The values are presented as mean±standard deviation (S.D.). The same letter in the superscript in the same column indicates no significant differences (p>0.05). TAC is expressed as mmol of Trolox equivalent (TE), while RP is expressed as mmol of Fe2+ equivalents (FE). For chokeberry juices TAC and RP are expressed as mmol of TE per L and mmol of FE per L, respectively. For powder, capsule, fruit tea and dried berry samples TAC and RP are expressed as mmol of TE per 100 g of dry matter (dm) and mmol of FE per 100 g of dm, respectively J1–J11=chokeberry juices, P1–P3=chokeberry powders, C=chokeberry capsules, FT=chokeberry fruit tea, DB=chokeberry dried berries
