DRDO Scientist B (Food Science) official syllabus guide
DRDO Scientist B (Food Science) syllabus 2027
RAC shortlists Scientist 'B' candidates on GATE scores and then holds a written test or an interview. For food science in 2022 the GATE paper was Life Sciences (XL): General Aptitude, the compulsory Chemistry section and an optional section, where food candidates take Food Technology (XL-U). Prepare that paper with the site's GATE XL mocks (/exam/gate-xl); the interview goes deeper into your master's subject and defence food applications such as ration packs, shelf-stable and high-altitude foods.
