All these values
determined in our present research were higher than those reported
by Sárraga, Carreras, and Regueiro (2002) in dry-cured Longissimus
dorsi. This could be mainly due to the differences in meat
species and process conditions. Furthermore, the addition of KNO3
into muscle samples during salting might also be an important
cause for the lower decrease in GSH-Px activity in the research of
Sárraga et al. (2002). Because, in addition to give characteristic colour
and flavour of cure meat, nitrate/nitrite also play a role as antioxidant
and antimicrobial agent
