This course will cover basics of dairy (liquid food) food processing and preservation technologies required in any dairy and food processing industries. The basic knowledge ondairy food processing is intermingled with most of the unit operations at some or other stage of processing. Since, this basic aspect of food processing and preservationis not taught in most of the Agricultural engineering institutions elaborately, a comprehension of these aspects of processing andpreservation will enrich the knowledge base of the students in general.INTENDED AUDIENCE :Agricultural Engineering, Food Technology, Food Engineering, Chemical Engineering, Biotechnological Engineering, Thermal Engineering, BiotechnologyPREREQUISITES :NILINDUSTRY SUPPORT :Any Processing Industry such as Britannia,ITC, Hindustan Lever, Mother Dairy, Amul, etc.
