Nineteen commercial fruit preparations were analyzed for antioxidant capacity (anti-radical power [ARP] and oxygen radical absorbance capacity [ORAC]). ARP and ORAC values of blends with 13% (w/w) bilberry and black currant extract in low-fat milk or low-fat fermented milk were assessed. Antioxidant capacity in 13% berry/fermented milk blends packed in glass or cardboard cartridges and stored for 3 wk in the dark or under fluorescent light was determined. ARP and ORAC values of most fruit preparations greatly exceeded those of plain milk. Milk blends with berry extract increased ARP values 5-fold to 13-fold and ORAC values by 40% to 100%. Packaging material, illumination, and storage period had no consistent effects on antioxidant capacity.
