The pH level of food influences its flavor, texture, and shelf life. [33] Acidic foods, such as citrus fruits, tomatoes, and vinegar, typically have a pH below 4.6 [34] with sharp and tangy taste, while basic foods tastes bitter or soapy. [35] Maintaining the appropriate pH in foods is essential for preventing the growth of harmful ...
Human blood is maintained between pH 7.35 and 7.45 by acid–base homeostasis mechanisms. Levels above 7.45 are referred to as alkalosis and levels below 7.35 as acidosis. Both are potentially serious.
Anthocyanins may be used as pH indicators because their color changes with pH; they are red or pink in acidic solutions (pH < 7), purple in neutral solutions (pH ≈ 7), greenish-yellow in alkaline solutions (pH > 7), and colorless in very alkaline solutions, where the pigment is completely reduced.

The lowest pH of the secreted acid is 0.8, [5] but the acid is diluted in the stomach lumen to a pH of between 1 and 3. There is a small continuous basal secretion of gastric acid between meals of usually less than 10 mEq/hour. [6] There are three phases in the secretion of gastric acid which increase the secretion rate in order to digest a ...
Citric acid sold in a dry powdered form is commonly sold in markets and groceries as "sour salt", due to its physical resemblance to table salt. It has use in culinary applications, as an alternative to vinegar or lemon juice, where a pure acid is needed. Citric acid can be used in food coloring to balance the pH level of a normally basic dye.
A caustic basic solution is produced, called lye water. Then, the lye water would either be used as such, as for curing olives before brining them, or be evaporated of water to produce crystalline lye. [1] [2] Today, lye is commercially manufactured using a membrane cell chloralkali process.

Acidity regulators, or pH control agents, are food additives used to change or maintain pH (acidity or basicity). [1] They can be organic or mineral acids, bases, neutralizing agents, or buffering agents. Typical agents include the following acids and their sodium salts: sorbic acid, acetic acid, benzoic acid, and propionic acid. [2]
