H-BE: high blackcurrant extract; M-BE: medium blackcurrant extract; L-BE: low blackcurrant extract; CON: no blackcurrant extract.

¹Total phenolic and anthocyanin content estimated from direct analysis of drinks by Folin-Ciocalteau method and HPLC respectively.

²Tannins added as an ingredient (H-BE 0 mg, M-BE 60 mg, L-BE 90 mg, CON 150 mg per 200-ml drink) to render drinks equivalent in bitter/astringent taste for blinding purposes.

³Estimated from HPLC analysis of raw extract, not direct analysis of the drinks.
