Gellan gum films as carriers of l-(+)-ascorbic acid

Edible gellan films were evaluated as carriers for stabilizing l-(+)-ascorbic acid (AA) for nutritional purposes and antioxidant effect on foods. AA retention during film casting (initial value), as well as stability and non-enzymic browning (NEB) development along film storage (25 °C) at 33.3%, 54....
