Hello Subbu,

Food processing is considered as a lower branch in all the colleges and if seen from the practical aspect , in india there is very less scope in the food processing stream or in the horeca buisness.

If you want to pursue this career then i would recommend you to kindly look for abroad colleges for your post graduation and if possible kindly change your branch.

But also keep in mind if you are not able to change your branch then it doesn't mean it's a waste doing this degree. After all you are in iit and there are many companies which allows for non core stream even from this branch.
