Oils & Fats

Do you need to know the quality and composition of specific oils and fats? TLR can determine and quantify key quality parameters and components of oils and fats. That includes the fatty acid profile and levels of free fatty acids, tocopherol, cholesterol, lecithin, peroxide and water.


TLR also offers a wide range of analyses to identify residues and contaminants, such as pesticides, mycotoxins, heavy metals, or polycyclic aromatic hydrocarbons. Detecting the presence of dioxins is an important step in risk management. The same applies to traces of GMOs and fat-soluble components that have migrated into food or feed from the packaging, for instance mineral oils. Our analysis services can help you maintain compliance with food safety standards like IFS and BRC, as well as the HACCP analyses that are required by law. TLR is accredited by the Federation of Oils, Seeds and Fats Associations (FOSFA) and the Netherlands Oils, Fats and Oilseeds Trade Association (NOFOTA) and qualified to analyse oilseeds and derivative products. As a member of FEDIOL, the EU vegetable oil and proteinmeal industry association, TLR supports the mission to assure the quality and safety of oils, fats and related products.


TLR is ISO 17025-accredited (L059), QS-certified and approved by the FOSFA, FEDIOL and GLOBAL GAP. In this way we help your organisation to comply with (international) guidelines, such as the VLOG certification.
