This is precisely the main reason why wax may be used to extend shelf life, petroleum is hydrophobic (water repellent) which means that a petroleum-based wax coating will help prevent loss of water in food. This, in turn, will prevent the shrinkage of fruits and vegetables and extend their shelf life.

Explanation:

It is noticed that the "jam or jelly" is poured over by "melted paraffin wax". The purpose is to seal the container and keep it out from water and air. The wax is widely spread in order to keep the wax lighter and stays it on top.

This process helps in preventing the contamination by microorganism like bacteria, fungi, etc. since it is made of sugar syrup it is more likely to get attack by the microorganism.
