Effects of different packaging films on the structure of A. bisporus during storage at 4 °C for 21 days. (a) Firmness decline in different COL packaging films. (b) Firmness decline in different CMC packaging films. (c) β-1,3-Glucanase activity changed in different COL packaging films. (d) β-1,3-Glucanase activity changed in different CMC packaging films. Vertical bars represent the standard deviations of five replicates. ^a–e Means followed by different superscripts indicate the statistically significant different values among treatments for the same storage time (p < 0.05).
