When ready to ship frozen orange concentrate to a customer, such as a juice packager, the concentrate is blended from the various tanks to meet the specifications of the customer and meet USDA requirements. Essences and oils (recovered in the processing process) are also added back to enhance the flavor. This blending process is how juice made from concentrate, FCOJ, has a more consistent quality year round than fresh juice or NFC. The FCOJ (at about 65° brix) is either put into 55-gallon drums and shipped in a refrigerated truck, or is loaded onto a special food-grade insulated tanker truck and delivered to a packaging plant. (Some Florida processing plants also have packaging plants at the same site. Many dairies around the country also package orange juice using the same equipment used to package milk). To make cans of frozen concentrate, filtered water is added back to bring the brix level down to 42° (about 3 times more concentrated than fresh juice). For chilled reconstituted (recon) ready-to-serve (RTS) orange juice, filtered water is added to bring the brix down to about 11.8°, the average of fresh squeezed juice. It is then put up into cardboard cartons, glass, or plastic jugs to be sold at the retail store. All FCOJ, Recon, and NFC forms of orange juice are always pasteurized before it reaches the consumer to protect from contamination.
