Chemical characterization of leaves of organically grown carrot Dacus carota L.) in various stages of development for use as food

Evaluation of beetroot (Beta vulgaris L.) leaves during its developmental stages: a chemical composition study

“…Beetroot leaves showed low n-6/n-3 ratio, on average of 0.48 of carrot leaves (Leite et al, 2011) and 0.20 of beetroot leaves. Analyzing the PUFA/SFA ratio, it was verified that the values obtained for all samples were higher than the minimum value recommended, 0.45 (Her Majesty's Stationery Office, 1994).…”

“…The commonly PUFA present in the lipid fraction of leaves are linoleic (LA, 18:2n-6) and alpha-linolenic (LNA, 18:3n-3) acids, which belong to the ω-6 and ω-3 families, respectively. reported by Pereira et al (2003) and Leite et al (2011) for dehydrated carrot (Dacus carota L.) leaves. The carbohydrate content was higher in 60-day leaves and decreased during the developmental stages (from 53.93± 2.57 to 39.88±1.02 g.kg -1 ).…”

“…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.…”

Today, in literature there are studies available on the reuse of cassava (Silva et al, 2012;Carvalho et al, 2002) and carrot leaves (Pereira et al, 2003;Almeida et al, 2009;Boroski et al, 2011;Leite et al, 2011), but studies on beet leaf are unprecedented.…”

“…The fatty acid founds in the beetroot leaves can be compared to those of carrot leaves (Leite et al, 2011) since both have large amounts of LNA; however, beetroot leaves have a 4.7 times higher content of these acids; 100-day dehydrated carrot leaves had 856.55 mg.100g -1 leaves of and dehydrated beetroot leaves had 4,011.02 mg.100g -1 . Beetroot leaves showed low n-6/n-3 ratio, on average of 0.48 of carrot leaves (Leite et al, 2011) and 0.20 of beetroot leaves.…”
