The course focuses on a deep understanding of the chemical processes involved in food production, storage, and culinary treatment. Desirable and undesirable changes as well as key reactions in food technologies are taught. Students will learn about methods of removing process contaminants, current legislation, their dietary intake, and ways to suppress undesirable processes. Chemical reactions of macronutrients and minor species do not occur separately; emphasis will be placed on the interaction between the products of chemical reactions with input compounds (autooxidation, Maillard reaction etc.). Emphasis will be placed on modern application of enzymatic reactions in food process chemistry.
