A solution for analysing wine using nuclear magnetic resonance (NMR) spectroscopy was developed by Bruker with assistance from Winespin Analytics.
The principle of this method relies on acquisition of the spectroscopic fingerprint specific to each individual sample.
These profiles are compared to a large database of authentic wine samples using a multivariate statistical approach. Wine profiling by NMR combines quality control and testing of safety issues and authenticity.
Wine profiling has a range of features, including:
- Cost-effective, automated push-button NMR solution based on 400MHz including evaluation and reporting for comprehensive wine screening
- Reliable screening method providing targeted and non-targeted analyses from a single measurement
- Targeted analysis for all varieties and origins provides automatic quantification of 56 parameters per sample
- Quantification values compared to official reference values and to the concentration distribution of authentic samples supporting interpretation of the results
- Verification models to detect any deviation from authentic reference data in a non-targeted analysis approach
- Prediction of authenticity parameters of wine such as grape variety, geographical origin and vintage through classification analysis
