Can we perform gelatin speciation and adulteration using bioinformatics, proteomics and high resolution mass spectrometry?
About this webinar
Gelatine is composed of highly processed proteins, which is widely used as a gelling and thickening agent in a variety of food products, including meat, confectionery products and water-based desserts. It is also widely used in the pharmaceutical industry. Gelatine is obtained by hydrolysis of collagen, which is extracted from materials such as bone, hide and skin from animal slaughterhouses. Nearly 80% of gelatine are produced from pig by-products. However, vegetarian, Halal and Kosher gelatine, are normally prepared from seaweed, fish or bovine skin or bones.
The webinar will present a strategy to detect specific peptide biomarkers in the digested gelatin and food samples using HPLC–QqOrbitrap. We will also demonstrate that this method can be an effective strategy to detect gelatine adulteration.

Dr Beaudry received his bachelor’s degree (chemistry) from Sherbrooke University (Sherbrooke, Canada) and his doctorate (medicinal and analytical chemistry) from the Anglia Ruskin University (Cambridge, UK). He has completed 2-year research assignment in proteomics/peptidomics at Univeristé de Montréal prior his appointment as associate professor in June 2009. Since June 2009, he has supervised or co-supervised 19 MSc and PhD students and he is the author or co-author of 93 peer reviewed manuscripts and 90 research abstracts. He has received in February 2017 The Faculty of veterinary medicine of the Université de Montréal / Zoetis award for excellence in research.
In recent years adulteration has become an increasing problem globally in the food industry and for consumers. Determining if the product has been adulterated is important for many reasons. Is the product pure; does it contain any contaminants; has it been adulterated in any way for economic reasons?
Thermo Fisher Scientific has advanced instrumentation that can help in the area of food adulteration to determine the known and unknown contaminants of the food and beverage product. Their state of the art products help labs check for the adulteration of edible oils to fruit juices and many other products. Their instruments help government agencies and contract laboratories determine if a particular product has been adulterated.
