Mycotoxins, antioxidant capacity, physicochemical and sensory quality of specialty coffees from Cajamarca, Peru. Food Chemistry Advances, 11, 101310. https://doi.org/10.1016/j.focha.2026.1013102772-753Xhttp://hdl.handle.net/20.500.12955/3145Coffee is a globally important crop with significant economic and social relevance, particularly in the Cajamarca region of Peru, which is recognized for the production of high-quality beans. This study aimed to evaluate the occurrence of mycotoxins in three specialty coffee varieties while simultaneously assessing their physical, sensory, and compositional characteristics. A total of 36 parchment coffee samples were randomly collected from two storage facilities located in the provinces of Jaén and San Ignacio. The results revealed the exclusive presence of aflatoxin G₂, with concentrations varying between storage conditions. The Catimor variety exhibited the highest antioxidant activity and total polyphenol content; however, it showed lower physical yield and reduced sensory scores. In contrast, the Bourbon variety displayed a more balanced profile between bean composition and cup quality, producing a beverage with superior physical and sensory attributes and enriched with bioactive compounds associated with potential health benefits. These findings highlight the relevance of varietal selection, post-harvest management, and storage conditions for maintaining coffee quality. Nevertheless, the detection of aflatoxin G₂ indicates persistent food safety concerns, emphasizing the need for stricter monitoring and control measures during harvesting, drying, storage, and handling to mitigate potential health risks.application/pdfenginfo:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nc-nd/4.0/AntioxidantsAntioxidantesCoffeeCaféBean compositionComposición del granoMycotoxinsMicotoxinasPolyphenolsPolifenolesinfo:eu-repo/semantics/articlehttps://purl.org/pe-repo/ocde/ford#4.01.00https://doi.org/10.1016/j.focha.2026.101310Aflatoxins; Aflatoxina; Coffea arabica; Food safety; Inocuidad alimentaria; Postharves control; Control de plagas (postcosecha)
