Wei, Jianping published the artcileChemical composition, sensorial properties, and aroma-active compounds of ciders fermented with Hanseniaspora osmophila and Torulaspora quercuum in co- and sequential fermentations, Category: esters-buliding-blocks, the main research area is aroma compound fermented cider Hanseniaspora Torulaspora; 3-Methyl-1-butanol (PubChem CID: 31260); 3-Methylbutyl acetate (PubChem CID: 31276); Ethyl butanoate (PubChem CID: 7762); Ethyl hexanoate (PubChem CID: 31265); Ethyl octanoate (PubChem CID: 7799); Gas chromatography-olfactometry (GC-O); Glycerol (PubChem CID: 753); Hanseniaspora osmophila; Mixed fermentation; Partial least squares regression (PLSR); Phenylethyl alcohol (PubChem CID: 6054); Torulaspora quercuum; dl-malic acid (PubChem CID: 525); β-Damascenone (PubChem CID: 5366074); β-Phenethyl acetate (PubChem CID: 7654).
In this study, apple juice was fermented using Hanseniaspora osmophila X25-5 in pure culture as well as mixed culture with Torulaspora quercuum X24-4, which was inoculated simultaneously or sequentially. H. osmophila inhibited the growth of T. quercuum, while T. quercuum had little effect on the growth of H. osmophila. The simultaneous fermentation consumed relatively more sugar and resulted in the highest ethanol content. The production of organic acids varied depending on the yeast species employed and inoculation modality. Esters and alcs. were the main volatile families produced during fermentation, while Et esters and terpenes contributed most to the temperate fruity aroma. Gas chromatog.-olfactometry (GC-O) showed that 3-methyl-1-butanol, Et 2-methylbutanoate, phenylethyl alc., β-phenethyl acetate, and β-damascenone were the most potent odorants in all samples. This study suggested that simultaneous fermentation with H. osmophila and T. quercuum might represent a novel strategy for the future production of cider.
Food Chemistry published new progress about Apple juice. 106-32-1 belongs to class esters-buliding-blocks, name is Ethyl octanoate, and the molecular formula is C10H20O2, Category: esters-buliding-blocks.
