Description
What is L‑Malic Acid?
L‑Malic Acid Powder is a naturally‑occurring organic acid, appearing as white crystals or crystalline powder. Naturally found in fruits such as apples and grapes, it is also a key intermediate in the human body’s energy metabolism (TCA cycle), so it can be easily absorbed and utilized by the human body.
• Mild acidulant: It delivers a soft, long‑lasting sour taste similar to natural fruit. Its sour intensity is about 20‑25% higher than citric acid, yet with a milder taste and no oral irritation. In food and beverages, it effectively enhances flavor, masks bitter notes, and acts as a pH regulator and antioxidant auxiliary agent.
• Involvement in energy metabolism: It directly participates in the tricarboxylic acid (TCA) cycle in the human body and supports energy (ATP) production. It has therefore been studied for potential exercise‑performance‑improving effects.
• Biological activities: Studies indicate its potential antioxidant and anti‑inflammatory properties.
• Food & beverage industry: Widely used as an acidity regulator and flavor enhancer in fruit juices, carbonated drinks, jellies, confectionery, jams, mayonnaise and other products. It is also commonly applied in low‑salt foods and health beverages.
• Pharmaceutical & health‑supplement industry: Used in compound amino‑acid injection formulations to improve amino‑acid utilization; also used as a component in electrolyte solutions for patients requiring fluid‑replenishment therapy. Its derivatives (such as potassium and sodium salts) have been researched for liver‑function disorders and hypertension‑related applications.
• Other industrial fields: Also applied in daily‑chemical products, e.g., in toothpaste formulations.
