Tis study aimed to determine the physicochemical properties of the green tea powders produced from 2 diferent Turkish tea [ Camellia sinensis (L.) O.Kuntze] clones (Derepazarı 7 and Fener) grown under diferent shade levels and harvested during 2 consecutive shooting periods. Moisture, ash, crude fber, and total phenolic contents of the green tea powders were determined based on the experimental factors. Products were also evaluated for their water activity, bulk density, particle size, color, extraction yield, and antioxidant activity. Te shooting period, specifc to Turkish tea cultivation, showed remarkable efects on the main quality parameters of the green tea powders. It is noteworthy that the phenolic content and antioxidant activity of the products did not change signifcantly with treatments. Te green tea powder produced from Derepazarı 7 clone, grown under dark shade and harvested in the frst shooting period, was superior among the tested parameters.
