Orange (fruit) orange juice between the São Paulo and mid-south Florida areas makes up roughly 85% of the world market. Brazil exports 99% of its production, while 90% of Florida's production is consumed in the United States. Orange juice is traded internationally in the form of frozen, concentrated orange juice to reduce the volume used so that storage and transportation costs are lower. Oranges, whose flavor may vary from sweet to sour, are commonly peeled and eaten fresh or squeezed for juice. The thick bitter rind is usually discarded, but can be processed into animal feed by desiccation, using pressure and heat.
Orange juice Juice, 0.03% of recoverable oil is permitted. Deoiling through the use of vacuum distillation is the mechanism used to regulate the amount of peel oil in the juice. Condensation separates the oil and the aqueous distillate, which is returned to the juice. The next step is one of the most vital in the processing of orange juice. Pasteurization is important in destroying naturally occurring enzymes that are associated with deterioration of the juice. Pectinesterase is infamous for its deteriorative activity in orange juice. In the pasteurization process, the juice is generally rapidly heated to 197 °F for about 40 seconds.
