Standard error of the least square mean (SE): allicin (0.26); (E/Z)-ajoene (0.05); 2-VDT (0.01); DADS (0.01); DATS (0.02)
BH = blended-heated processing, SH = sliced-heated processing
a−fMeans within the columns at the same temperature with different letters indicate a significant difference (P < 0.05)
i−kMeans within the columns at the same processing time with different letters indicate a significant difference (P < 0.05)
x−yMeans within the rows for the same OSC with different letters indicate a significant difference (P < 0.05)
