Malate salts are chemical compounds formed from malic acid, which is a naturally occurring organic acid found in many fruits, especially in apples. These salts are created when malic acid reacts with a base, resulting in a stable compound that can be used in various applications, including food and pharmaceuticals. In the food industry, malate salts are often used as flavor enhancers or preservatives due to their ability to improve taste and extend shelf life. Additionally, they can play a role in biochemistry, as they are involved in the Krebs cycle, a crucial process for energy production in living organisms.
