Phytochemicals in Leaves and Roots of Selected Kenyan Orange Fleshed Sweetpotato (OFSP) Varieties

Abstract: This study reports the inherent phytochemicals contents in leaves and roots of nine sweetpotato varieties from Kenya. Results indicated that vitamin C content varied significantly (P<0.05) among the sweetpotato varieties regardless of the plant part, leaves having significantly (P<0.05) higher levels than in the roots. Total flavonoids and phenolic …

Effects of Organic and Mineral Fertilizers on total antioxidant, polyphenolic and carotenoid contents of Orange fleshed sweetpotato tubers

A field study was conducted to determine the effect of organic and mineral-based fertilizers on phytochemical contents in the tubers of an orange fleshed sweetpotato variety (TIB-440060). Treatments were arranged in a split plot design with three replicates. Tubers harvested have been studied for their total antioxidant contents (TAC), total …

On-farm evaluation of the impact of drying and storage on the carotenoid content of orange-fleshed sweet potato (Ipomea batata Lam.)

Drying of orange‐fleshed sweet potato was evaluated under African rural conditions. Three locally built dryers (open‐air sun, tunnel and shade) were tested using Resisto and MGCL01 varieties in Mozambique. Total carotenoid losses were low in all dryers being 9.2% on average. After drying, sweet potato chips were stored in a …
