Raw, no roasting; R11, roasting at 150°C for 10 min; R12, roasting at 150°C for 20 min; R21, roasting at 250°C for 10 min; R22, roasting at 250°C for 20 min.
Values represent the mean±SD(n=3). Means with different superscript with the column are significantly different (p<0.05) by Duncan’s multiple range test.
