Food acids are essential components used in the food industry for flavor enhancement, preservation, and cooking. However, there are instances where you might want to refer to these acids using different names. Some of the synonyms for the term "food acid" include flavoring acids, souring agents, acidulants, organic acids, or simply acids. Each of these terms describes compounds that add the tang, tartness, or tanginess to food and drinks. Examples of popular flavoring acids include citric acid, acetic acid, lactic acid, and malic acid. Acidulants, on the other hand, denote food acids that control the pH levels of products to inhibit spoilage and microbial growth.
