The aim of this study was to investigate the antioxidant activity of different solvent extracts of
curry and mint leaf and their effect on colour and oxidative stability of raw ground pork meat
stored at 4±1° C. The results indicated that among the two individual leaf categories, the
ethanol extract of curry leaf (EHEC) and the water extract of mint leaf (WEM) showed higher
DPPH and ABTS+ activity. EHEC also exhibited the highest total phenolic contents while
these were the lowest for WEM. WEM showed the highest superoxide anionic scavenging …
The aim of this study was to investigate the antioxidant activity of different solvent extracts of curry and mint leaf and their effect on colour and oxidative stability of raw ground pork meat stored at 4±1°C. The results indicated that among the two individual leaf categories, the ethanol extract of curry leaf (EHEC) and the water extract of mint leaf (WEM) showed higher DPPH and ABTS+ activity. EHEC also exhibited the highest total phenolic contents while these were the lowest for WEM. WEM showed the highest superoxide anionic scavenging activity (%). The pork meat samples treated with EHEC and WEM showed a decrease in the Hunter L- and a-values and a increase in b-value during storage at 4°C. However, the pH and TBARS values were higher in control samples irrespective of storage periods. In conclusion, EHEC and WEM have the potential to be used as natural antioxidants to minimise lipid oxidation of pork products.
