Mulberry vinegar through yeast and acetic acid bacteria fermentation.
Values are mean±SD (n=3).
Significant differences were compared with the ‘before fermentation’ at ^*p<0.05, ^**p<0.01 and ^***p<0.001 in the same row by Levene’s t-test.
Positive control in assay (captopril IC₅₀: 49.10±0.27 ng/mL).
