TThe Department of Food Science offers research-based MSc and PhD programs and the course-work-based collaborative MSc in food safety and quality assurance. The department's primary fields of study are food chemistry (Dalgleish, Kakuda, Marangoni, Mine, Swatland, Yada), food microbiology (Griffiths, Schraft), and food processing/engineering (Barbut, Goff, Hill, LeMaguer, Lencki).

Msc Program

The MSc program focuses on various aspects of food science. Students have the opportunity to apply scientific and engineering principles to the production, processing, preservation and utilization of food.

Admission Requirements

To be considered for admission, applicants should hold an honours baccalaureate degree with at least a `B-' average during the last two years of study. To assist in identifying a suitable thesis advisor, applicants should submit a short statement of research interests. Supportive letters of reference are essential and should outline the applicants' strengths and weaknesses. Students may be admitted into the fall, winter or spring semesters.

Degree Requirements

MSc students are required to register in at least four graduate courses (a minimum of 10 credits) and prepare an acceptable thesis. A graduate degree program form signed by the student and approved by the student's advisory committee will be submitted during the first semester for approval of the departmental graduate studies committee. The students must maintain a minimum 'B-' average to remain in the program. In addition, each student is required to take a seminar course which provides training in technical communications. The thesis research is planned by the student in consultation with the advisor and approved by the advisory committee during the first semester of the program. The program is completed by the successful defence of the thesis.

PhD Program

The PhD program focuses on the fields of food chemistry, food microbiology, and food processing and engineering. The heart of the PhD degree is an independent research project leading to a written thesis which must be defended before the graduate faculty. The program is a demanding one, providing both intellectual challenges and opportunities to those highly motivated students wishing to advance their knowledge and expand their career potential beyond the undergraduate degree.

Admission Requirements

The usual requirement for admission into the PhD program is a research-based MSc degree with a minimum 'B' average and supportive letters of reference. It is also possible for a student to transfer from the MSc program without completing the requirements of the latter if the student has an excellent academic record and shows a strong aptitude for research which can be expanded to the doctoral level.

Applicants should submit a one page statement of research interests, background experience, and career goals to assist in the identification of a faculty advisor who has the facilities and funding necessary to support the thesis research. Students may be admitted into the fall, winter or spring semesters.

Degree Requirements

The major emphasis in the PhD program is research and the preparation of an acceptable thesis. There are no specific course requirements except for a seminar course which provides training in technical communications. It is usual however for most students, in consultation with their advisory committee, to select prescribed studies and additional courses in preparation for the qualifying examination and thesis research. The qualifying examination is in two parts, written and oral, and evaluates the student's knowledge in the fields of food chemistry, food microbiology and food processing/engineering. In addition, the advisory committee is required to submit a written evaluation of the student's performance to date in research and the student's potential as a researcher. The PhD program is completed by the submission and successful defense of an acceptable thesis.

Interdepartmental Program

Food Safety and Quality Assurance MSc Collaborative Program

The Department of Food Science participates in the MSc program in food safety and quality assurance. Professors Barbut, Dalgleish, Goff, Griffiths, Hill, Kakuda, Le Maguer, Lencki, Marangoni, Mine, Powell, Schraft, Subden, Swatland, Tung and Yada are members of the Food Safety and Quality Assurance Interdepartmental Group. These faculty members' research and teaching expertise includes aspects of food safety and quality assurance; they may serve as advisors for MSc students. Please consult the Food Safety and Quality Assurance listing for a detailed description of the MSc collaborative program.
