Resumo(s)
Spondias mombin fruit is a seasonal product with limited valorization in Mexico, mainly because of its short shelf life and scarcity of available scientific information. In this study, two drying methods—hot air-drying and freeze-drying—were evaluated for the dehydration of S. mombin pulp. Freeze-dried samples presented a higher content of hydrolysable polyphenols (18.92 ± 5.31 mg GAE/g), whereas no significant differences were detected in condensed polyphenols. The total flavonoid content was significantly greater in the freeze-dried pulp (11.32 ± 1.27 mg CE/g). Antioxidant activity assessed by the ABTS and DPPH assays did not differ between treatments; however, the reducing power of the freeze-dried samples was greater than that of the control samples, as determined by the FRAP assay (14.40 ± 1.07 mg TE/g). HPLC–ESI–MS analysis enabled the identification and quantification of polyphenols, organic acids, and monosaccharides, highlighting the presence of compounds belonging to the methoxycinnamic acid family and ascorbic acid. Overall, these findings provide valuable insights that can serve as a basis for future research on the processing and valorization of S. mombin, contributing to the development of advanced processing strategies to improve the stability, quality, and utilization of underexploited fruits.
