Ainia Develops tecnologia to detect metals and glasses in foods

You trace of metal, rests of glass or of plastic in foods are each true time detected by the consumer, with the consistent withdrawal of the product of the market. They are the called odd matters, extraneous elements to the ingredients of an alimentary product that are used to to proceed, in a lot of occasions, of the raw materials or of the same surroundings in which it is processed the food.

In an alimentary industry like the European where the levels of control are increasingly demanding, how can inspect the foods to verify, before they arrive to the consumer, that do not contain odd elements? His fast detection and the increase of the hygiene and quality of the foods is one of the worries of the sector, of the consumer and of the authorities.

Now, Ainia technological centre, after five years of investigation, has attained to develop a new technology applied to the able alimentary industry to obtain a map of composition in real time of the product that is processing . A revolutionary technology based in the spectral vision that allows to go further of the limitations that have the systems of conventional inspection like the X-rays, that only are able to detect matters of high density.

The food produced is lit with infrared lamps whereas a camera attracts images of the product that are processed by a system of computation of high provision that, by means of logaritmos advanced, transforms it in chemical images. That is to say, it identifies of what is composed the food and which is his concentration: which quantity of proteins, humidity, fat or sugars contains, or for example, which is the degree of maturity of the fruit. To his time, the technology allows to detect with a lot of greater possible precision odd matters like metals, plastics, bones, vegetal rests, etc. that they can appear in the food during his production, for example in nuts, elaborated cárnicos or ready dishes. In this way, the new technology has a big applicability to improve and optimise processes of manufacture, as well as in the improvement of the control of quality and hygiene in the prime matter or in the final product.

This technology can apply to any product reducing costs of inspection and production, improving like this the efficiency and alimentary hygiene when checking in 100% of the production of an alimentary company, of form much faster and reliable, that a product is safe. Ainia Is the first centre in Spain that has the capacity to apply this technology in real time covering all the near infrared spectrum.
