Cooking Chemistry: Flavors and Reactions

Dr. Kiki Sanford explains the science behind cooking processes like caramelization and the Maillard reaction. These non-enzymatic browning reactions enhance flavors and aromas in foods such as steak, coffee beans, caramel, and toast. Caramelization involves sugar interactions, while the Maillard reaction involves sugars and amino acids. The video details how these reactions occur, their chemical processes, and their impact on food flavor and aroma. It emphasizes the scientific principles behind cooking, making it clear that cooking is not just an art but also a science.

What is the common factor among steak, coffee beans, caramel, and toast when cooked?
