Hurrell; Sherry A. Tanumihardjo; ETH Zurich; Mahidol University; University of Wisconsin MadisonVitamin A (VA)-fortified rice is a potential intervention strategy to prevent VA deficiency in at-risk populations. Hotextruded, triple-fortified rice grains with added VA, zinc, and iron were produced by hot extrusion technology and their abilityPublication Open Access Triple-fortified rice containing vitamin A reduced marginal vitamin A deficiency and increased vitamin A liver stores in school-aged Thai children.(2014) Siwaporn Pinkaew; Rita Wegmuller; Emorn Wasantwisut; Pattanee Winichagoon; Hurrell, Richard F.; Tanumihardjo, Sherry A.; Mahidol University.
