Biofortified sorghum lines are being developed to target vitamin A deficient populations in Sub-Saharan African. The purpose of this study was to screen diverse samples of transgenic sorghum for the content and delivery of provitamin A carotenoids using an in vitro digestion model. The germplasm background and transgenic sorghum contained 1.0–1.5 and 3.3–14.0 μg/g β-carotene equivalents on a dry weight basis (DW), respectively. Test porridges made from milled sorghum contained 16–250 μg/100g β-carotene equivalents on a fresh weight basis. Micellarization efficiency of all-E-β-carotene was lower (p
