M.Sc

Hi Pooja,
To be eligible in this course, the candidate has to be from science background and a minimum of 50% in the graduate and 12th level but this might also vary from institute to institute. The duration of the course in general is 2 years and is available in both full time and correspondence course. The tuition fee for this course varies from INR 20,000 to 30,000 depending on the institution. In terms of salary the dairy technology professionals receive a decent package in public as well as in private sectors. The starting salary varies from INR 20,000 to 25,000 and may go as high as 40,000 to 60,000 depending on the job profile.
I hope it helps.

Yes, you could choose between any life science courses you want. Assuming you have two reasons to change field:-
1. Thinking that no job opportunities for a Bachelor degree and/or for microbiology
2. Recently developed an interest in food technology, so you could pursue Ph.D or get a dream job in the same domain (or you decided to join with friends pursuing food technology).
However, if you still have interest in microbiology, there are definitely varied opportunities for microbiologists. Instead of doing M.Sc, you could do a job oriented Diploma course like certificate program in quality control microbiology, one such course is offered by the big player pharma company based in Bangalore.
Once after securing job and gaining few yrs of experience, where you have real experience to learn not just food tech but also about other career opportunities. Also to interact and learn from the scientists and team members. Well, you could take a call that time. You could quit job to follow your dream, of if you decided to do Ph.D, many companies like Biocon, Dr Reddy's offer research program for the employees.
Good luck!
