BACKGROUND: Citrus wine, a value-added product of citrus deep processing, often exhibits unwanted bitterness caused by naringin and limonin, along with an aroma, which limits consumer acceptance. This study investigated the potential of co-fermenting Saccharomyces cerevisiae with selected lactic acid bacteria (LAB) to reduce bitterness and enhance aromatic quality. RESULTS: Co-fermentation of Lactiplantibacillus plantarum and Saccharomyces cerevisiae increased α-rhamnosidase activity and reduced naringin concentration from 73.87 ± 0.15 to 39.21 ± 1.62 mg L⁻¹ (P < 0.01), limiting limonin accumulation to 15.32 ± 1.01 mg L⁻¹. This was a 50.79% reduction compared with fermentation using S. cerevisiae alone. A total of 150 volatile compounds were identified by headspace solid-phasemicroextraction coupled with gas chromatography-mass spectrometry (HS-SPME-GC-MS) among which the esters, including ethyl caproate, ethyl 9-decenoate and ethyl laurate were enhanced by co-fermentation. The process also increased the odor activity value (OAV) of isoamyl acetate, isoamyl formate, octanoic acid-2-phenylethanol ester, and nonanal, which contribute to fruity and floral aroma characteristics. Sensory evaluation confirmed reduced bitterness and astringency and improved overall flavor acceptance. CONCLUSION: Co-fermentation of S. cerevisiae and L. plantarum improved citrus wine quality by degrading naringin and limonin to reduce bitterness, enriching key esters to improve aroma, achieving overal...
