Dear Student ,

No , After doing B.Tech in Food Technology, you're not eligible to appear for GATE for pursuing M.Tech in CSE  .

This is because , there are certain rules about two paper giving examination in GATE :

• As per your Subject (Food Technology - XL- U ) , you are eligible to give combined paper exam in GATE only for the following subjects :

1. Biomedical engineering
2. Biotechnology
3. Chemistry
4. Ecology and Evolution

You can check the above information in brief details from here :
