why does fruits become brown in colour when exposed to air?
Asked by vivek | 26th Feb, 2012, 11:25: AM
Apples alonwith some other fruits and potatoes have a specialized enzyme in them as well as an iron containing phenols. They react with oxygen. When an apple is cut open the enzyme and phenols become exposed and react with the oxygen in the atmosphere. It basically ends up forming a kind of rust on the surface.
