Hello Vishnu,

Hope you are doing all good. Irrespective of your branch (Food Technology) you will fall under the umbrella of Engineers when you apply for CAT. Now, since you want an admission in IIM Ahmedabad, let me tell you that on IIM Ahmedabad does not offer specialized courses such as  Agri Business and Management at least at the PGDM level.

It provides you with a diploma in general management with which you can enter into any management field be it Agri Business and Management.

So to answer your question straight, Yes you can apply for CAT in order to get admission in IIM Ahmedabad being a Food Engineering student but rest assured you will have to clear the normal cutoff as of any engineer. No benefit will be given due to your background. However, your background and aspiration in Agri Management might be helpful during the PI.

Hope this was helpful.
