Citrus aurantium L.
Bitter orange is a bitter tasting orange used to produce marmalade/
It’s also known as Seville Orange, Sour Orange, Marmalade Orange or Bigarade Orange.
Bitter orange is grown throughout the mediterranean region. There are many varieties but the best known is the seville orange, used in the production of marmalade. Seville oranges are commercially grown in Seville, Spain and are shipped to Britain for marmalade production.
Characteristics of seville orange
The seville orange is particularly sour, tart and bitter in flavour and is laden with seeds. It has a thick, dimpled and rough skin, which is deep orange in colour, and clings tightly to the fruit. The skin contains essential oils. It’s comparatively higher in pectin, compared to sweet orange and is therefore very suitable for production of orange marmalade.
Use of seville orange
The fruit is rarely consumed but mainly used in production of marmalade. It can also be used for production of orange flavoured liqueurs.
The bitter orange is also used as a rootstock in groves of sweet orange.
Essential oil extracted from the peel can also be used in the perfume industry, or as a flavouring agent.
