Summary/Abstract: Due to technological advancement and pollution, food quality is decreasing every day. Nowadays, some foods are highly processed. Excessive use of chemicals like preservatives, colourings, and flavours as additives in various foods can create big problems by accumulating them in the body. This uncontrolled use of additives can affect the health of consumers. In this case, the development of an electronic system that can measure the level or volume of additives added to food products and determine the degree of alteration of a food is absolutely necessary to ensure food safety. This paper proposes an embedded solution for food quality and freshness testing. Using a microcontroller and different sensors such as a gas sensor, pH sensor and moisture sensor, different values were measured in different food products. The measured values indicate important characteristics about the deterioration level of the tested food products. Based on the experimental testing of different thresholds, the developed system can provide the necessary information to decide whether a food product can be consumed or not, thus avoiding the commercialisation of dangerous food.
