Nutr."],"abstract":"<jats:p>Compound-fermented wines integrate the aromas, flavor compounds, and nutritional components from several raw materials, enriching the flavor and texture of the final product. This study aimed to explore the influence of edible flowers on the quality of pear wine by evaluating the total phenol and flavonoid contents, antioxidant capacities, and tyrosinase inhibition abilities during the mixed fermentation of pears (P) with <jats:italic>Rosa rugosa<\/jats:italic> (PR), <jats:italic>Dendrobium candidum<\/jats:italic> (PD), <jats:italic>Chrysanthemum morifolium<\/jats:italic> (PC), <jats:italic>Lonicera japonica<\/jats:italic> (PL), and <jats:italic>Osmanthus fragrans<\/jats:italic> Lour (PO), using standard methods The findings revealed that total phenol and flavonoid contents, antioxidant capacities, and tyrosinase inhibition abilities significantly increased in compound pear-flower wine. Specifically, total polyphenol content (TPC), total flavonoid content (TFC), the DPPH(1,1-diphenyl-2-picryl-hydrazyl radical) radical scavenging activity (DRSA), Trolox equivalent antioxidant capacity (TEAC), and ferric reducing antioxidant power (FRAP) for PR were 580.69 \u00b1 9.51 mg of gallic acid equivalents (GAE) per liter of the sample (mg GAE\/L), 600.05 \u00b1 36.6 mg of rutin per liter of the sample (mg RE\/L), 0.51 \u00b1 0.00 \u03bcmol of Trolox equivalents (TE) per milliliter (\u03bcmol TE\/mL), 10.11 \u00b1 0.06 \u03bcmol TE\/mL and 6.35 \u00b1 0.35 \u03bcmol of Fe<jats:sup>2+<\/jats:sup> equivalents (FE) per milliliter (\u03bcmol FE\/mL), respectively. Additionally, we further analyzed the volatile and non-volatile components of P and PR at different fermentation stages. A significant difference was observed between the non-volatile and volatile metabolites, with pear rose wine (PRW) demonstrating superior characteristics compared with pear wine (PW). Phenolic acids and flavonoids were closely associated with the formation of non-volatile metabolites, while esters, hydrocarbons, alcohols, and ketones were significantly linked to volatile formation. Notably, 2(5H)-furanone, 5-ethyl-3-hydroxy-4-methyl-, emerged as a significant aroma contributor with a relative odor activity value (ROAV) of 236,348.11, giving a sweet, fruity, nutty taste. Compared with PR, decanoic acid ethyl ester increased 634.67-fold in PRW. These findings provide a foundation for further exploration into optimized fermentation protocols, mechanistic studies on flavor and bioactive compound formation, and potential commercial applications in the functional beverage industry.<\/jats:p>","DOI":"10.3389\/fnut.2025.1604754","type":"journal-article","created":{"date-parts":[[2025,7,21]],"date-time":"2025-07-21T04:10:24Z","timestamp":1753071024000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Influence
