or Sáyago-Ayerdi,
Brenes, and Goñi (2009) who reported an increased in TBA values in
cooked burgers (added with tiger nut milk or grape antioxidant dietary
fiber respectively) with reference to control samples. This means that
PFA retained its antioxidant effect during cooking. Other authors have reported
the antioxidant potential of naturally occurring plant extracts rich
in phenolic compounds when incorporated in cooked meat products
