N2 - Phytoene and phytofluene are major abundant dietary carotenoids largely ignored in the context of agro-food and health. The bioaccessibility of phytoene and phytofluene in tomato, carrot, blood orange (sanguinello cultivar), and apricot juices was analysed following simulated gastro-intestinal digestion with coffee cream as a lipid source, and compared with that of other main carotenoids from these matrices. The bioaccessibility of phytoene and phytofluene, and also total carotenoid bioaccessibility, followed the order: sanguinello > apricot > tomato > carrot. Phytoene was consistently the carotenoid with the highest bioaccessibility, up to 97%, generally followed by phytofluene. The higher bioaccessibility of these carotenoids could mainly be due to their marked difference in chemical structure and matrix distribution. For most juices, cis-isomers presented a higher bioaccessibility than their all-trans counterparts (P < 0.05). The dietary source that provided highest amounts of potentially absorbable phytoene/phytofluene was by far tomato juice (5 mg/250 mL juice).
