and stronger DPPH• and ABTS•+ scavenging activities, could be extracted with 40% ethanol in water for 2 h. In situ testing confirmed BCE to be a highly effective antioxidant in raw pork patties because it inhibited both lipid and protein oxidation and stabilised
the red colour during refrigerated storage. These data strongly suggest
that frozen BCE has potential as a natural antioxidant source
for meat and meat product quality preservation. Further research is
needed to identify the specific and main phenolic compounds in
frozen BCE that are responsible for the overall antioxidative capability
in muscle foods.
