Lotus (Nelumbo nucifera) is an extensively cultivated vegetable in eastern Asia, particularly in China. Both
lotus rhizome knot (LRK) and lotus leaf (LL) are waste products of the lotus industry. Extracts from LRK and LL
are proposed as antioxidants for meat. Porcine and bovine ground meat samples were subjected to three
treatments: CONTROL (with no additives), LRK (lotus rhizomes knot extract 3% w/w), and LL (lotus leaf
extract 3% w/w). Raw and cooked samples were stored at 4 °C and the antioxidant activity was determined at
1, 3, 6 and 10 days. Antioxidant activity was significantly increased in all meat samples with the addition of
both LRK and LL, but LRK was more effective against lipid oxidation. The results show the potential for using
LRK and LL extracts in the meat industry to prolong shelf life.
