The research is focused on various aspects of food security in developing countries. The most important part of the research is oriented on food processing technology and its applicability in developing countries in order to ensure sufficient production of good quality and healthy foods. The priority of our research is the preservation of food using economically viable techniques based on renewable energy sources (e.g .solar drying, solar cooking) as well as the use of natural compounds as food preservants. Other part of the research is dedicated to the monitoring of different socio-economic aspects influencing food security (e.g. agriculture practices, land tenure systems, agriculture policy), including the evaluation of the quality of food produced in developing countries.
