LCGC recently spoke to Miguel Herrero of the Institute of Food Science Research (CIAL-CSIC) at the Spanish National Research Council, in Madrid, Spain, about his research in foodomics-based approaches, the evolution of food analysis, and the benefits of two-dimensional (2D) liquid chromatography (LC) in this application.
This application note demonstrates how comprehensive 2D-LC can be used to resolve the complex mixture of hydrophilic phenols found in virgin olive oil and investigates differences in the phenol composition of several olive oils.
Kate Mosford of The Column spoke to Rosa Perestrelo of Centro de Química da Madeira located in Madeira University, Portugal, about wine analysis. She reveals the science behind winemaking and offers her tips for selecting the best analytical method.
Vicinal diketones (VDKs) are naturally produced compounds in the fermentation process. The monitoring of VDK levels is of great importance as the concentration of these compounds can greatly alter the flavor of a beverage.
