Tucum & atilde;-do-Amazonas (Astrocaryum aculeatum) is a fruit from the Brazilian Amazon with a high potential for processing and bioactive compound extraction. Understanding the chemical composition of different tucum & atilde;-processed crops may help create and improve high-quality and safe food products for industrial and health-related purposes. However, studies addressing how preservation methods affect tucum & atilde;'s bioactive qualities are still lacking. Therefore, this study aimed to compare the bioactive composition and antioxidant capacity of tucum & atilde; pulp subjected to four preservation methods convective drying, freeze-drying, acidified preserve, and jelly preparation, with fresh and blanched pulp as controls. Carotenoid content ranged from 26.62 to 557.90 mu g/g, total phenolic compounds from 10.01 to 48.54 mg/g, and flavonoids from 0.073 to 0.596 mg/g. Antioxidant activity values were 67.29-215.81 (FRAP) and 0.073-0.596 (ABTS method) mu mol of Trolox equivalent/g. Convective drying and freeze-drying preserved carotenoids best, at 101.92% and 77.17% of fresh control levels. Polyphenols were well preserved by freeze-drying and acidified preserve at 137.39% and 80.81% when compared to fresh pulp. Pearson's correlation indicated a strong relationship (r = 0.858-0.931) between total polyphenols, flavonoids, and antioxidant capacity. Preservation methods significantly affected the bioactive compound levels and antioxidant capacity and these results emphasize the potential of tucum & atilde;-do-Amazonas pulp for significant bioactive compound extraction.
