What is the epicarp of an orange?

The epicarp is the outermost layer of the fruit, also known as the rind or peel. In oranges, the epicarp is composed of a thin, protective layer of cells covered by a waxy cuticle. The epicarp provides structural support and protection for the inner parts of the fruit, such as the pulp and seeds, and it also contains essential oils that contribute to the characteristic aroma and flavour of oranges. The colour of the epicarp varies depending on the orange variety, ranging from green to various shades of orange.
