Lets Eat This
course is not currently being offered
This course will explore the science of food, both as a necessity and as a source of pleasure, through an understanding of the underlying science of food, nutrition, cooking, and sensation. All foods are chemicals and the body uses these chemicals in various ways. Cooking is a combination of chemical and physical processes, and the course will include some cooking exercises aimed at understanding the role of various ingredients in the final product obtained, whether muffins or mayonnaise. Food is also a source of sensory pleasure. The chemical basis of taste and smell will be considered including tasting exercises. Finally, there are safety, economic, political and social justice issues surrounding our use of food and its availability. Students will explore some of these issues through independent research and both written and oral presentations.
1 credit Enrollment limited to 24 students.
