Citrus fruit peel is not just a protective skin, it is an essential part of these succulent fruits. Citrus fruit peel varies from species to species: oranges, for example, can have a thicker and coarser peel whereas in the case of some species of lemons it is thinner and smoother.

Anthocyanins, natural pigments contained in fruit and especially in citrus fruits, give citrus peels their warm colours. Citrus peel is used to add flavour to foods and drinks.
