The most commonly used method for measuring carotenoid concentration is high-performance liquid chromatography (HPLC). Nevertheless, easier, quicker, and less costly proxy methods exist. We aimed to determine the diagnostic performance of several proxy methods: the spectrophotometer, iCheck Carot...


Jaramillo Valencia, Angélica M.Londoño, Luis FernandoOrozco, Juan CamiloPatiño, GelverBelalcázar, JohnDavrieux, FabriceTalsma, Elise F.[A comparison study of five different methods to measure carotenoids in biofortified yellow cassava (Manihot esculenta)]A comparison study of five different methods to measure carotenoids in biofortified yellow cassava (Manihot esculenta)

Background Large genome-wide association (GWA) studies of European ancestry individuals have identified multiple genetic variants influencing iron status. Studies on the generalizability of these associations to African ancestry populations have been limited. These studies are important given int...

WayneVerhoef, HansVeenemans, JacobienTalsma, Elise F.Harryvan, JanBoekschoten, Mark V.Feskens, Edith J.Melse-Boonstra, Alida[Associations between common variants in iron-related genes with haematological traits in populations of African ancestry]Associations between common variants in iron-related genes with haematological traits in populations of African ancestry

Past research developed reliable equations to base selections for high β-carotene on near-infrared spectroscopy (NIR) predictions (100 genotypes d−1) rather than with high-performance liquid chromatography (HPLC) (<10 samples d−1). During recent harvest, CIAT made selections based on NIR predicti...

Background Biofortified orange-fleshed sweetpotato (OFSP) varieties are being promoted to reduce vitamin A deficiencies due to their higher beta-carotene content. For OFSP varieties to have impact they need to be accepted and consumed at scale amongst populations suffering from vitamin A deficie...


Hummel, MarijkeTalsma, Elise F.Honing, A. van derGama, Arthur ChibwanaVugt, Daniel van derBrouwer, Inge D.Spillane, Charles[Sensory and cultural acceptability tradeoffs with nutritional content of biofortified orangefleshed sweetpotato varieties among households with children in Malawi]Sensory and cultural acceptability tradeoffs with nutritional content of biofortified orangefleshed sweetpotato varieties among households with children in Malawi

Context: Biofortification of staple crops is a promising strategy for increasing the nutrient density of diets in order to improve human health. The willingness of consumers and producers to accept new crop varieties will determine whether biofortification can be successfully implemented. Objecti...

Introduction of biofortified cassava as school lunch can increase vitamin A intake, but may increase risk of other deficiencies due to poor nutrient profile of cassava. We assessed the potential effect of introducing a yellow cassava-based school lunch combined with additional food-based recommen...

Iron and zinc deficiencies are global health problems, affecting mostly pregnant women and young children. In 2016, biofortified iron and zinc beans were introduced in Colombia. The incorporation of biofortified beans into the national school‐feeding program could facilitate adoption and potentia...

Biofortification of staple crops with provitamin A (PVA) carotenoids is an innovative strategy for controlling vitamin A (VA) deficiency in low-income countries (LIC). Plant breeding programs have been successful in developing biofortified varieties of cassava, maize, and orange-fleshed sweet pot...
