in burger patties with added fruit extracts or Yilmaz (2004) in
low-fat meatballs added with rye bran. However, Sánchez-Zapata
et al. (2010) or Alesón-Carbonell et al. (2005) indicated that the hardnesswas
not modified by the addition of tiger nut fiber or lemon albedo
in pork and beef burgers, respectively. Cohesiveness and springiness decreased
when PFA was added but no statistically significant differences
(p N 0.05) were found between the treated samples and the control.
These results are in concordance with Viuda-Martos, Ruiz-Navajas,
Fernández-López, and Pérez-Alvarez (2010a) in mortadella (cooked
meat product) added with orange fiber or Choi et al. (2010) in
reduced-fat meat emulsion systems addedwith rice bran fiber. Gumminess
and chewiness were influenced by PFA addition. Both parameters
increased (p b 0.05) when the PFA was added. The results obtained
are in agreement with Luruena-Martinez , Vivar-Quintana, and Revilla
(2004) who studied the effects of olive oil and locust bean/xanthan on
the textural properties of low-fat frankfurters or Choi et al. (2010) in
reduced-fat meat emulsion systems added with rice bran fiber.
In cooked burger (see Table 3) all textural parameters studied were
influenced by PFA addition, except cohesiveness and springiness
