Chemical Structure
Basic Info
DL-Malic Acid (CAS Number: 617-48-1) is a organic dicarboxylic acid widely utilized as a sour agent, flavor enhancer, and pH regulator across the global food, beverage, personal care, and industrial chemical sectors. Commercially produced through synthesized biological or chemical routes, this white crystalline powder consists of an equal (racemic) mixture of D- and L-malic acid isomers.
Compared to traditional acidulants like citric acid, DL-Malic Acid delivers a smoother, longer-lasting tartness that closely mimics the natural acidity found in green apples and unripe fruits. Its low melting point, high water solubility, and excellent thermal stability make it a preferred ingredient for modern food formulators seeking to round out harsh flavors, mask artificial sweetener aftertastes, and maintain consistent pH profiles in heat-processed products.

A. Food & Beverage Formulation
Flavor Profile Enhancement: Provides a sustained sourness that lingers smoothly, masking the bitter aftertaste of high-intensity artificial sweeteners (e.g., aspartame, sucralose) in low-calorie beverages.
Confectionery & Hard Candies: Excellent heat stability prevents browning or inversion during candy boiling processes, providing a crisp, fruit-like acidity in hard candies, gummies, and jellies.
Fruit & Vegetable Processing: Acts as a natural color retainer and pH stabilizer in jams, jellies, canned fruits, and fruit juices.
B. Personal Care & Cosmetics
pH Adjustment: Used as a safe buffering agent in skincare lotions, shampoos, and facial cleansers to match natural skin pH levels.
Exfoliating Formulations: Functions as an Alpha Hydroxy Acid (AHA) component in mild cosmetic formulations to support skin surface renewal.
C. Industrial & Chemical Synthesis
Metal Cleaning & Electroplating: Functions as a chelating agent to dissolve mineral deposits and clean metal surfaces without causing severe corrosion.
Polymers & Resins: Serves as a building block or intermediate in the synthesi
FAQ
A1: While citric acid provides a rapid, sharp burst of acidity that fades quickly, DL-Malic Acid delivers a smoother, more prolonged sour profile. Additionally, malic acid exhibits higher solubility in certain systems and offers superior taste-masking capabilities for artificial sweeteners.
A3: DL-Malic Acid should be stored in its original sealed packaging in a cool, dry, well-ventilated warehouse away from direct moisture, heat, and direct sunlight. When kept under proper conditions, the product maintains a stable shelf life of 24 months from the date of manufacture.
A4: Yes. Because DL-Malic Acid contains no sodium and works synergistically with low-calorie sweetening systems, it is widely utilized in dietary, low-calorie, and sugar-free beverage powders.
A5: You can request evaluation samples (typically 100g–500g), complete Certificates of Analysis (COA), and SDS documents by filling out the contact form on our website or directly contacting our technical sales representatives via email.
