Hello Anly,

As you should know that food technology is not a popular branch among all the branch in b.tech in Kerala as well as india.

You might get a starting salary package of 2.8 - 3.0 lac per annum if possible. 

Here I am mentioning the list of institute popular for food technology in kerala below :

• Cochin University of Science and Technology, Kochi
• Mahatma Gandhi University, Kottayam
• University of Calicut, Malappuram
• TKM Institute od Technology, Kollam
• Saintgits College of Engineering, Kottayam

Hope it helps. 

Thank  you :)
