The parts of a citrus fruit
Know the anatomy of citrus fruits, what they are and the description of their main parts.

Everyone knows an orange and its anatomy: rind and segments. But its anatomy is a bit more complex. In this post, we are going to explain its different parts.

The main parts of an orange are:

Exocarp or flavedo: it is the peel or rind, but only the orange bit. The exocarp or flavedo is formed by an epidermis and hypodermis that is green when it is not yet ripe and orange when it is already ripe. This part is composed of small vesicles containing essential oils that are mainly used to make perfumes and flavorings.

Mesocarp or Albeldo: This part is also part of the orange peel. Its appearance is spongy and white in color. It is the one that contains more pectins and it is used mainly for the realization of jams although it is also rich in glycosides.

Endocarp or pulp: It is the part that we eat of the orange and of the rest of citrus fruits and supposes the greater percentage of its weight. It is formed by segments or juice sacs and seeds. This is where the different organic acids (such as vitamin C), sugars and water that provide this fruit are found. Inside the endocarp or pulp we can find the following parts:

Septa or membranes: these are the walls that separate the segments. 

Seeds: they are the seed of the tree.

Central axis: it is the central part of the orange. As well as the mesocarp or albeldo its aspect is also spongy and white in color.
