Why is orange juice acidic?

Oranges and other citrus fruits contain citric acid, a weak organic acid that gives them their sour taste. Citric acid is also found in lemons, limes, grapefruits, and other citrus fruits. When these fruits are juiced, the citric acid is extracted along with the water and other nutrients. This results in orange juice that is acidic, with a pH typically between 3.0 and 4.0.

The acidity of orange juice has several benefits. First, it helps to preserve the juice by preventing the growth of bacteria and other microorganisms. Second, the acidity helps to dissolve minerals and nutrients from the orange peel, which are then released into the juice. This makes orange juice a good source of vitamin C, potassium, and other essential nutrients.

However, the acidity of orange juice can also cause some problems. For example, it can irritate the stomach and cause heartburn in some people. Additionally, the acidity can damage tooth enamel if orange juice is consumed in large amounts. To reduce the acidity of orange juice, it can be diluted with water or mixed with a less acidic liquid, such as milk or yogurt.
