FoodScreener

Due to the separation of highly polar matrix constituents from less polar trace analytes and the increase in concentration, SPE is said to be of great benefit in the NMR analysis of water-based food samples such as juice and wine. This application note presents a method for automatic SPE extraction of red wine for NMR.

In this application note, the proven concept of the FoodScreener platform is extended in order to establish an NMR-based screening method for honey samples covering aspects related to authenticity, quality control and quantification. By combining targeted (quantification) and non-targeted (statistics for classification and verification) approaches, it is possible to address even more previously unsolved questions.

This application note shows how NMR spectroscopy can be used for identification and quantification of components in a naturel health product such as cinnamon, without additional separation or purification. The results from this method are highly reproducible and the method can be automated to save time and minimize errors.

The report in this application note details some of the compounds commonly found in commercial detergents. The study presents a comparison between major brands, and the “bargain brand” counterparts, using NMR to analyze the constituents qualitatively and quantitatively.

This application note demonstrates the suitability of nuclear magnetic resonance (NMR) for the unequivocal structural identification of illegal drugs and legal highs. The article demonstrates how DOSY experiments can be used along with computer-aided structure elucidation of the various compounds that make up synthetic drugs such as China White. It also shows how the structural information obtained can be used to streamline the identification and quantification of compounds present in recreational drug substances through the use of library search and matching tools.

Valued for the perceived benefit derived from their natural compounds, botanical extracts are key ingredients in nutraceuticals and personal care products. This application note demonstrates the procedure and the ability to automate the NMR analysis of goldenseal extract for use in botanical identity, evaluating identity and quantity of components and for quality control. Most previous researchers have used LC-UV methods to quantify berberine, canadine and hydrastine in goldenseal and lack highly compound specific information. NMR provides an information rich, fully automated, rapid assessment tool that enhances assurances of product composition.

Hear how scientists from the Hungarian Wine Consortium, comprised of Bruker and Diagnosticum, are working on an exciting initiative to prevent wine fraud. The program uses NMR FoodScreener technology from Bruker BioSpin to rapidly detect a ‘fingerprint’ of 53 different chemical elements in Hungarian wines which can then be used to identify and authenticate wines, providing information on vintage year, region of origin and wine type as well as any adulteration.
