The study evaluated the bioactive components and antioxidant properties of sugarcane phenolic extracts (SCPE) against lipid oxidation in raw ground pork and beef during refrigerated storage conditions. Results showed that SCPE has a high total phenolic content of 35.9 g GAE/100 g sample majority of which are vanillic (799.77 mg/100 g), sinapic (434.38 mg/100 g), and coumaric (342.37 mg/100 g) acids. These phenolic compounds exhibited strong radical scavenging activities against DPPH (191.00 mg TE/g) and ABTS (359.80 mg TE/g) radical, ferric reducing capacity (97.80 mg TE/g), and lipid peroxidation inhibition (120.20 mg TE/g) activities which are comparable to BHT. Supplementation of SCPE at 400 mg/kg fresh weight of ground pork and ground beef improved the antioxidant activities of meat samples, leading to the delay in TBARS formation, lower reduction in heme iron content, and minimal increase in metmyoglobin content during 14-day refrigerated storage as compared to BHT-treated and control. Moreover, the redness of meat was preserved in SCPE- and BHT-treated samples as measured by a* color value. Correlation heat maps showed that TBARS, metmyoglobin, and ΔE are positively correlated with each other, and at the same time showed negatively correlated with heme iron and a*. This study revealed that antioxidant extracts from sugarcane presented a positive effect on the oxidative stability of raw ground pork and beef during refrigerated storage. |
