Detection of Unknowns in Wine

In wine analysis, "unknowns" are compounds or substances present in wine but whose properties or concentrations are unknown. These unknown compounds can significantly impact the organoleptic properties of wine, such as flavor and aroma, as well as on the health and safety of the wine. The sources of unknown compounds in wine are numerous and complex due to various factors, including grape varieties and growing conditions, winemaking processes, microbial activity, contamination during production, accidental reactions between components, or the use of unauthorized additives. In recent years, there has been increasing interest in identifying and characterizing unknown compounds in wine, particularly those that may be associated with health benefits associated with moderate wine consumption.

Solutions

Identifying unknown compounds in wine can be challenging because thousands of different compounds may be present in wine, some of which may be present at very low concentrations. Our laboratory has a wide range of analytical techniques and trained professionals to detect and identify unknowns in wine. Lifeasible provides a one-stop solution for detecting unknown substances in wine to ensure that your wine is safe and meets the required quality standards.

We offer several analytical techniques that can be used to detect and identify unknowns in wine, including but not limited to:

• Gas Chromatography-Mass Spectrometry (GC-MS): In wine analysis, we offer GC-MS to identify unknown volatile compounds, such as aromas and flavors unknown non-volatile compounds, such as polyphenols.
• Liquid Chromatography-Mass Spectrometry (LC-MS): Our LC-MS technique is more suitable for analyzing unknown non-volatile compounds such as polyphenols and other antioxidants in wine.
• Nuclear Magnetic Resonance (NMR): We specialize in identifying unknown compounds such as organic acids, amino acids, and sugars in wine by NMR techniques.
• Fourier Transform Infrared Spectroscopy (FTIR): In wine analysis, we offer FTIR to identify unknowns such as sugars, acids, and phenolics.

Identifying and characterizing unknown compounds in wine is an essential area of research. We aim to help our clients identify and characterize unknown compounds in wine to improve our understanding of the complex chemical composition of wine and its potential health benefits. Our international level of testing has earned us the trust of many clients. If you are interested in our solutions, please contact us for a technical consultation and quotation.
