Using an electronic nose and volatilome analysis to differentiate sparkling wines obtained under different conditions of temperature, ageing time and yeast formats was written by Martinez-Garcia, Rafael;Moreno, Juan;Bellincontro, Andrea;Centioni, Luna;Puig-Pujol, Anna;Peinado, Rafael A.;Mauricio, Juan Carlos;Garcia-Martinez, Teresa. And the article was included in Food Chemistry in 2021.Electric Literature of C10H18O2 This article mentions the following:
Effect of yeast inoculation format (F), temperature (T), and “on lees” ageing time (t) factors were evaluated on the composition of sparkling wines by a quant. fingerprint obtained from volatile metabolites and the response of an electronic nose (E-nose). Wines elaborated according the traditional method at 10 and 14鎺矯, free cells and yeast biocapsules formats were monitored at 15 and 24 mo of ageing time. Sixty-six volatiles identified and quantified in the eight sampling lots were subjected to a pattern recognition technique. A dual criterion based on univariate (ANOVA) and multivariate anal. (PLS-DA) through the variable importance projection (VIP) values, allowed to identify ten volatiles as potential markers for T factor, eleven for t and twelve for F factors. The discriminant models based on E-nose dataset enable a 100% correct classification of samples, in relation with t and F factors and the 83% for T factor. In the experiment, the researchers used many compounds, for example, 5-Hexyldihydrofuran-2(3H)-one (cas: 706-14-9Electric Literature of C10H18O2).
5-Hexyldihydrofuran-2(3H)-one (cas: 706-14-9) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Electric Literature of C10H18O2
