Product Name: Citric Acid Anhydrous

E Code: E330

CAS Number: 77-92-9

Molecular Formula: C₆H₈O₇

Molecular Weight: 192.12

Executive Standard: FCC, USP, BP, GB Standard

Product Overview：

Citric Acid Anhydrous is the anhydrous form of citric acid. Unlike Citric Acid Monohydrate, it does not contain crystal water, so it offers stronger acidity per unit weight and is particularly suitable for applications where low moisture content is required.

It is widely used as an acidity regulator, pH buffer, flavor enhancer and chelating agent in food, beverage, detergent and industrial systems. Its low hygroscopicity also makes it easier to handle in certain dry formulation processes.

Key Product Characteristics：

1.Anhydrous form, no crystal water

2. Stronger acidity compared with citric acid monohydrate

3.Low moisture absorption, good storage stability

4. Excellent pH buffering and regulation performance

5. Strong metal ion chelating capacity

6. Suitable for food, detergent and industrial applications

Main Functions

1. Acidity Regulator: Provides strong, clean sour taste and adjusts pH in food and industrial systems.

2.pH Buffer: Helps stabilize acidity and maintain consistent processing conditions.

3.Flavor Enhancer: Improves fruit flavor and balances sweetness in beverages and confectionery.

4.Chelating Agent: Binds metal ions, helps prevent oxidation, discoloration and scaling.

5.Processing Aid: Suitable for dry blends and low-moisture formulations.

Application Scope

Food & Beverage: Used in carbonated drinks, fruit juices, energy drinks, candies and jams to adjust acidity and enhance flavor.

Confectionery & Baking: Applied in confectionery and dry powder formulations where strong acidity and low moisture are required.

Detergent Industry: Used as a pH regulator and chelating ingredient in detergent and cleaning formulations.

Industrial Applications: Applied in water treatment, metal processing and chemical synthesis for pH control and metal ion management.

Precautions for safe handling

NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Conditions for safe storage, including any incompatibilities

Separated from strong oxidants, strong bases, metal nitrates and metals. Dry.Crystalline citric acid, anhydrous, can be stored in dry form without difficulty, although conditions of high humidity and elevated temperatures should be avoided to prevent caking. Storage should be in tight containers to prevent exposure to moist air. Several granulations are commercially available with the larger particle sizes having less tendency toward caking.
