People suffering from celiac disease must avoid food containing gluten. In addition, a growing group of consumers stays away from gluten containing foods.
Producing healthy, tasty products that are gluten-free can be a challenge. Manufacturers producing gluten free food must assure their products meet legal requirements for gluten free food. Testing for gluten (gliadin) is a key element in quality control. We offer an extensive range of gluten test kits for quality control of your products.
Where to start with testing for gluten?
You can start by testing for gluten on surfaces in the production areas. Use a lateral flow test for gluten detection like the RIDA®QUICK Gliadin for swabbing surfaces. Bear in mind there might be also gluten traces in the laboratory. So before testing for gluten, check if your laboratory is free of gluten traces.
Choose the appropriate extraction method
After you have checked your production environment for gluten traces, test your raw materials and finished products for the presence of gluten. Effective extraction of gluten from the food is a crucial step in gluten analysis. Depending on the food matrix and test method selected, you can choose an ethanol extraction or use the patented Mendez cocktail extraction solution.
Use ethanol extraction in combination with the RIDASCREEN® Gliadin competitive or RIDA®QUICK Gliadin. Use the cocktail solution in combination with the RIDASCREEN® Gliadin, RIDASCREEN®FAST Gliadin or RIDA®QUICK Gliadin:
Which gluten test kit should I use?
Finally choose the appropriate gluten test kit for your products. Use the sandwich ELISA for testing most food products, use the competitive ELISA for testing fermented or hydrolyzed products like beer, syrups or sourdough and use the RIDA®QUICK lateral flow test for testing ingredients and raw materials.
All gluten test kits mentioned above are based on the R5 antibody (Mendez). Codex Alimentarius specifies in Codex Standard 118-1979 (2008) the R5 antibody based ELISA as the standard method for the determination of gluten. The RIDASCREEN® Gliadin ELISA and RIDASCREEN® Gliadin competitive are AOAC Official Methods of Analysis.
If you would you like to confirm the presence of gluten containing cereals in your products, our real-time PCR based test kits are the best option.
