Comparative investigation of volatile components and bioactive compounds in beers by multivariate analysis was written by Ji, Xiaoyue. And the article was included in Flavour and Fragrance Journal in 2021.Name: Octyl acetate The following contents are mentioned in the article:
The volatile components of nine com. beers were characterized by headspace-solid-phase microextraction (HS-SPME) coupled with gas chromatog.-mass spectrometry (GC-MS). Multivariate anal. was conducted to evaluate the similarities and differences between the volatile components and bioactive compounds present in the target beer samples. Thirty-eight volatile compounds were identified, and their chem. categories were determined Alcs. and esters were determined to be the predominant volatile components in samples. The differences and classifications of the beer samples were analyzed through principal component anal. and cluster anal. The anal. of the volatile compounds in beer samples revealed that the type and content of the volatiles can influence beer quality and taste. The combination of SPME-GC-MS and multivariate statistical anal. proves to be an effective approach for differentiating beer types and for allowing the quality control of beer. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Name: Octyl acetate).
Octyl acetate (cas: 112-14-1) 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. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Name: Octyl acetate
