172 / FIELDS OF INSTRUCTION Master of Science in Agriculture and Master of Agriculture. Programs leading to the degree Doctor of Philosophy with emphasis on problems related to food science may be obtained through the Departments of Fruit Crops and Microbiology with faculty members from food science directing the program. Areas of specialization are nutrition, food product and process development, food chemistry, food microbiology, food quality, and food safety. In addition to studies with the conventional agricultural commodities, the department has research projects with seafood. Prerequisite for admission to graduate study, in addition to the require- ments of the Graduate School, is a good scientific background. Students with insufficient background in chemistry, physics, mathematics, or microbiology will be required to take these prerequisite subjects without graduate credit.
