The main goal of the present work was to access the ability of high internal phase emulsions (HIPEs) to encapsulate fl-carotene. The carotenoid loading capacity of the HIPEs was around 20-fold higher when OSAstarch/chitosan complexes were used than when only OSA-starch was used. This impact could be mainly assigned to the capacity of the former HIPEs to trap carotenoid caystals in a stable form. The OSA-starch/chitosan complexes were shown to absorb on the oil droplets interface and form a 3D network in the aqueous phase, which helped to prevent droplet coalescence induced by fl-carotene crystal. The incorporation of fl-carotene within …
