Malic Acid Extra Pure

Whatsapp Order

Malic Acid Extra Pure is a high-grade, naturally occurring dicarboxylic acid known for its sharp, tart flavor and versatility in both laboratory and industrial settings. It is commonly found in fruits such as apples and is widely used as an acidulant in food and beverage formulations, where it enhances flavor, preserves freshness, and improves pH stability. In laboratory applications, Malic Acid is employed in biochemical research, particularly in studies involving the citric acid cycle, due to its role as an intermediate metabolite. Its excellent solubility in water and mild acidity also make it suitable for cosmetic formulations and pharmaceutical preparations. The extra pure grade ensures high analytical accuracy and consistent quality across applications requiring strict purity standards.
