Untargeted Metabolomics of Vinegar Using Quadrupole Time-of-Flight LC-MS

User Benefits

- The differences in the types and contents of flavor compounds and functional compounds in foods can be clarified using untargeted metabolomics with the LCMS-9030 quadrupole time-of-flight (QTOF) LC-MS. - The high mass accuracy of MS and MS/MS data, a feature of Shimadzu QTOF, enables highly accurate compound identification.

Introduction

Vinegar is a liquid condiment that is manufactured from saccharide-containing ingredients by alcoholic and acetic fermentation. Vinegar is made all over the world using various ingredients and manufacturing methods. Vinegar contains numerous compounds, including amino acids, saccharides, and organic acids. These compounds not only affect the flavor of vinegar but are also involved in biological regulation functions. Untargeted metabolomics, a method for comprehensively analyzing metabolites including unknown compounds, can reveal differences in the types and contents of flavor compounds and functional compounds in foods. This Application News describes an example of untargeted metabolomics of vinegar using the LCMS-9030 quadrupole time-of-flight (QTOF) LC-MS and the MS-DIAL program for untargeted metabolomics/lipidomics.
