Non-thermal technologies such as ultraviolet-C (UV-C) irradiation have been explored to delay ripening and improve the quality of fresh produce; however, information on the response of S. purpurea to UV-C treatment remains limited. This study evaluated the effects of different UV-C doses (0, 1, 2, 3, 4, and 5 kJ\u00b7m\u22122) on the postharvest quality and antioxidant properties of seriguela fruits stored at ambient temperature for eight days. Physical, physicochemical, and functional parameters were analyzed, including mass loss, firmness, color attributes (L*, chroma, and hue angle), soluble solids, pH, titratable acidity, vitamin C, total phenolics, and antioxidant activity (DPPH and ABTS). UV-C treatment significantly affected most quality attributes during storage. Intermediate doses (1\u20134 kJ\u00b7m\u22122) reduced mass loss, delayed softening, and improved color stability compared with untreated fruits. In addition, UV-C irradiation promoted the accumulation of bioactive compounds, with higher vitamin C levels at 1 kJ\u00b7m\u22122 and increased phenolic content and antioxidant activity at 2\u20134 kJ\u00b7m\u22122. Multivariate analysis confirmed that intermediate UV-C doses were associated with better preservation of overall fruit quality.<\/jats:p>","DOI":"10.3390\/foods15091604","type":"journal-article","created":{"date-parts":[[2026,5,6]],"date-time":"2026-05-06T09:30:22Z","timestamp":1778059822000},"page":"1604","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Effects of UV-C Irradiation on Postharvest Quality, Bioactive Compounds, and Antioxidant Activity of Seriguela Fruit (Spondias purpurea L.)
