Figure S1. (a) Concentration of phenolic substances, (b) copper(II) reducing antioxidant capacity (CUPRAC) and (c) 2,2-diphenyl-1-picrylhydrazyl (DPPH●) scavenging capacity values of commercial oenological tannins. The technological purpose of the tannins include fining, structuring and finishing, fermentation of white wines and crushing and maceration. Results are the mean ±standard deviation of two experiments performed on different days for three dilutions in quadruplicate (n = 24).
