The combined use of selected Saccharomyces cerevisiae and non-Saccharomyces strains is becoming an effective way to achieve wine products with distinctive aromas. The purpose of this study was to further improve the wine aroma complexity through optimizing inoculation protocols of multi-starters. The three indigenous non-Saccharomyces strains (Torulaspora delbrueckii, Hanseniaspora vineae, and Lachancea thermotolerans) and their pairwise combinations (co-inoculation) were sequentially inoculated with S. cerevisiae in Petit Manseng grape must, resp. Results evidenced a higher divergence in aroma compounds produced by two different non-Saccharomyces species compared to single species. Especially for the combination of T. delbrueckii and L. thermotolerans, the concentrations of most Et esters were further increased, contributing to a higher score of pineapple note in agreement with sensory anal. Our results highlighted that the inoculation of more than one non-Saccharomyces species is a potential strategy to improve the aroma diversity and quality of industrial wines. This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0Recommanded Product: Isopentyl hexanoate).
Isopentyl hexanoate (cas: 2198-61-0) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: Isopentyl hexanoate
