All types of peroxides (unpolar, polar and
protein-bound peroxides) nominally increased with storage time
although the increase in protein-bound peroxides in high oxygen
was not significant (P > 0.05, not shown). Unpolar peroxides were
always significantly higher, if KCS were added on the final day of
chill-storage. However, the increase in PFP was small (max 12%
increase in MAP
