Detailed study of the chemical, biochemical and physical characteristics of food components. Their measurement, and the interactions between components, are used to describe the compositional changes that occur in foods from harvest to consumption.
The course is designed for students to develop an understanding of the physicochemical properties of the major food components and their importance in food. The properties of water, proteins, fats, carbohydrates, colours, vitamins and minerals are covered in detail and provide a foundation for future studies in food science. The principles of major food processing operations and how foods are made safe for consumption over extended time periods are evaluated. In the practical sessions, students will learn the proximate analyses of food components.

- Schedule C
- For students not taking Consumer Food Science or Food Science as a major or minor subject, the prerequisite is (FOSC 111 or CHEM 191) and 36 further 100-level points.
- Teaching staff
- Paper Structure
The main themes covered are:
- Natural food components and their properties and measurement
- Food component stability and interactions
- Introductory food processing and preservation
The final examination is three hours in duration and is worth 60% of the final mark. 10% can be replaced by an optional Terms Test (on a plussage basis). The other 40% is evaluated during laboratory performance with a mixture of laboratory reports (3 reports, each worth 10%) and questions (2 sets of questions, each worth 5%).
- Teaching Arrangements
Food Science 201 has three lectures per week and six Laboratory classes over thirteen weeks.
Students should allocate 12 hours per week to this course over the semester. This time includes lectures, laboratories, completion of reports and independent study.

- Learning Outcomes
Students who successfully complete this paper will
- Be introduced to the proximate composition of foods, interaction between components and processing techniques used in the food industry
- Understand the matter that makes up our food and provides the key to preservation
- Predict behaviour so that food can have a useful life over very long periods from harvest to consumption
- Relate the theory of fluid flow, heat transfer and mass transfer to understanding of unit operations in food processing and in the design of food processing equipment
- Appreciate the effects of process equipment choice on the quality and safety aspects of the food being processed and to economically choose the most appropriate unit operation for the desired process outcome
