'DETECTION AND NON-INVASIVE ANALYSIS OF MICROORGANISMS IN DAIRY PRODUCTS IN PAPER OR CARTON LAMINATED CONTAINERS USING ELASTIC WAVES BY DRY COUPLING'.

摘要

Non-invasive detection and analysis of microorganisms in dairy products in laminated paper or cardboard containers using elastic waves by dry coupling. The object of this patent is a procedure and a device for the early detection of the presence of microorganisms in foods, in particular in milk and its derivatives. One of its main advantages is that such detection can be performed inside its commercial containers without opening them. The presence of microorganisms is determined, before drastic changes occur in their physical properties, depending on the changes in the propagation of elastic waves (velocity, attenuation and harmonic distortion) through these products, and can also distinguish between Different types of microorganisms. For the realization of the detection it is done dry and precise in an environment with controlled humidity and temperature.
