| 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... |
