Comoros Union presents a considerable biodiversity of food resources that are neglected or still not valorised, as breadfruit. is study aimed to evaluating nutritional and nutraceutical traits of Artocarpus altilis (Parkinson) Fosberg by characterizing its main bioactive compounds, nutritional traits, and antioxidant properties in order to contribute to the development of traditional and innovative uses of this species as functional food (e.g., infant our). Bioactive compound composition, antioxidant properties, protein and sugar content, lipids, bre, and macro-and microelements were observed in these fruits after a speci c drying process. Breadfruit showed positive nutritional traits. e main identi ed phenolic groups were cinnamic acids (with a maximum of 51.88 ± 2.63 mg/100 g DW for chlorogenic acid) and tannins. e highest value of antioxidant activity was 6.40 ± 1.02 mmol·Fe 2+ / kg DW . is preliminary phytochemical investigation may provide a contribution to the identi cation and quanti cation of lead compounds responsible for traditional nutritional and therapeutic claims.
