Potential Use of Torulaspora delbrueckii As a New Source of Mannoproteins of Oenological Interest

[EN]In this work, three MP extracts obtained from Torulaspora delbrueckii were added to red wine, and the changes in phenolic composition, color, and astringency were evaluated by HPLC–DAD–ESI–MS, tristimulus colorimetry, and sensory analysis, respectively. The MP extracts modified wine phenolic com...
