Knowra Food chemistry Food chemistry Food chemistry studies the composition, properties, reactions, and transformations of food and its ingredients, from processing and storage to cooking and digestion.
Maillard reaction : A set of reactions between reducing sugars and amino compounds that produces brown pigments and many roasted or savory aromas. It creates characteristic colors and flavors in heated foods such as bread crust and roasted coffee.
Water activity : A measure of how available water is for microbial growth and chemical reactions in a material. It helps explain why foods with similar moisture content can differ in stability.
Food preservation : Methods that slow spoilage and maintain food quality or safety during storage. Chemical stability is central to choosing preservation conditions and predicting shelf life.
Mayonnaise : A thick sauce formed by oil droplets dispersed in an aqueous mixture containing egg yolk or another emulsifier. Its stability illustrates how emulsifiers and droplet structure shape a food.
Caramelization : The heat-driven decomposition of sugars that produces brown pigments and complex flavors. It explains sugar browning without the amino compounds required for the Maillard reaction.
pH : A logarithmic measure of hydrogen-ion activity in a solution, commonly used to describe acidity. Food acidity influences flavor, protein behavior, preservation, and reaction rates.
Food fortification : The deliberate addition of vitamins or minerals to foods to improve their nutritional content. Ingredient chemistry determines whether added nutrients remain stable and bioavailable.
Bread : A baked food commonly made from flour, water, and a leavening agent. Dough development, fermentation, and baking bring several food-chemistry processes together.
Lipid oxidation : Chemical reactions in which oxygen alters lipids, often producing rancid odors and flavors. It is a major cause of flavor deterioration in foods rich in fats.
Protein : A biological macromolecule made of amino acids, with structures and functions determined by their sequence and folding. Proteins provide food structure and supply amino groups for browning reactions.
