Effects of fermentation time and concentration of FSR on DPPH radical scavenging activity. Each value represents the mean ± SD (n = 3). Different numbers of asterisks represent different levels of significance from one-way ANOVA: a, compared with FSR-0; b, compared with the previous sample; *P < 0.05; **P < 0.01; ***P < 0.001.
