Prerequisites to Master of Science Degree Program: The student must have a B.S. degree from an accredited institution with a grade-point average of no less than 3.0, suitable preparation in food science or related areas and be acceptable to the department.

Requirements for the Master of Science Degree: Aside from deficiencies, a minimum of 24 semester hours of course work and 6 semester hours of thesis are required for the M.S. degree. At least 12 course credits of the 24 credits required must be from 5000 or higher level courses. In addition to coursework, the student will be required to conduct research and prepare an acceptable thesis. Upon admission to this program the candidate will be assigned to athesis director, who in consultation with the department head will select a graduate committee. This committee will assist with developing a suitable program for the candidate and will serve as the examination committee.

Prerequisites to Doctor of Philosophy Degree Program: Applicants for acceptance into the interdepartmental doctoral program in food science must meet all of the requirements for admission to the Graduate School and the Department of Food Science. Applicants must have a thesis M.S. degree in food science or a related area from an accredited institution, suitable academic preparation in food science and related physical and biological science and a minimum grade-point average of 3.0 in all previous graduate work.

Requirements for the Doctor of Philosophy Degree: Upon acceptance to this program, the student will be assigned to a dissertation director from the department representing the student's selected area of concentration. The dissertation director in consultation with the student and with the department head will select at least two suitable graduate faculty members from outside the student's own department to complete a committee of five members.
