Hello Praveen Kumar,

    I understand your concern and I am here to help you regarding your query and take you forward !!

  As per my opinion, Chemical engineering would be the best as it offers research and working in industries too. As a chemical engineering graduate, you can also have chance of process engineer, maintenance, research field and many more. Although, food technology is least preferred and it has scope as a food scientist or any other research fields. Anyways, chemical engineering has the highest scope when compared with food technology.

Hope you find my answer helpful !!

All the very best wishes for your future endeavours !!
