In Brazil, street markets and vegetable distributors discard vegetable leaves and stems, including those of carrot (Dacus carota L.). Seeking to reduce the waste of vegetable parts, this study characterized chemically the leaves of organically grown carrot in three stages of development to determine the best time for their removal and consumption as food. The leaves were dehydrated in an oven at 70 °C for 43 hours and analyzed for chemical composition, antioxidant activity, chlorophyll content, fatty acid composition, and also calcium (Ca), sodium (Na), potassium (K), magnesium (Mg), manganese (Mn), iron (Fe), zinc (Zn), and copper (Cu) contents. The analyses indicated 100 days of development as the ideal stage for the removal and consumption of carrot...

Provitamin a activity of Brazilian carrots: leaves and roots, raw and cooked and their chemical composition Ciênc. Tecnol. Aliment.
Almeida-Muradian,Ligia Bicudo; Popp,Veronica; Farias,Marcela Paiva.
The purpose of this study was to determine through carotenoid analysis, the provitamin A value of two carrots (Daucus carota L.) cultivars (Brasilia and Beta3), leaves and roots, raw and submitted to two ways of cooking: boiling and microwave. Proximate analysis results are also presented for a better characterization of these vegetables (moisture, ash, lipids, proteins, fiber and total carbohydrates). The main carotenoids sources of provitamin A in this vegetable, both in leaves or roots was β-carotene and α-carotene. α-carotene shows half of the provitamin A value of β-carotene. Samples of the Brasilia cultivar presented the better provitamin A value both for leaves and roots. The results for raw samples of the Brasilia cultivar were 464.48 RE/100g for...
