Polymeric Indicators and Biosensors in Food

Chapter 5 describes the use of polymeric food additives such as colorants, antioxidants, nonnutritive sweeteners, nonnutritive hydrocolloids, animal feed additives, as well as indicators and biosensors in foods. Polymeric food additives are to enhance food quality, to preserve and enhance food flavor, taste, and appearance without affecting food nutritional value. They are substances other than basic foodstuffs, which exhibit their functions prior to consumption of the food products, either acting as aids in the manufacture, preservation, coloration, and stabilization of food products, or serving to improve the biological value of certain foods.
