DL‑Malic Acid – Premium Food-Grade Acidulant & Versatile Industrial Chemical

Product Overview

DL‑Malic acid (CAS: 6915‑15‑7 / 617‑48‑1, E296) is a racemic mixture of equal parts L‑malic acid and D‑malic acid. With the molecular formula C₄H₆O₅ and molecular weight of 134.09, it occurs naturally in fruits like apples and is industrially synthesized for consistent quality and cost‑effectiveness. It appears as a white, odorless crystalline powder or granules with a smooth, long‑lasting sour taste—20% stronger than citric acid, making it a preferred choice for flavor enhancement.

Core Advantages

• Superior Taste Profile: Smoother, more lingering sourness than citric acid, avoiding sharp or bitter aftertastes.
• High Solubility & Stability: Dissolves rapidly in water; stable under normal storage and processing conditions.
• Multi‑Functionality: Acts as an acidulant, flavor enhancer, pH regulator, preservative, and chelating agent.
• Cost‑Effective: Industrially synthesized via mature maleic anhydride hydration, ensuring stable supply and competitive pricing.
• Regulatory Compliance: Approved as a safe food additive (E296) globally, meeting JECFA and regional standards.

Applications

1. Food & Beverage Industry

• Beverages: Soft drinks, fruit juices, energy drinks, and sports drinks—enhances flavor, extends shelf life, and balances sweetness.
• Confectionery: Candies, gummies, jams, and jellies—provides a natural tartness and improves texture.
• Bakery & Dairy: Bread, cakes, ice cream, and yogurt—regulates pH, improves leavening, and stabilizes emulsions.
• Sauces & Seasonings: Ketchup, mayonnaise, and salad dressings—enhances umami and acts as a preservative.

2. Pharmaceutical Industry

• Used as an acidifier, buffering agent, and stabilizer in drug formulations.
• Improves solubility and absorption of active pharmaceutical ingredients (APIs).
• Applied in oral liquids, tablets, and effervescent powders for pH adjustment.

3. Cosmetics & Personal Care

• Acts as a pH adjuster and exfoliant in creams, lotions, and toothpaste.
• Chelates metal ions, preventing product degradation and discoloration.

4. Industrial & Agricultural

• Metal Cleaning: Removes rust and scale in metal processing.
• Electroplating: Adjusts pH and improves coating adhesion.
• Agriculture: Used as a feed additive for livestock to enhance digestion.

Production Method

Our DL‑malic acid is manufactured via the industrial mainstream maleic anhydride high‑pressure hydration process:

1. Raw materials: Maleic anhydride + water.
2. Reaction conditions: 185 ± 3 °C, 1.0 MPa, 6–8 hours in an autoclave.
3. Post‑processing: Cooling → vacuum concentration → crystallization → centrifugation → drying.
4. Quality control: Strict testing at every stage to ensure compliance with food‑grade standards.

Packaging & Storage

• Packaging: 25 kg net weight per fiber drum or kraft paper bag (customizable).
• Storage: Sealed, stored in a cool, dry place (2–30 °C), away from moisture and high temperature.
• Shelf Life: 24 months under proper storage conditions.
