Antioxidant activity of different white teas: Comparison of hot and cold tea infusions.

Highlights: [•] Antioxidant activity (AA) of different grades of white tea was studied. [•] Cold white tea infusions have higher AA than hot infusions. [•] AA correlates with total phenol, flavonoid and catechin content. [•] African white teas may have potential health benefits comparable to Chinese teas. [•] White tea AA does not correlate with type of cultivar, grade or geographical area. [ABSTRACT FROM AUTHOR]
