There are no placements for food technology at Karunya University. I personally know a few alumni of the university who were offered to shift their branch from food technology to any other branch because there were only 14 of them in that batch.
If you are really interested in food technology then, I would suggest you make a plan for higher studies before taking admission in the food technology branch of Karunya University. Also, do not rely on the university for placements. They only focus on placements of IT, CSE students. Overall, the average CTC offered at the institute is 3-4 LPA.
