Abstract
Marine ingredients are increasingly used in the food and feed industry, and their composition require analytical control to ensure they meet safety and quality requirements. Chromatographic techniques play a central role in detecting environmental toxins such as PCBs, dioxins, and heavy metals, which must remain below regulatory thresholds to protect the end consumers, both humans and animals. In addition to contaminant screening, content of key nutrients, such as Omega-3 fatty acids, proteins, vitamins and minerals, must be accurately measured to ensure correct labeling and to meet the requirements of the food and feed manufacturers. Oxidation of unsaturated fatty acids in marine ingredients is susceptible to oxidation, which affects sensory quality and can lead to rancidity. Testing for oxidation products is important to ensure freshness and adequate shelf life of marine ingredients.
The analytical instrumentation platform at SINTEF Industri in Trondheim includes instrumentation for GC-MS/MS, GC-FID, LC-MS/MS and ICP-MS, covering most aspects of organic and inorganic analysis. The research group performs analysis related to the composition of feed ingredients, raw materials and finished products. The research group performs accredited analysis of PCBs, dioxins, furans and heavy metals in biological material and ingredients of marine origin, and water determination using Karl Fisher titration.
In this poster, examples of important analysis for monitoring of feed quality and safety, including the analysis of unwanted impurities and contaminants, performed at SINTEF Industry in Trondheim will be presented.
