Why does lemon juice slow down the process of oxidation?
Oxidation is cause by (obviously) the oxygen in the air. When you cut up fruit for instance, the parts without skin which are exposed will turn brown quickly. Squeezing lemon juice over your fruit (apple, pear, banana, ect) will stop oxidation because the juice contains Vitamin C (ascorbic acid). The ascorbic acid reacts with the oxygen preventing the browning on the apple (fruit). In theory, other citric fruits would do the same thing. Whenever making an apple pie (or pear whatever) squeeze a lemon over the pieces as you cut them up (and toss) this will stop the oxidation process while you are cutting up all the fruit.
