Abstract: Polysaccharides and oligosaccharides released into Malvar white wines elaborated through pure, mixed, and sequential cultures with Torulaspora delbrueckii CLI 918 and Saccharomyces cerevisiae CLI 889 native yeasts from D.O. "Vinos de Madrid" were studied. Both fractions from different white wines were separated by high-resolution size-exclusion chromatography. Glycosyl composition and wine polysaccharide linkages were determined by GC-EI-MS chromatography. Molar-mass distributions were determined by SEC-MALLS, and intrinsic viscosity was determined by differential viscometer. Yeast species and type of inoculation have a significant impact on wine carbohydrate composition and structure. Mannose residues from mannoproteins were significantly predominant in those cultures where T. delbrueckii was present in the fermentation process in comparison with when pure cultures of S. cerevisiae were present in the fermenation process. Galactose residues from polysaccharides rich in arabinose and galactose presented greater values in pure cultures of S. cerevisiae, indicating that S. cerevisiae released fewer mannoproteins than T. delbrueckii. Moreover, we reported structural differences between mannoproteins released by T. delbrueckii CLI 918 and those released by S. cerevisiae CLI 889. These findings help to provide important information about the polysaccharides and oligosaccharides released from the cell walls of Malvar grapes and the carbohydrates released from each yeast species.
