Molecular mechanism of high pressure shear grinding on Feng-flavour Chinese Baijiu ageing was written by Jia, Wei;Fan, Zibian;Du, An;Shi, Lin. And the article was included in Food Research International in 2022.SDS of cas: 106-79-6 This article mentions the following:
Ultrahigh-pressure homogenization is a powerful technique for accelerating Baijiu ageing. In this study, the mol. mechanism of artificial ageing was thoroughly investigated utilizing foodomics combined with a mass spectrum information optimization program. Various characterizations of compounds in the ageing process were performed through ultra high performance liquid chromatog. quadrupole-orbitrap high resolution mass spectrometry (UHPLC-Q-Orbitrap) based colloid theoretics. High-pressure shear grinding provides a high-pressure and high-temperature environment for Baijiu, accelerating the formation of flavor compounds and the decomposition of odor and harmful substances, thus improving the sensory characteristics of Feng-flavor Baijiu and shortening the ageing time. A total of 2069 substances were identified according to fragment spectra and Bayesian network model-based peak distribution. Mols. with VIP > 1, including 14 esters, 10 acids, 4 ketones, 3 aldehydes, 2 alcs. and 2 phenols, were quantified as potential markers of chemometric anal. A novel prediction model for Baijiu ageing degree was furnished, and ageing years of Feng-flavor Chinese Baijiu were accurately predicted by factor anal. with KMO 0.784 and a polynomial regression model with r 0.94. The results demonstrated that in 400 bar, fresh distilled Baijiu could reach a natural ageing effect of 6.43 years, which was consistent with the sensory evaluation. In the experiment, the researchers used many compounds, for example, Dimethyl decanedioate (cas: 106-79-6SDS of cas: 106-79-6).
Dimethyl decanedioate (cas: 106-79-6) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.SDS of cas: 106-79-6
