ascorbic acid oxygen scavenger

Ascorbic acid is an effective oxygen scavenger.
It has antioxidant properties. Chemically, ascorbic acid (C₆H₈O₆) can react with oxygen. In this reaction, ascorbic acid is oxidized to dehydroascorbic acid. This process consumes oxygen and helps to reduce the oxygen content in its surroundings.
It's often used in food and beverage applications. In fruit juices, for example, ascorbic acid not only acts as a nutrient but also scavenges oxygen to prevent the oxidation of flavor - and color - sensitive components like polyphenols. This helps maintain the freshness and quality of the product by inhibiting spoilage reactions that are driven by oxygen. In the preservation of dried fruits, ascorbic acid can slow down the oxidative rancidity process and browning reactions that are caused by the reaction of the fruit's components with oxygen.
