citrus fruits



  • Fruits of the genus citrus which have been cultivated for 2000 years and known in Europe since the 16th century. They all have a two-layered separable green, yellow or orange skin, the outer layer (zest) being rich in essential oils, the inner (pith or albedo) being white and soft, all enclosing a segmented fruit containing juice sacs and seeds (pips). The juices contain sugar, flavours, aromas and citric acid. The relative proportions of these determine the palatability and uses of the fruit.
