Thermal Processing of Foods

By Dr. R. Anandalakshmi   |   IIT Guwahati
The Food and Agriculture Organization (FAO) of the United Nations (UN) issued a report on the importance and complexities associated with feeding the projected 9.1 billion world population in 2050. Sustainable production of safe and nutritious foods, development of foods that have a long shelf life and foods that are either ready-to-eat or easy to are of greater importance towards meeting this goal. Understanding “Food Engineering” and “Thermal Processing of Foods” serves as basic requirement means of meeting this goal.

INTENDED AUDIENCE: The target audience for this course is 

(i)        BTech/MSc/MTech/PhD students or faculties from reputed academic and technical institutions interested in acquiring knowledge of thermal food processing technologies
