Introduction. Several studies have demonstrated that foodprocessing affects nutrients such as bioactive compounds, protein, starch, fat, fiber,minerals and antioxidant capacity. Our study examined how heat changes the physicochemicalcomposition and antioxidant capacity of peach-palm fruit (Bactrisgasipaes H.B.K.) during flour production. Materials and methods.Five commercial batches of fruit were assessed for total contents of phenolic compoundsand carotenoids, and hydrophilic oxygen radical absorbance capacity (H-ORAC). The fruitwas then cooked and eventually processed into flour. Results and discussion.No significant changes were found for contents of fat, protein, starch and dietary fiberduring flour production. Cooked peach-palm fruit is a source of Mg, Mn, Cu and K, with100 g of fruit containing between 5% and 13.5% of the recommended daily intake. Cookingalso increased carotenoids by 17%, thus helping to compensate for the 28% loss duringdrying. No stage of processing affected polyphenol contents or H-ORAC.Conclusion. Because of its high bioactive compound content, peach-palmflour shows potential for use in the development of functional foods.
