This work evaluates the ability of albedo (AGP) and flavedo (FGP) grapefruit powders (2 and 5%) to improve the quality of raw pork patties during chilled storage (2 °C/9 days/under darkness). First, AGP and FGP were analysed for their in vitro antioxidant activity (AOX) (total phenolic content, TPC; antiradical DPPH• activity; reducing power ability, RP). Then, pork patties treated with AGP and FGP (0, 2 and 5%) were evaluated for pH, lipid oxidation (thiobarbituric acid reactive substances, TBARS), metmyoglobin formation (MetMb), colour (a*) and water holding capacity (WHC) during chilled storage (2-4 °C/9 days/without illumination). The results indicate that AGP and FGP were an important source of phenolic compounds and exerted good antiradical DPPH• and RP properties (P<0.05). No significant differences were found in pH or WHC of pork patties treated with grapefruit powder (P>0.05). Also, the pork patties treated with AGP and FGP at 2% showed the lowest TBARS and MetMb values in comparison to the control group (P<0.05). These results indicate that albedo and flavedo grapefruit powders have great potential for preventing oxidation in pork patties and could be used as a natural ingredient for preserving the shelf life of meat and meat products during refrigerated storage.
