Seven components were obtained in both SSF and LSF processes. The first two components accounted for 89.2% and 99.2% of the total variance for LSF and SSF, respectively. In both fermentation processes, non-flavonoid compounds
(hydroxybenzoic acids and hydroxycinnamic compounds) were positively correlated to antioxidant activity. Previous studies have shown that free and combined hydroxycinnamic compounds exhibit greater antioxidant activity than hydroxybenzoic acids
