    GelSpec - Gelatine Speciation

    gelatine speciation, gelspec, meat speciation, origin of animal products, halal

    Gelatine is prepared from the skin and bone material of a number of animal species, and is widely used in the food, confectionery and pharmaceutical industries. The ability to prove and safeguard ingredients in a fragmented and complex supply chain can be difficult. Combined with recent examples of food fraud and the infamous Horsemeat scandal in early 2013, public trust in the origins of food has been in decline. The correct identification of the animal of origin of animal products used in food, pharmaceuticals and animal feed is essential to ensure that these products meet legislative and labelling requirements.

    Gelatine is widely used in food and pharmaceuticals, manufactured from predominantly pig and cow, but also from poultry and fish tissue. The inclusion of certain gelatines in products can also raise ethical and religious concerns for consumers who wish to avoid these species.

    Want to know more about GelSpec - Gelatine Speciation Service?


    This new service is an in-house tested gelatine identification method. Using a large number of peptide biomarkers of animal origin, GelSpec is a more comprehensive method than other published methods. This method is incredibly accurate in identifying the origins of the gelatine using high resolution mass spectrometry to detect minute differences in the amino acid sequence of the gelatine peptides from different species.

    Our new GelSpec service uses high resolution LC-MS/MS - which detects multiple tryptic peptides as markers for confirmation - to identify the gelatine peptides from different animals of origin. Our newly developed and tested animal origin detection uses the most comprehensive method on the market in order to determine the animal origin (porcine or ruminant) of a finished gelatine or gelatine-based product. The method is based on highly sensitive mass spectrometry analysis of proteins in the products. We then apply a proprietary database of mass spectrometry data in order to specify the species of origin of gelatines and gelatines mixtures. During manufacture, collagen is hydrolysed to form gelatine which is a modified protein used in the form of sheets, granules or powder. Aspects of this manufacturing process often cause the species-specific DNA to become denatured which renders a polymerase chain reaction (PCR) method difficult or impossible. Since peptides are more robust to this process than DNA, our service uses LC-MS/MS - which detects multiple tryptic peptides as markers for confirmation - to identify the gelatine protein from different species. Our newly developed and in-house validated speciation detection uses the most comprehensive method on the market in order to determine the animal origin of a finished gelatine or gelatine-based product. The method is based on highly sensitive, high resolution mass spectrometry analysis of proteins in the products. We then use a proprietary database of mass spectrometry data, in order to specify the animal of origin (porcine or ruminant).
