Description

L-Malic Acid is a naturally occurring dicarboxylic acid that serves as a key intermediate in the Krebs cycle and a versatile acidulant in industrial formulations. Its clean, smooth, and persistent sour taste profile makes it a superior alternative to citric acid in many applications, offering enhanced flavor synergy and improved microbial stability. This high-purity ingredient is essential for manufacturers in the food & beverage, pharmaceutical, and personal care industries seeking precise acidity control and natural labeling.

Application

  • Food & Beverage: Primary use as an acidulant and flavor enhancer in fruit-flavored drinks, candies, jams, and low-calorie products for a more natural taste profile.
  • Pharmaceuticals: Used as an active pharmaceutical ingredient (API) intermediate, an excipient in effervescent tablets, and a component in topical formulations for skin conditioning.
  • Personal Care & Cosmetics: Acts as an α-hydroxy acid (AHA) in skin care products for exfoliation and moisturization, and as a pH adjuster in shampoos and lotions.
  • Industrial Chemistry: Serves as a chiral building block for organic synthesis, a metal chelating agent, and a component in electroplating and cleaning solutions.
  • Animal Feed: Utilized as a feed additive to improve palatability and support digestive health in livestock.

Quality Control

Our L-Malic Acid is produced under a strict quality management system. It can be manufactured to meet various pharmacopeial standards including USP, EP, JP, and FCC for food grade applications. Every batch is supported by a comprehensive Certificate of Analysis (COA) verifying identity, purity, and safety parameters. We ensure full traceability and compliance with relevant global regulations such as REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after opening to prevent caking and degradation due to moisture absorption.
