“…Some scientific studies on foods have reported changes in chemical composition at different stages of development of fruits, vegetables, and leaves (Bulbovas et al, 2005;Telci et al, 2009;Oliveira et al, 2011;Celi et al, 2011;Leite et al, 2011;Peiretti et al, 2013). However, there are no studies that address the different stages of development of beetroot leaves; therefore, the goal of the present study was to investigate the proximate composition, the mineral and fatty acid contents, and the antioxidant activity of in natura and dehydrated beetroot leaves at different stages of development (60, 80, and 100 days) in order to investigate the use of their leaves as food.…”
