The analysis and information extraction from to a growing use of sensor arrays in different fields, such as health monitoring, cell culture analysis, bio-signals processing, or food quality tracking. The analysis and information extraction from the the amount of data provided by these sensor arrays is possible based on Machine Learning techniques applied to sensor fusion. However, most of these computing solutions are implemented on amount of data provided by these sensor arrays is possible based on Machine Learning techniques applied to sensor fusion. However, most of these computing solutions are implemented on costly costly and bulky computers, limiting its use in in-situ scenarios outside complex laboratory facili-ties. This work presents the application of machine learning techniques in food quality assessment and bulky computers, limiting its use in in-situ scenarios outside complex laboratory facilities. This work presents the application of machine learning techniques in food quality assessment using a using a single Field Programmable Gate Array (FPGA) chip. The characteristics of low-cost, low single Field Programmable Gate Array (FPGA) chip. The characteristics of low-cost, low power power consumption as well as low-size allow the application of the proposed solution even in space consumption as well as low-size allow the application of the proposed solution even in space constrained places, as in food manufacturing chains. As an example, the proposed system is tested constrained places, as in food manufacturing chains. As an example, the proposed system is tested on an e-nose developed for beef classification and microbial population prediction. on an e-nose developed for beef classification and microbial population prediction. © 2021 by the authors. distributed under the terms and con-ditions of the Creative Commons At-Licensee MDPI, Basel, Switzerland.
