Degrees Offered: M.S. and Ph.D.
Associated Fields and Departments: The Food Science Graduate Group includes faculty from Food Science and Technology, as well as the Departments of Animal Physiology, Animal Sciences, Avian Sciences, Biological and Agricultural Engineering, Chemical Engineering and Material Science, Environmental Toxicology, Nutrition, Plant Biology, Pomology, Textiles and Clothing, Vegetable Crops, and Viticulture and Enology, and the Department of Pathology, Microbiology, and Immunology in the School of Veterinary Medicine.
Entrance Requirements: B.S. degree from an accredited institution with 3.0/4.0 GPA; GRE Verbal and Quantitative scores, original transcripts from all institutions attended (if not in English, official translation); three letters of recommendation; 550 on TOEFL examination (international students). Application deadline is April 1 (March 1 for international), however, applications are considered beginning in January. We admit students only for Fall.
Program of Study: The interdepartmental Graduate Group in Food Science offers programs leading to M.S. and Ph.D. degrees. Graduate studies stress application of biological, chemical, physical and behavioral sciences to the processing, preservation, quality evaluation, public health aspects, and utilization of foods. The M.S. degree is offered in five areas of specialization: chemistry-biochemistry, microbiology, engineering-technology, sensory sciences, and enology. Individually designed programs are also acceptable. For the Ph.D. there are three areas of specialization: biochemistry, chemistry, and microbiology. A Ph.D. degree in food engineering is available through the College of Engineering.
Degree Requirements: M.S. students can choose Plan I (minimum of 30 units with thesis) or Plan II (minimum of 36 units with research report and comprehensive oral examination). Ph.D. students take core courses as well as 15 units in their area of emphasis. Each student is appointed an academic advisor who in cooperation with the student's research professor assists in forming the student's study plan. Ph.D. students must pass a qualifying exam and complete an acceptable research dissertation. They must also take at least 6 units of seminar and give at least two oral presentations, including an exit seminar.
Statement of Costs: Application fee $40 (non-refundable). Tuition and fees per quarter are (approximately) $1,617 for California residents and $4,183 for non-residents.
Availability of Financial Aid: Research and teaching assistantships are available to all students on a competitive basis. For domestic students, limited university-funded fellowships and scholarship and Food Science Graduate Group funding are available. For international students, during the first year there are only limited possibilities for partial support from the Food Science Graduate Group and no university funding.
Unique Aspects of Program: The Graduate Group in Food Science has almost 50 faculty members, most of whom are also members of other graduate groups such as Biochemistry, Microbiology, Nutrition, Psychology and Chemical Engineering. Students therefore generally interact closely with students from several graduate groups. Besides the core program in food chemistry/biochemistry/microbiology there are special programs in enology, sensory science and brewing. Special strengths include structure-function studies of proteins, magnetic resonance imaging (MRI) of foods, edible films, food microemulsions, rheology, freezing, antioxidants, and microencapsulation.
