Stability of L-(+)-ascorbic acid in alginate edible films loaded with citric acid for antioxidant food preservation

Alginate of known copolymer composition was applied to antioxidant film developed by loading L-(+)-ascorbic (AA) and citric (CA) acids. Relative humidity (RH, 33.3-75.2%) of storage (25.0 °C) and glycerol (plasticizer) level, separately and through their interaction, decreased the AA hydrolytic stab...

However, CA slowed down the browning development at longer storage times because of the changes in the kinetic order. It may catalyze the formation of unstable color compounds. The present work permitted to determine that AA and CA were 100% recovered after film casting. Also, it allowed finding the adequate film composition and period where the alginate film supporting AA and CA can be used as an antioxidant active interface for food preservation. © 2015 Published by Elsevier Ltd.
