Food chemistry is a branch of science that explores the composition, properties, and interactions of substances found in food. It focuses on understanding the chemical processes that occur during food production, processing, and storage. Food chemists study the structure and function of molecules such as proteins, carbohydrates, lipids, vitamins, minerals, and other bioactive compounds present in various food sources.

One aspect of food chemistry is analyzing the chemical changes that occur during cooking and processing. This includes understanding the Maillard reaction, which gives cooked food its characteristic flavors and aromas, as well as the denaturation of proteins and the caramelization of sugars. Food chemists also investigate the effects of different processing methods, such as heating, freezing, and fermentation, on the nutritional content and quality of food.

Food chemistry also delves into food additives and preservatives. Chemists evaluate the safety and effectiveness of these substances, ensuring they do not pose health risks and contribute to the overall quality, taste, and shelf life of food products. Additionally, food chemists play a crucial role in analyzing contaminants and toxins in food, working to develop methods to detect and mitigate their presence.
