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). J1–J11=chokeberry juices, P1–P3=chokeberry powders, C=chokeberry capsules, FT=chokeberry fruit tea, DB=chokeberry dried berries. Contents of TPC, TN, TF and TA are expressed as mg per 100 g of dry matter (dm) in powder, capsule, fruit tea and dried berry samples. Contents of TPC, TN, TF and TA in juice samples are expressed as mg per L. TPC, TN and TF are expressed as mg of gallic acid equivalent (GAE), while TA are expressed as mg of cyanidin-3-glucoside equivalents (CGE)
