Qualifications
Energy is key here, because energy feeds gumption, and gumption becomes action. As we all well know, according to The Gumption Theorem: A=Ge^(Food). When it comes to more tangible qualifications, you'll definitely need more than a few things.
First, a college degree in food sciences, or a higher degree in a related field like chemistry or biology, or even business or international affairs, with some sort of food science-y background. You'll also need experience in the field, as well as some on-the-job training.
And, naturally, you should have people skills, organization skills, and problem-solving skills. These always come in handy. No matter what schooling you get, do make sure to have a background in chemistry, biology, biochemistry, or administration to apply to your work. Depending on the position, certain specific areas of experience, abilities, or foreign languages may also prove useful.
