PhD is completely different from bachelors and masters by the requirements
Level of your expertise and in depth knowledge in subject you want to research on
Availability of infrastructure, amicable environment in research place, department, institute, etc.,
Proper guidance and recognition from the research guide.
In India, key and important factor to pursue PhD is your research guide
Let me, list the best institutes I get from top of the mind..
There are various state level universities and agricultural institutes working on post harvest and food Technology such as,
Tamil nadu agricultural university in Coimbatore
The choice of the best institute for you may vary depending on the research topic you want to pursue rather than just receiving a PhD degree from best institute.
Regarding my personal exposure and experience, I have felt that:
Cornell university, USA
Purdue university, USA
Helsinki university, Finland
Lund university, Sweden
RMIT university, Australia
Nottingham university, UK
Aarhus university, Denmark
Copenhagen university, Denmark
I have listed some of the American and European universities that are frequently seen in the research fields. However there are numerous universities and professors pioneering in specialised topics within the broad scope of food science and technology.
Some of the Asian (Chinese, Japanese, etc) universities are researching increasingly in food science and technology in the recent decades.
The best institute again depends on the research topic or field you look for, infrastructure and amicable environment with good guides/professors.
