"Aroma, Flavor, Fragrance" resources

Characterizing and understanding specific chemicals associated with aroma and flavors in a complex sample, like masala, can be beneficial for a wide range of purposes in the food, flavor, and fragrance industry. Among other objectives, detailed chemical information can be used for quality control, process optimization, reverse engineering of desired aroma characteristics, and to better understand a product/sample of interest. This application note demonstrates an easy workflow using statistical tools, and how a single GCxGC-TOFMS method can uncover a broad chemical profile that may be relevant to many unanswered analytical questions.

In this work, we explore the process of food spoilage by tracking the degradation of tomatoes. While this is a specific look at a tomato, an understanding of general food deterioration is important as spoilage impacts the quality and safety of food products and has significant financial implications. Until a process like this is well understood, evaluating the chemical profile and the changes is generally a non-targeted discovery task. For food spoilage, many of the changes that occur will be reflected in the volatile and semi-volatile components of the sample. The aroma profile of the sample itself changes, and chemical markers of microbial activity are also likely to form. GC and TOFMS are well-established techniques for these types of non-targeted characterizations of volatile and semi-volatile analytes and are well-suited for this type of investigation.

Complaints received by drinking water industries are often related to bad taste and/or unpleasant odors in drinking water. Most complaints involve the presence of chlorine or earthy/musty-smelling compounds. These issues can lead consumers to perceive the water as "unsafe", even though the substances causing the issues are typically not harmful. Reliable detection, identification, and quantification of the analytes behind these unpleasant tastes and odors in drinking water is essential for addressing these problems effectively. The Pegasus BTX GC-TOFMS system offers a solution to this challenge with the acquisition of full mass spectra even at concentrations below 50 pg/L, thanks to its exceptional sensitivity.

Joining us from the University of Messina, Mariosimone Zoccali, Assistant Professor of Analytical Chemistry, present on 'Boosting Food Analysis Using GCxGC-ToFMS. In his talk, Prof. Zoccali explores the pioneering applications of Comprehensive Two-Dimensional Gas Chromatography coupled with Time-of-Flight Mass Spectrometry in the analysis of extra virgin olive oil (EVOO), measured on our newly released Pegasus BTX GCxGC-ToF MS. He shows how this advanced technique provides insights in both targeted and non-targeted analyses , offering deeper understanding into EVOO's chemical profiles. Dr. Zoccali highlights how GCxGC-ToF MS enhances the detection of contaminants and key compounds, such as antioxidants and sterols, which are essential for assessing quality, authenticity and flavor.

Joining us from The Open University, UK, Dr. Geraint Huw Morgan, STEM Research Infrastructure Lead and Director of the Centre for Analytical Solutions, present an in-depth exploration of non-targeted screening techniques for complex aroma profiles. Drawing on his extensive experience in developing advanced methods for volatile organic compounds (VOCs), Dr. Morgan highlights innovative approaches and methodologies using advanced technologies like GCxGC-MS, and TOF-MS.

In this Application Note, we use comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GCxGC-TOFMS) and ChromaTOF Tile, a statistical analysis software for GCxGC data, to differentiate perfume samples.

The production of coffee and process development of new coffee variants and substitutes (caffeine free, alternative taste, and aroma profiles, etc.), is a huge industry globally. The ability to guarantee the safety of these products while also monitoring the flavour and aroma qualities of products to meet consumer expectations and preferences is vital. Here, a method for simultaneous analysis of Furans and Non-Target Screening (NTS) of other key compounds, such as aroma-active species, is demonstrated.
