What is the acidic level of orange juice?

Orange juice has a pH level of around 3.5, making it acidic. The acidity of orange juice comes from the citric acid content, which is a natural component of citrus fruits. Citric acid gives orange juice its characteristic tart flavor and is also responsible for its preservative properties. However, the acidity of orange juice can also cause stomach discomfort in some individuals, such as those with gastroesophageal reflux disease (GERD). To reduce the acidity of orange juice, it can be diluted with water or mixed with an alkaline food or drink, such as milk or baking soda.
