Fruit juice from concentrate is obtained in the same way except that the juice is concentrated through evaporation of natural water content. The juice is then restored by adding the same amount of water as was extracted from that juice during the concentration process.
One of the favorite fruit juices to have in substitute of a soda is orange juice. It tastes good, it is natural, and is readily available.
Orange juice contains substantial amounts of several micronutrients such as vitamin C, folate and polyphenols (e.g., hesperidin which is a flavanone), and may therefore contribute significantly to their daily intakes. Orange juice also is an excellent source B vitamin, potassium, phosphorous, and other elements.
Orange juice provides a good dose of vitamin C. Most persons can achieve 100% of the RDA for vitamin C by consuming moderate amounts of citrus fruit. Studies in humans have also provided strong evidence for the antioxidant properties of citrus. Drinking 500 mL/day of orange juice for two weeks (~250 mg ascorbic acid/day) increased plasma vitamin C concentrations by 40%–64% and reduced oxidative markers (8-epi-PGF2α) in adults, with a more pronounced effect in smokers.
Orange juice is a rich resource of flavonoids with many physiological properties involved in controlling antiviral activity and anti-microbial activity. They are present in the form of the glycoside or aglycone, especially in citrus juices as glycosyl derivatives (flavonoid glycosides, FGs) which showed potential health benefits for the human body.
An 8-ounce glass contains as much potassium as a banana. It has a remarkable variety of phytonutrients. Other micronutrients available in orange juice including folate and polyphenols (e.g., hesperidin which is a flavanone). Studies show that hesperidin exhibits anti-inflammatory characteristics, and can impact positively on human microvascular function (elasticity and tone of blood vessels).
