The word “wax” conjures up images of a white solid fat, such as candle wax or beeswax, but this is not the precise definition of wax. Wax is a fat-like substance that contains a variety of chemicals with high melting temperatures. Wax is highly hydrophobic; it is employed as a natural barrier to water and moisture, as well as microbes. Wax is also used as a coating over leaves and fruits for giving a glossy texture and longer shelf life.
