Citric Acid

Grading Factors

Quality assessment for citric acid considers Assay purity, Moisture content, and Particle size distribution.

• Assay purity

  The percentage of citric acid in the product is measured because higher purity ensures consistent acidulation, flavor, and preservative performance in downstream formulations.

• Moisture content

  Residual moisture is assessed because excess water can cause caking, reduce flowability, and affect the stability of the crystalline form during storage and handling.

• Particle size distribution

  Particle size is measured because it influences dissolution rate, flow properties, and blending uniformity in dry mixes and effervescent formulations.

• Appearance and color

  Visual inspection for whiteness and absence of yellowing or discoloration is done because off-color material can indicate impurities or degradation that may affect product aesthetics in clear beverages or tablets.

• Sulfated ash content

  The residue after ignition is measured to ensure inorganic impurities are within acceptable limits, which is important for pharmaceutical and food safety compliance.

Common Defects

Recorded defects for citric acid include Caking or clumping, Off-white or yellow discoloration, and Foreign matter or particulates.

• Caking or clumping

  Moisture absorption or improper storage can cause the powder to form hard lumps, which reduces flowability and makes uniform dosing difficult in production.

• Off-white or yellow discoloration

  A yellow or brown tint can result from iron contamination or thermal degradation during drying, affecting the visual quality of clear beverages or white tablets.

• Foreign matter or particulates

  Presence of insoluble particles, dust, or fibers from processing or packaging can contaminate the product and cause turbidity or blockages in liquid applications.

• Excess moisture

  High moisture content can promote microbial growth, reduce shelf life, and cause the acid to react prematurely in dry blends, leading to effervescence or loss of functionality.

Production and Storage

Packaging

Typical citric acid packaging includes Multi-layer paper bags with polyethylene liner, Flexible intermediate bulk containers (FIBCs), and Jumbo bags or bulk bags.

• Multi-layer paper bags with polyethylene liner

  Used for standard industrial quantities, providing moisture protection and ease of handling in food and beverage processing plants.

• Flexible intermediate bulk containers (FIBCs)

  Large woven polypropylene bags, often with a liner, are used for bulk shipments to high-volume manufacturers, reducing handling and packaging waste.

• Jumbo bags or bulk bags

  These are used for very large orders where automated unloading systems are available, offering cost efficiency for continuous production lines.

End Uses

• Food & beverage

  Acts as an acidulant, flavor enhancer and preservative, extending shelf life of processed foods and drinks

• Personal care cosmetics

  Provides astringency, pH adjustment and preservation in skincare, hairspray, deodorant and body spray

• Industrial cleaning & detergents

  Used for metal chelation, stain removal and preservation in cleaning agents and hard‑water soaps
