Food processing which includes both fresh and packaged food involves handling of foods, preparation and storage through the subsequent stages so that the pathogens and toxic components present in food are destroyed and deactivated making the food safer and hygienic. It is the capability of the food processing sector to develop novel food processing and preservation technologies to manufacture and preserve food in an effective manner with a view to enhance their shelf life, improve quality as well as make them functionally more useful.

There is a large growing demand for novel food products which not only provide health & nutrition benefits and convenience to the consumers but also offer immense economic promise to the food processing industry and the farmers. This course “Novel Technologies for Food Processing and Shelf Life Extension ” deals about the recent and emerging engineering and technological innovations for novel and convenience food products manufacturing and shelf life extension. This course will play a pivotal role in pursuing research & development and will enable idea generation for the commercial manufacture of such products which ultimately lead our country to an international platform.
