A Computerised System for Monitoring Water Activity in Food Products Using Wireless Technologies

The food industry needs constant monitoring of both the technological process and the quality and safety of finished products. Control of the water activity value is essential to ensure the appropriate quality level of food products during their production because it affects the growth of bacteria and microorganisms, affecting the quality indicators, shelf life and proper storage of products. Modern enterprises must have an automated quality monitoring system. A specialised computer system for monitoring water activity should be an integral part of the overall quality monitoring system. This makes it possible to quickly react to deviations in the value of the water activity indicator and take preventive actions. The structural scheme of such a specialised computer system will be presented in this article. It is also important to correctly choose the type of water activity analyser based on the main parameters of the sensors, which are described in this article. The basic principles of developing the necessary software and a block diagram of the data flow algorithm in the system are also presented. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.
