In Europe, oranges are harvested from August (early varieties from Seville) to May (late variety from Tardivo di Sanvito, Sardinia). The most prominent orange-based product in global trade is orange juice, which mostly comes from Brazil and is traded in the form of concentrate (syrup). Fresh oranges have also become firmly established in the food industry in numerous countries. Oranges are often sold in an orange wrapper, a practice which used to be carried out for protective purposes but is now used as an advertising tool.
