Farine de la Patate Douce à Chair Orange : caractérisation des caroténoïdes et conservation/Orange Fleshed Sweet potato flour: characterization of carotenoids and conservation

Orange fleshed sweetpotato contains carotenoids that are responsible for its nutritional value and beneficial effects on the health of consumers. By coupling TLC/MS made with CAMAG TLC-MS interface, five molecules of carotenoids such as β-carotene, α-cryptoxanthin, β-cryptoxanthin, lutein, and zeaxanthin and possibly the isomers of β- carotene (α-carotene, ε-carotene, γ-carotene and lycopene) have been identified in extracts of Orange fleshed sweet potato flour. Total carotenoid retention rates are passed from 84.13% under freezer conservation conditions to 27.39% and 26.10% under CMART and CMARS conservation conditions respectively for fourteen weeks. Strongly correlated (R = 0.94) to total carotenoids contents, total antioxidant levels are preserved at 73% (P
