Carotenoids retention in biofortified yellow cassava processed with traditional African methods

Biofortified yellow cassava is being cultivated in countries with high cassava consumption to improve its population’s vitamin A status. The carotenoid retention in biofortified cassava when processed as boiled, fufu, and chikwangue was evaluated in this study. Commercial biofortified varieties Kindisa and Vuvu and the experimental genotypes MVZ2011B/360 and MVZ2012/044 were used. Fresh cassava roots were processed as boiled, fufu, and chikwangue. Provitamin A carotenoids (pVACs) content of fresh and processed cassava was measured by high‐performance liquid chromatography, and total carotenoids was measured by spectrophotometer.
