FAQs about Citrus

What are citrus fruit?

Citrus fruits are the most important fruit tree crop in the world and are grown in more than 140 countries. Citrus fruit grow on flowering trees and shrubs with evergreen leaves. The fruit of any citrus tree is actually a kind of modified berry with a tough, leathery rind, known as a hesperidium. The juices of citrus fruits are high in citric acid, which gives them their distinctive sharp and tangy flavour.

Unlike many other fruits, citrus are ‘non-climacteric’ fruits. This means that they cannot be ripened after picking. Citrus fruits have to be fully ripened on the tree before harvest. Citrus fruit that is grown in countries without a cool winter will stay green on the outside, as the fruit needs cold to turn yellow or orange. Fruit that is ripe inside but green on the outside can be picked and ‘degreened’ later in a cool place.
