Antioxidant activities of 70% ethanolic extracts of ten leafy green
vegetables were determined and applied in raw beef patties. The extracts
and BHT (positive control) were separately added to patties at
0.1% and 0.5% (w/w) concentrations and the patties were stored at
4 °C for 12 days. The addition of extracts and BHT resulted in concentration
dependent decreases in TBARS values in the beef patties and
also improved meat color stability. The fatsia extract had more effective
antioxidant than the chamnamul (Kim, Cho, et al., 2013). In another
study, the antioxidant efficacy of 70% ethanol and water
extract of 10 leafy edible plants was evaluated in ground beef patties.
