Title

Quality of selected white tea types

Abstract

The objective of this study was to assess the quality of white tea types less popular on the Polish market including the evaluation of sensory quality of tea infusions and the antioxidant capacity towards the ABTS•+ radicals. The following contents were determined: water, protein, mineral compounds in the form of ash, fat, tannins, and vitamin C, as was the presence of adulterants in the teas. It was proved that the white teas analyzed were characterized by the high quality and desirable sensory properties, as well as by the high antioxidant capacity that varied in the range of 0.50 to 3.23 mM TE/g. In the tea infusions, a delicate jasmine aroma and taste prevailed. No unwanted, highly intense tastes such as paper-like or bland taste were reported in the studied te infusions. The teas analyzed were characterized by a similar chemical composition, except for the content of protein, fat and water.
