Orange juice is a popular beverage made from the extraction (squeezing) of liquid from fresh oranges. The term ``orange juice`` is also used, both colloquially and commercially, to refer to ``concentrated orange juice``.
Some refrigerated fresh juice is sold to consumers. In the U.S., Canada and the U.K. it is labeled ``not from concentrate``. In the USA all commercial orange juice is pasteurized. ``Freshly squeezed`` juice is unpasteurised and has a shorter life than pasteurized juice, but is considered better quality. Refrigerated juice shipped in liquid form is traded between producers as direct juice.
Not from concentrate orange juice is typically more expensive, ranging from two to eight times the price of concentrate.//
Orange juice is a source of vitamin C (ascorbic acid), potassium, thiamine, Phosphorus G, folic acid (Vitamin B9) and vitamin B6. One 8-ounce glass of 100 percent orange juice counts as almost 25 percent of the USDA-recommended daily fruit and vegetable servings, based on a 2,000-calorie diet. Research shows orange juice is more nutrient dense than many commonly consumed 100 percent fruit juices, such as apple, grape, pineapple and prune.
Citrus juices also contain flavonoids that are believed to have beneficial health effects. If drunk on an empty stomach, orange juice can exacerbate present gastrointestinal conditions and/or cause mild and temporary stomach upset. Due to the citric acid, orange juice typically has a pH of 3.5. Drinking or sipping orange juice can therefore cause erosion of the tooth enamel, otherwise known as 'acid erosion'. Some publications recommend using a straw when drinking orange juice so that the juice does not come into contact with the teeth.
Freshly squeezed juice and filtered orange juice is pasteurized and is evaporated under vacuum and heat to remove most of the water before it is frozen. This process strips out certain essences and oils. The concentrated juice, about 65Â°Bx, is then stored at about +10Â°F (-12Â°C). At this point essences and oils, recovered during the vacuum concentration process, are added back to restore the flavor. To make cans of frozen concentrate for sale, filtered water is added back to bring the Brix level down to 42Â°Bx, about three times the concentration of fresh juice.
When water is added to freshly-thawed concentrated orange juice, it is reconstituted. Most of the orange juice sold today throughout the world is reconstituted juice. There is a huge difference in the volume of frozen concentrated orange juice and unprocessed juice and this makes a difference in the price the consumer is charged.
Orange juice containing pulp seems to be more nutritious than no-pulp varieties due to the flavonoids contained in the pulp.
The Intercontinental Exchange trades FCOJ futures and options on futures. Several exchanges, including the Brazilian Mercantile and Futures Exchange, the New York Mercantile Exchange, and the Chicago Mercantile Exchange, have tried to co-list these contracts and steal the volume away from the ICE. However, to this date none have succeeded and their products have been wound down.
A small fraction of fresh orange juice is canned. Canned orange juice does retain Vitamin C much better than bottled juice. However, the canned product loses flavor when stored at room temperature for over 12 weeks.
