My research will consist of the development of an online portable low-cost e-nose (OPLCEN) that can be used to enhance food safety in small industries in underdeveloped and developing countries such as Brazil. This device will make it possible for industries to stop adulteration at the food supply level as well as guarantee food’s freshness during the production line. An online and wireless system will allow the equipment to communicate with devices such as computers and cellphones, enhancing portability and facilitating the speed of evaluation. The steps of the research consist of designing the shape and hardware parts of equipment, followed by an integration system and data acquisition, such as artificial intelligence, that will be tested and implemented in the system to guarantee data accuracy. The goal is to provide an easy solution for small companies in Brazil to avoid food poisoning and waste, two major problems in the Brazilian food industry. The idea is that by using the OPLCEN system, small businesses not only save money but also help fresh food reach more people, which may help fight food deprivation.
