De-greening is an international practice in the process of removing the green colouring ( known as chlorophyll ) from the skin of citrus fruit . This is achieved by introducing measured amounts of ethylene gas into a temperature and humidity-controlled environment . It is important to note that only mature fruit is suitable for de-greening .
It is absolutely critical that immature fruit is not harvested and de-greened . Immature fruit will have very high acid levels and low sugar levels and will generally not meet minimum standards , but immature dark green fruit will also not successfully de-green .
