Titratable acidity of fruit juices is an important parameter in determining fruit maturity and sour taste in citrus fruits.
The purpose of a pH indicator in the manufacturing of fruit juice is to monitor and control the acidity level of the juice. This helps to ensure that the juice is safe for consumption, as well as to maintain consistency in taste and quality. pH indicators are used to determine the endpoint of the juice processing to achieve the desired pH level for optimal flavor and shelf life.
The brix acid ratio in juice indicates the balance between sugar content (measured in brix) and acidity. A higher ratio typically suggests sweeter juice with lower acidity, while a lower ratio indicates a more tart juice with higher acidity. This ratio is important for determining the taste and overall quality of the juice.
Some fruit juices that are low in acidity include apple juice, pear juice, and watermelon juice. These fruits have a milder flavor profile and are generally easier on the stomach for those sensitive to acidic foods.
The acidity of orange juice can increase when stored at higher temperatures, as heat can cause the breakdown of certain compounds in the juice that contribute to its acidity.

Tomato juice is considered acidic, with a pH typically ranging from 4.0 to 4.6. This acidity is primarily due to the presence of organic acids, such as citric and malic acid. While it is not as acidic as some other fruit juices, it can still contribute to acidity in the diet.
Lemon juice is acidic, which lowers the pH of the fruit and creates an environment that is less hospitable to bacteria, mold, and enzymes that cause spoilage. This acidity helps slow down the oxidation process, which helps to preserve the fruit and maintain its freshness for a longer period of time.
