What happens to vitamin C when exposed to air?
Oxygen and light react with vitamin C to degrade it and this is accelerated when there are high temperatures as well. It is a water soluble vitamin. When oxygen in the air reacts with vitamin C, oxidation occurs which is a chemical change that results in the breakdown of this vitamin.Click to see full answer….

Furthermore, what happens to vitamin C when exposed to light?It is sensitive to heat and light and it is destroyed over time when exposed to atmospheric oxygen (1-5). Vitamin C is sensitive to light (2,4). The presence of ascorbic acid delays the decomposition of vitamin B2 (9).Furthermore, what will happen to the vitamin C content in the fruit juices if they are exposed to air for a day? The problem is that when commercial orange juice is produced it goes through a process of pasteurization (it is heated). So much of the vitamin C that was in there is gone by the time it hits your glass. A similar process happens when we cut or peel our produce. If left exposed to air the nutrients begin to degrade. Secondly, how long does it take for vitamin C to oxidize? Vitamin C That Has Oxidized in the Bottle After contact with light, heat and air, vitamin C eventually oxidizes and loses its potency. You’ll know it when your serum changes colour, turning brown. (With L-ascorbic acid, this usually takes about three months after opening the bottle.)Does oxygen destroy vitamin C?Because the vitamin is an acid, it is reasonably stable in acidic solutions, but in neutral or basic solutions it is easily and rapidly oxidized by dissolved oxygen. Because vitamin C is so readily oxidized, it is easier to analyze vitamin C using an oxidation-reduction titration rather than an acid-base titration.
