RT, retention time.
The arrows (↓ and ↑) represent a decrease or increase in metabolite levels after fermentation (day 11) compared to before fermentation (day 0).
Symbols (*) indicate significant difference between the before fermentation (day 0) and after fermentation (day 11) group (*p<0.05; **p<0.01; *** p<0.001).
