Hello Aspirant...... hope you're doing good..
Well, doing B.sc in any of the branches you mentioned have nearly same job opportunities in the near future. So it is basically upto your interest and desire to choose which branch. If you have passion for biological processes and have biology as a subject in senior secondary examination, then it's better to go for microbiology or bio technology rather than food processing. Micro biology has a lot of research work and you'd really enjoy this branch.
Hope this helps you out.....
Best of luck:)
