Grains & Bakery

What is the quality of your flour? TLR analyses your cereals, flour and bakery products and lets you know. Thanks in part to our close proximity to one of the most important grain ports in the European Union, we have extensive experience in quality analysis of cereals and cereal products.


In order to determine the quality of cereals and flour, TLR analyses moisture levels and assesses protein levels and quality. We use the Kjeldahl method and near infrared (NIR) techniques for this purpose. We can also develop specific NIR calibrations tailored to your preferences, and perform rheological tests with the alveograph. Other routine analyses include falling number, sedimentation level (Zeleny index) and detection of impurities, such as seeds, chaff or dirt (the ‘admixture’). TLR also offers a wide-ranging array of methods and tests for analysis of the nutritional content, composition, microbiological quality and safety of bakery products, from total germ count to specific tests for pathogens. For example, we can characterise salmonella within 36 hours. Moreover, TLR offers an extensive range of accredited analyses for identifying pesticides, mycotoxins, dioxins, heavy metals or PAHs. We help you maintain compliance with European quality standards such as GMP+, QS, GFSI, IFS and BRC, as well as HACCP. TLR has been approved by the Grain and Feed Trade Association (GAFTA) as an analysis laboratory


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.
