Spatial distribution of dry matter in yellow fleshed cassava roots and its influence on carotenoid retention upon boiling

► Spatial variation of dry matter and carotenoid contents in cassava roots. ► Study conducted on unprecedented levels of carotenoid content in cassava roots. ► Positive association between levels of carotenoids and their retention. ► Dry matter content in fresh samples shown to influence retention. ► Evidence of carotene isomerization and lixiviation into boiling water.
