Citric Acid CAS 77-92-9

Citric Acid is the most widely used organic acid and pH-control agent in the food and beverage industry. It provides a sharp, clean, tart taste that enhances flavors in soft drinks and candies.

Why choose our Anhydrous Citric Acid?

1. Pure & Dry: Since it lacks water molecules in its crystal structure, it has a higher active acid content by weight compared to the Monohydrate form.
2. Anti-Caking: It performs better in dry powder mixes (like seasoning blends or instant drink powders) because it is less prone to absorbing moisture and clumping under standard storage conditions.
3. Corn Fermentation: Produced from natural corn starch, making it suitable for vegetarian, Halal, and Kosher dietary requirements.
4. Solubility: It dissolves rapidly in water, releasing protons to lower pH effectively.

Physicochemical Properties

The table below represents the standard specification for Export Grade Anhydrous Citric Acid (BP/USP).

Applications

1. Beverages (Carbonated Drinks):
   • Used extensively in colas, sodas, and energy drinks to provide the characteristic “sour” kick and buffer the pH to prevent spoilage.
2. Confectionery & Food:
   • The white coating on sour gummies is often coarse Citric Acid. It also prevents sugar crystallization in jams and jellies.
3. Cleaning & Detergents:
   • A powerful chelating agent and builder. It replaces phosphates in eco-friendly dishwasher tablets and laundry detergents to tackle hard water.
4. Industrial Scaling:
   • Used to remove limescale from boilers and evaporators without corroding the metal equipment.
5. Construction:
   • Sometimes used as a retarder in concrete and gypsum to slow down the setting time.

Storage Conditions

• Environment: Store in a cool, dry, and well-ventilated place.
• Humidity Control: Although Anhydrous is more stable than Monohydrate, relative humidity (RH) should be kept below 50%. If the humidity is too high, the surface of the crystals can absorb moisture and eventually form hard lumps.
• Palletizing: Use wooden or plastic pallets. Do not place bags directly on the concrete floor to avoid moisture transfer.
• Shelf Life: 3 years if the bag remains sealed.

Safety Precautions

• Eye Irritation: Citric Acid is a strong eye irritant. If dust enters the eyes, it causes immediate stinging. Rinse with plenty of water for 15 minutes.
• Skin Contact: Generally safe, but prolonged contact with concentrated solutions can cause irritation. Wash with soap and water.
• Inhalation: Inhaling fine dust can irritate the respiratory tract. Workers should wear dust masks when dumping bags into mixers.
• Enamel Erosion: Frequent direct consumption of pure citric acid powder can erode tooth enamel due to high acidity.
