- Beginning around 1917, a company began packaging orange juice to sell.
- The process of orange juice concentrate was patented in 1948.
- It was originally developed for the World War II troops as it was a reliable source of vitamin C.
- The concentrate is made by heating the fruit in a vacuum and evaporating the water, the thick substance that remains is the concentrate.
- Concentration methods have been used to optimize its transportation across the world, to then be re-constituted with the same volume of water that was evaporated from it, once it reaches the location of juice manufacture.
- Juice from concentrate is popular because the concentrate is easier and cheaper to store than liquid juice.
- Contrary to popular belief, fruit from concentrate is real fruit juice.
- The negative of this manufacturing process is that vitamins and minerals might be lost in the water that is filtered out.
- What is the difference between the production of pure juice and juice from concentrate? With concentrate they remove the water, fruit pulp and flavors, which are added again in a later production step after transport and pure juice is simply the juice of the orange.
- A 4-ounce glass of orange juice prepared from concentrate provides 280% of the Daily Value of vitamin C. This nutrient plays an important role in immunity and wound healing.
