Diez-Ozaeta, Inaki published the artcileWine aroma profile modification by Oenococcus oeni strains from Rioja Alavesa region: selection of potential malolactic starters, Application In Synthesis of 123-29-5, the main research area is Oenococcus wine aroma fermentation Spain; Biogenic amines; Hydroxycinnamic acids; Malolactic fermentation; Oenococcus oeni; Tempranillo wine; Wine aroma compounds.
Previously six selected Oenococcus oeni strains (P2A, P3A, P3G, P5A, P5C and P7B) have been submitted to further characterization in order to clarify their potential as malolactic starters. Laboratory scale vinifications gave an insight of the most vigorous strains: both P2A and P3A strains were able to conclude malolactic fermentation (MLF) in less than 15 days. The remaining strains showed good viability and were able to successfully finish MLF in the established anal. time, except for the strain P5A, which viability was totally lost after inoculation. Also spontaneous fermentation was not initiated. None of the strains was biogenic amine producer; however, P5C strain significantly increased the concentration of volatile phenol-precursor hydroxycinnamic acids after MLF. Regarding the evolution of wine aromatic compounds, main changes were detected for both Et and acetate esters after MLF; however, key aromatic compounds including alcs., terpenes or acids were also found to significantly increase. Principal component anal. classified the strains in two distinct groups, each one correlated with different key volatile compounds P2A, P3A, P3G and P5C strains were mainly linked to esters, while P7B and the com. strain Viniflora OENOS showed higher score for diverse compounds as hexanoic acid, β-damascenone, linalool or 2-phenylethanol. These results confirmed the specific impact of each strain on wine aroma profile, which could lead to the production of wines with individual characteristics, in which the reliability and safety of MLF is also ensured.
International Journal of Food Microbiology published new progress about Fermentation. 123-29-5 belongs to class esters-buliding-blocks, name is Ethyl nonanoate, and the molecular formula is C11H22O2, Application In Synthesis of 123-29-5.
