Unified flavor quantitation: Toward high-throughput analysis of key food odorants and tastants by means of ultra-high-performance liquid chromatography tandem mass spectrometry was written by Hofstetter, Christoph Konrad;Dunkel, Andreas;Hofmann, Thomas. And the article was included in Journal of Agricultural and Food Chemistry in 2019.COA of Formula: C6H12O2 This article mentions the following:
Because foods are perceived through combined inputs from taste and odor, which are determined by the concentration of the individual odor and taste mols., the unified high-throughput quantitation of volatile odorants and non-volatile tastants with the very same instrumental setup has been a long-standing but yet unmet dream. The research presented here for the first time demonstrates, after only minimal sample workup, the highly accurate, rapid, and sensitive unified quantitation of odorants and tastants of key flavor mols. in apple juice on a single ultra-high-performance liquid chromatog. tandem mass spectrometry (UHPLC-MS/MS) platform over a large dynamic range of up to 6 orders of magnitude. While flavor-active aldehydes, ketones, and organic acids were analyzed after derivatization with 3-nitrophenylhydrazine, taste-active polyphenols and odor-active esters were directly analyzed by means of UHPLC-MS/MS with and without target analyte enrichment through stir-bar sorptive extraction This “unified flavor quantitation” approach holds promise to accelerate the transition of today’s labor and time-consuming, low-throughput anal. of odorants and tastants into a new era of high-performance quantitation of key flavor mols. In the experiment, the researchers used many compounds, for example, Methyl2-methylbutyrate (cas: 868-57-5COA of Formula: C6H12O2).
Methyl2-methylbutyrate (cas: 868-57-5) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. 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.COA of Formula: C6H12O2
