All sorts of citruses

Yuzu, bergamot, lemon, mandarin, orange… Known for their freshness, citrus fruit pulp is found in both food and beauty product recipes. Citrus essential oils have several things in common but also particularities of their own. For example, grapefruit essential oil has a more effective action on the digestive system, whereas mandarin essential oil will be more suitable for the nervous system. Although all of them are more or less cleansing and purifying, what are their specific virtues?

 

What are citrus essential oils?

 

Essential oils and essences and/or citrus expressions have very different modes of extraction:

  • The essences come from citrus and are obtained by a process of cold expression consisting of mechanically breaking the zest pockets of these citruses. In most cases, the zest that will be used, either through cold pression, or by a system of “grating” rollers that allow to collect the essence.
  • Essential oils however are extracted from different parts of the plant and/or flower and are obtained by water vapour distillation.

Zest! When we talk about them, we say “essential oils” but in truth we should say “citrus essence”.

Added info

According to a report about world trade, the production of citruses has almost doubled in the last decades. The annual world production would be of almost 103 million tons  (source www.leconomist.com).

 

What fruit?

 Citrus essential oils are made from lemon, lime or bergamot for example. One hundred kilos of fruit is needed to produce about four kilos of lemon essence or one kilo of orange or mandarin essence.

What they have in common:

All citrus fruit is made of one:

– rind (pericarp)

– superficial rough and resistant layer that can be either yellow or orange (zest). The colour of this superficial layer is due to its content of flavonoids.

– internal, white and spongy layer

– juicy pulp containing pips and rich in vitamin C

The chemical composition of citruses is, among others:

  • Terpenes (about 90%)
  • Vitamin C
  • Flavonoids: very effective for venous tonus and lymphatic drainage. They help reducing inflammation and preserve good circulation while helping the healing of ulcers on legs.
  • Limonenes: molecules well known for the allergenic effect
  • Furo-coumarines make citrus fruit photo sensitive.

 

Citrus essences are very volatile and their use by date is shorter than for other essential oils (about 2 years). It is advised to keep them away from heat.

Added info

Citrus essences are particularly recommended for children. They have a soothing perfume and have very few counter-indications. They also are very affordable.
