Biochem vs. Mol Bio vs. Chem engineering

<p>Hey guys. I really like chemistry and food and was looking for a field in which I can combine these two passions (i understand that food will be a very,very minor part of this but maybe it could be a part of research in my future). Could someone explain the differences in these majors in terms of topics covered, courses taken, general difficulty (i know this varies based on where I go but idk if there are any differences in difficulty between these fields across the board). Thanks!</p>
