Edible codes for cheese – not another cheesey story…
Het Kaasmerk BV in, Leiden, the Netherlands, is a manufacturer of assorted blocks of cheese. Kassmerk has been collaborating with Isotron Systems on the traceability and quality control of its cheese for some time.Isotron Systems is the distributor of Cognex vision and identification equipment in the Netherlands. Kassmerk adopted a Cognex DataMan 7500 system to read the codes marked on its individual blocks of cheese.The two-dimensional codes are applied early in the production process and need to be read at the end of production.The only bar-code identification equipment Kaasmerk could find that was capable of working with the blocks of cheese, despite Kaasmerk’s rigorous industrial environment, was the In-Sight Vision System and the DataMan 7500 reader, which are both from Cognex.Identification codes, such as a 2D code or data matrix, are not only applied to state-of-the-art technology products, they are also applied to food products.These codes are mandatory in Europe, and are also necessary for safeguarding of food quality during production. They help minimise food-safety risks after the production phase, because each end product can be individually traced back to the production lot.Passport to traceabilityThe ability to identify each individual cheese as a unique item in the production chain is an essential component. Actually applied to the cheese block itself, the code functions as a veritable passport.
