Food is the main energy source for the living beings; as such food quality and safety have been in the highest demand throughout the human history. Internet of things (IOT) is a technology with a vision to connect anything at anytime and anywhere. Utilizing IOT in the food supply chain (FSC) is believed to enhance the quality of life by tracing and tracking the food conditions and live-sharing the obtained data with the consumers or the FSC supervisors. Currently, full application of IOT in the FSC is still in the developing stage and there is a big gap for improvements. The purpose of this paper is to explore the possibility of applying IOT for agriculture to trace and track food quality and safety. Mobile application for food freshness investigation was successfully developed and the results showed that consumer mobile camera could be used to test the freshness of food. By applying the IOT technology this information could be shared with all the consumers and also the supervisors. © Published under licence by IOP Publishing Ltd.
