What is the "white powder" on my fruit?

Updated by SFA
The white powder is a natural surface wax found in a variety of fruits that acts as a protection against moisture loss, pests, and certain diseases. Depending on the compounds found in the bloom wax of each fruit species, they may appear white and be commonly mistaken as mould. To differentiate surface wax from mould, you can check for their appearance. Bloom wax appears as a dry, whitish or bluish grey powder that coats the surface of fruits uniformly. In contrast, mould typically has a fuzzy or slimy texture and appears as irregularly shaped patches on the fruit.
