DEVICE WITH A MICRO OR NANO MECHNICAL BASED SENSOR FOR DETECTION OF DECOMPOSITION MOLECULES LIKE BIOGENIC AMINES (ASSOCIATED WITH FOOD SPOILAGE AND CERTAIN HUMAN DISEASES AMONG OTHERS) AND SUBSEQUENT COMPUTATION FOR DETERMINATION OF FRESHNESS AND EXPIRATION DATE

摘要

The present invention constitutes a micro-or nano-mechanical fluid (gas or liquid) sensor for detection of biogenic amines associated with bacterial growth related to food spoilage and potentially in certain human diseases,water and air pollution. The sensor is part of a handheld, production-inline or real-time chip detection unit applicable in industry, retail and research and by private consumers. The measured values can be collected, stored and treated digitally in situ or at a remote location. The measured values will be compared to algorithms of pre-measured values in a database which reflect the decomposition rate of specific types of meat (i.e. beef, pork, fish, etc.) at certain storage conditions (i.e. temperature, atmosphere, etc.). From this comparison, the freshness of the specific meat or fish sample can be determined and a correct expiration date and remaining shelf-life predicted.
