Description

Malic Acid is a naturally occurring dicarboxylic acid widely recognized for its pleasant, tart taste and versatile functional properties. This high-quality ingredient is essential for formulators seeking to enhance flavor profiles, adjust acidity, and improve product stability. It serves as a critical component for manufacturers in the food & beverage, pharmaceutical, and personal care industries, where consistent purity and reliable supply are paramount.

Application

• Food & Beverage Industry: As an acidulant and flavor enhancer in sour candies, fruit-flavored drinks, jams, and low-calorie products to provide a smooth, lingering tartness.
• Pharmaceuticals: Used as an active ingredient in effervescent tablets and lozenges, and as an excipient to mask bitter tastes or stabilize formulations.
• Personal Care & Cosmetics: Incorporated into skincare products for its α-hydroxy acid (AHA) properties, aiding in exfoliation and skin renewal.
• Industrial Applications: Acts as a metal chelating agent in cleaning formulations and as a intermediate in chemical synthesis.
• Animal Feed: Utilized as a feed acidifier to support gut health and nutrient absorption in livestock.
