<p>Not many undergraduate schools offer Food Science, so would I be able to major in Biochem and do Food Science in graduate school? </p>
<p>That really depends. Your major does certainly matter in most respects. If one wants to go to grad school for physics, one needs to major in physics during their undergrad. There are instances of engineering or mathematics students going to grad school for physics (and vice-versa), but that puts a student at a distinct disadvantage because they have to spend the first few semesters catching up on the stuff that they’ve almost certainly missed, before getting into the graduate courses that they should be in. </p>
<p>Something like biochem to food science would likely be doable. It’s going to depend greatly on what types of requirements graduate schools look for in a good science applicant. </p>
<p>Check the graduate programs in the desired graduate major to see what their expectations of undergraduate preparation are.</p>
