The Department of Food Technology and Rural Industries, one of the five constituent Departments of the Faculty of Agricultural Engineering and Technology, started functioning since 1964. The Department is housed in the ‘Najmal Haque Bhabon’ in the premises of the Faculty of Agricultural Engineering & Technology. The Department offers most of the professional courses for the award of Bachelor of Science in Food Engineering (B.Sc. Food Engg.) degree under the Faculty of Agricultural Engineering & Technology and the first batch of the graduates came out in 2006. It may be mentioned here that the Department used to offer several courses under the integrated curriculum for B.Sc. Agri.Engg. degree. The department also offers M.S. and PhD degrees.

The formal components of the food engineering program provide integrated professional training in food science and technology with emphasis on the engineering aspects. The course is formal and elective in nature providing an opportunity for students to apply their basic skills in areas relevant to this field.

The studies in food engineering are designed to strengthen the engineering background and emphasize the use of fundamental principles in solving problems associated with food processing industries as well as other post-harvest operations of raw materials from plant, animal and marine sources. The food engineering is a combination largely of chemical and mechanical engineering which is based on chemistry, mathematics, physics and mechanics, applied to foodstuffs, their production, processing and preservation. Hence the physical and biological properties of food materials are the important criteria for unique consideration of engineering principles applied to food. A food engineer, among other functions, is capable to design and develop processes and equipment required for food processing industries.

By virtue of professional orientation the graduates in Food Engineering and M.S. in Food Technology and Food Engineering are well-suited to serve education and research institutions, Directorate of Food, Directorate of Agricultural Extension, food and agro-industries of the government and non-government organizations.

All academic matters of the Department are administered through its Board of Studies which consists of the teachers of the Departments, and one expert member nominated by the Vice-Chancellor of the University. For further information, contact Head of the department at:
