GATE 2019 Syllabus for Food Technology

GATE 2019 – In their graduate fields, to test the performance and understanding capability of students Graduate Aptitude Test in Engineering (GATE) which is a national level exam is being conducted. In this test is useful for the admissions. On behalf of the  National Coordination Board, GATE exam is jointly conducted by the seven IITs (Indian Institute of Technology) and IISc (Indian Institute of Science)  – GATE, Department of Higher Education, Ministry of Human Resource Development (MHRD), Government of India. In many of the government and private organizations, the GATE score is important for recruitment. GATE score is compulsory for many private organizations.

About Food Technology

The branch of Engineering, Food Science, and Hotel management is called Food Technology. By food technology, some of the predominant parts of Science like chemistry, biology, engineering, nutrition, and microbiology are used extensively. It is a science which deals with the techniques and principles involved in processing and preserving the food substances are the science that is dealt with primarily. On food preservation, early scientific research into food technology concentrated. It is the application of knowledge to the food industry.
