3.2. Oxidative stability of cooked burger patties
Lipid and protein oxidation products were quantified in cooked
burger patties (Table 4). The amount of malonaldehyde (MDA) and
other lipid-derived carbonyls were assessed by using the TBA method.
The amount of TBA-RS was significantly higher in control patties than
in the treated counterparts. Amongst patties manufactured with
vegetable oils, A-burger patties displayed significantly smaller TBA-RS
numbers than S- and O-burger patties. The effect of using vegetable
oils as ingredients in meat products has been profusely studied in
terms of the fatty acid composition whereas the impact on lipid
