Chem Nutri Analytical is proud to be the first—and only—laboratory in Africa (and possibly the world) to achieve ISO/IEC 17025 accreditation for Trypsin Inhibitor Activity (TIA)—a milestone that affirms our role as the authoritative lab for soya quality testing and dispute resolution.
Traditional methods such as Urease Activity (UA), Protein Dispersibility Index (PDI), and KOH solubility remain important tools for assessing soybean meal quality, especially in operational environments. However, these methods demand a high degree of accuracy—making testing in an accredited laboratory essential.

While useful for screening, only TIA provides a direct and precise measurement of anti-nutritional factors, setting a new benchmark for quality assurance in soya analysis. In many cases, when TIA data drives key decisions, our signature is already there — quietly ensuring quality. Don’t settle for less—present an authoritative, accredited result in every dispute. At Chem Nutri, we put you First.
