Why is Nigerian orange green?
In Nigeria, oranges retain a lot of the chlorophyll created because of the large amount of sunshine they receive. In temperate countries, oranges are often ‘cold-shocked’ to allow the orange color shine through. Or exposed to ethylene gas, which fragments the chlorophyll and releases the beta carotenes.
Where are oranges originally green?
