Kong, Cai-Lin published the artcileFine tuning of medium chain fatty acids levels increases fruity ester production during alcoholic fermentation, Formula: C10H20O2, the main research area is fatty acid fruity ester production alc fermentation; Acyl-CoA: alcohol O-acyltransferases; Alcohol O-acyltransferases; Decanoic acid (PubChem CID:2969); Esterase; Ethyl acetate (PubChem CID: 8857); Ethyl decanoate (PubChem CID: 8048); Ethyl hexanoate (PubChem CID: 31265); Ethyl octanoate (PubChem CID: 7799); Hexanoic acid (PubChem CID: 8892); Higher alcohols; Isoamyl acetate (PubChem CID: 31276); Isoamyl alcohol (PubChem CID: 31260); Isobutyl alcohol (PubChem CID: 6560); Non-Saccharomyces; Octanoic acid (PubChem CID: 379); Saccharomyces cerevisiae; Wine aroma.
Pichia fermentans Z9Y-3 and its intracellular enzymes were inoculated along with S. cerevisiae in synthetic grape must to modulate fruity ester production The levels of ester-related enzymes, ester precursors, and fruity esters were monitored every 24 h during fermentation Results showed that the levels of Et acetate, acetate higher alc. esters (AHEs), short chain fatty acid Et esters (SFEs), and medium chain fatty acid Et esters (MFEs) were significantly enhanced in mixed fermentation Pearson correlation anal. further revealed that higher alcs. and fatty acids played a more important role in fruity ester production than enzymes; Particularly, the correlation coefficient between fatty acids and MFEs was 0.940. In addition, supplementation of medium chain fatty acids (7.2 mg/L) at the metaphase of single S. cerevisiae fermentation improved Et acetate, AHE, SFE, and MFE production by 42.56%, 21.00%, 61.33%, and 90.04%, resp., although the high level of Et acetate might result in off-flavors.
