Introduction
Citrus aurantium, also known as Bitter Orange or Seville Orange, orange—refers to the citrus tree Citrus sinensis and its fruit. The orange is a hybrid of ancient cultivated origin, possibly between pomelo (Citrus maxima) and tangerine (Citrus reticulata). It is a small tree, growing to about 10 m tall, with thorny shoots and evergreen leaves 4-10 cm long. Oranges originated in southeast Asia, in either India or modern day Pakistan, Vietnam or southern China. The fruit of Citrus sinensis is called sweet orangeto distinguish it from Citrus aurantium, the bitter orange.
Oranges are widely grown in warm climates worldwide, and the flavors of orange vary from sweet to sour.
The fruit is commonly peeled and eaten fresh, or squeezed for its juice. It has a thick bitter rind that is usually discarded, but can be processed into animal feed by removing water using pressure and heat. It is also used in certain recipes as flavoring or a garnish. The outer-most layer of the rind is grated or thinly veneered with a tool called a zester, to produce orange zest, popular in cooking because it has a flavor similar to the fleshy inner part of the orange. The white part of the rind, called the pericarp or pith, is a source of pectin.
