Hello Aryan,

As in general therevis no exam for becoming a food scientist,all you need to do is hold a bachelors and masters degree in food technology and then apply for ph.d/scientist degree.Apart from that if you want to become a certified food technology specialist then there are various institutions/organisations providing it.

Though there are no 'military scientist' position in Indian army,once can serve army by becoming a scientist.All you need to do is to get a descent GATE score and then get interview call from DRDO.There will be hell lot of competition for this position.But it will be worth it.

All the best 

Feel free to ask if you have any further queries.
