This study evaluated the influence of ripening stage (unripe, ripe, and overripe) on the chemical composition, color attributes, antioxidant capacity, and microstructural evolution of Hass avocado peel. Significant differences (p &lt; 0.05) were observed in proximate composition and color coordinates among ripening stages. Overripe peel exhibited the highest concentration of total phenolic compounds (168.02 \u00b1 3.28 mg GAE\/g) and antioxidant capacity, determined by ABTS\u2022+ (410.25 \u00b1 1.01 \u00b5M TE\/g) and FRAP (782.84 \u00b1 2.62 \u00b5M TE\/g). Environmental scanning electron microscopy (ESEM) and confocal laser scanning microscopy (CLSM) revealed progressive degradation of cuticular layers and chlorophyll-containing cells during ripening. Surface fractal dimension texture (FDT) significantly decreased from 1.54 \u00b1 0.02 in unripe peel to 1.47 \u00b1 0.01 in overripe peel, indicating a reduction in surface structural complexity. Principal component analysis (PCA) explained 99.0% of the total variance and revealed a clear association between FDT, chlorophyll fluorescence (\u03bbex = 450 nm), and color parameters, while total phenolic content and antioxidant capacity were associated with advanced ripening stages. These findings demonstrate that FDT is a promising indicator of peel senescence and suggest that structural disassembly during ripening is closely associated with enhanced phenolic extractability and antioxidant potential. This work provides a comprehensive framework for monitoring postharvest quality and supports the valorization of avocado peel as a source of bioactive compounds for food applications.<\/jats:p>","DOI":"10.3390\/molecules31183280","type":"journal-article","created":{"date-parts":[[2026,9,16]],"date-time":"2026-09-16T09:06:37Z","timestamp":1789549597000},"page":"3280","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Changes in Phenolic Compounds, Antioxidant Capacity, Color, and Microstructure of Hass Avocado (Persea americana) Peel During Ripening"],"prefix":"10.3390","volume":"31","author":[{"given":"Madeleine","family":"Perucini-Avenda\u00f1o","sequence":"first","affiliation":[{"name":"Programa de Investigaci\u00f3n y Posgrado en Ciencia de los Alimentos, Facultad de Qu\u00edmica, Universidad Aut\u00f3noma de Quer\u00e9taro, Cerro de las Campanas S\/N, Col.
