MAP-T (60% CO2/15% O2/25% N2); MAP-1 (MAP plus WPI films containing 4% (v/v) glycerol); MAP-2 (MAP plus WPI films containing 8% (v/v) glycerol); VP-T (vacuum); VP-1 (vacuum plus WPI films containing 4% (v/v) glycerol); VP-2 (vacuum plus WPI films containing 8% (v/v) glycerol)
Data were taken as a mean ± standard deviation (n = 6). Different lower case in the same row indicated significant differences (P < 0.05)
