Antioxidants are used in a wide variety of food products, and their activity may vary depending on the temperature, food composition, food structure and availability of oxygen. Temperatures at which antioxidant activity may be required range from 180–200°C for frying oils, to about 5 °C for products such as margarine or mayonnaise that are stored in the fridge. Besides the processing and storag...
