In food we trust – the passion of food analysis

 

Advanced beer aroma analysis

Erich Leitner, TU Graz, Institute of Analytical Chemistry and Food Chemistry, Graz, Austria

Beer is a complex alcoholic beverage, containing several hundred volatiles and flavor active compounds. The concentrations cover a huge range from picogram to milligram per liter which makes the analysis really challenging. The main constituents of beer are water, ethanol, carbohydrates, proteins and carbon dioxide, but in terms of sensory perception the minor constituents are the relevant ones. They derive from the used raw materials or are formed during the brewing process or storage of beer. The impact of the raw materials (barley, hop) and the processing steps (mashing, fermentation, hop isomerization) and their impact on the final product quality will be discussed in this presentation. Further on analytical strategies from sample preparation procedure to targeted and untargeted analysis of volatile and aroma active compounds using different one and two dimensional gas chromatography based methods (GC-MS, GC-MSMS, GCxGC, MDGC) will be shown. Finally relevant off odor compounds will be discussed in detail in terms of source, formation and analytical determination.

Characterization of the Oxygen Heterocyclic Compounds (Coumarins, Psoralens and Polymtehoxylated Flavones) in Food Products

Oxygen heterocyclic compounds were identified by using an HPLC-PDA/MS/MS system equipped with an APCI source in positive ionization mode, in a single run in less than 10 minutes. The MS/MS transitions obtained at a defined collision energy have been used to build a library. The use of an MS/MS system allowed to achieve limit of detection and quantification (LOD and LOQ) in the ppb range, thus making the method very useful for food industries. Furthermore, the goal of the present research was to propose an easier to use method for the characterization of the oxygen heterocyclic compunds in food, by using a simpler HPLC-PDA instrument and the internal standard/response factor approach. Psoralens are a class of photoactive compounds found in several plant species and maybe responsible for the observed association between consumption of citrus products and the risk of phototoxicity.

How Safe is Safe? Analytical Tools for Tracing Contaminants in Food

Uwe Oppermann, Anja Grüning, Gesa Schad, Carola Schultz, Shimadzu Europa GmbH, Duisburg, Germany

Contaminants like pesticide residues, mycotoxins and heavy metals may occur in our food from a variety of different sources. These are in the focus of European food and safety authorities, and are controlled by national and international regulations. Analysis of relevant chemical contaminants is therefore an essential part of the food safety policy of the European Commission to ensure the highest level of protection of human health. Modern hyphenated analytical techniques such as chromatography (LC-MS), spectroscopy and mass spectrometry can determine these contaminants in complex food matrices with high sensitivity at ultra-low concentration levels in order to keep the food and beverage chain safe.

Product Lineup

 

In only 14 minutes, this mycotoxin screening system is able to detect the presence of 10 mycotoxins with LOQs matching EU regulations. The system does not require sample derivatization, for highly efficient sample measurement. It offers the high performance and user friendly handling of the established i-series compact LC system with additional features to help the unexperienced user.

Shimadzu’s MOSH/MOAH analyzer puts manufacturers of food and food packagings on the safe side. The MOSH/MOAH analyzer has been designed specifically for sensitive and fast detection of mineral oil contaminations based on the draft version on the  European Norm 16995:2017. The system combines LC and GC technology with flame ionization detection (FID) for a highly efficient analysis covering preparation, pre-separation and automated processes.

In addition to being a “green technique” with a decreased usage of toxic organic solvents SFC also offers an increase in the range of compounds that can be analysed by a single method. Experiments have shown that, not only can SFC-MS/MS be used to separate numerous pesticides with a wide range of different polarities simultaneously, also a marked increase in sensitivity for a large number of compounds was achieved. Due to the intrinsic, universal sensitivity and specificity of the LCMS 8060 Triple Quadrupole Mass Spectrometer and the versatility of the Nexera UC/s LC/SFC switching system, the combination offers an attractive alternative to the conventional LC-MS approach.

The LCMS-8060 triple-quadrupole mass spectrometer is designed to push the limits of LC-MS/MS quantitation for applications requiring the highest sensitivity and robustness while delivering reliable data for routine food analyses. Due to the intrinsic, universal sensitivity and specificity of the LCMS-8060 and the versatility of supercritical fluid chromatography technique, the combination offers an attractive alternative to the conventional LC-MS approach. Experiments have shown that SFC-MS/MS can be used not only to separate numerous pesticides with a wide range of different polarities, but also to achieve a marked increase in sensitivity for a large number of compounds.
