  • Descrição: Interest in the composition of carotenoid esters of fruits is growing because esterification may affect their bioavailability. Thus, the aim was to provide a detailed identification of carotenoid esters in citrus and mango. Orange cv. ‘Valencia’ and cv. ‘Pera’ presented 9 free carotenoids, 38 monoesters, and 60 diesters. Viola­xanthin and luteo­xanthin derivatives were the major ones, followed by anthera­xanthin, lutein, zea­xanthin, β-crypto­xanthin, and zeino­xanthin esters, many of them reported for the first time in orange pulp. The carotenoid ester composition of tangor cv. ‘Murcott’, reported for the first time, showed 8 free carotenoids, 34 monoesters, and 33 diesters, with β-crypto­xanthin esters as major compounds, followed by viola­xanthin and zea­xanthin esters. In citrus, carotenoids were acylated mainly with capric, lauric, myristic, myristoleic, palmitic, palmitoleic, and oleic acids. In mango, 5 free carotenoids, 2 monoesters, and 19 diesters were identified, from which many viola­xanthin and neo­xanthin esters were reported for the first time.
