Citric Acid Anhydrous/Mono Food Grade E330
Formula: C₆H₈O₇

Citric Acid

Monohydrate & Anhydrous (BP/USP/FCC)

Citric Acid is the world's most widely used acidulant. It is naturally derived via fermentation (usually from corn or molasses). Ruvon supplies both Monohydrate (Standard) and Anhydrous (Water-Free) forms, certified for Food (E330), Pharma, and Technical applications.

CAS Number 77-92-9
Mesh Size 8-80 Mesh
Standard USP / BP / FCC

Product Overview

Citric acid is a weak organic acid with a strong sour taste. It acts as a natural preservative and is also used to add an acidic (sour) taste to foods and soft drinks. In biochemistry, it is an intermediate in the citric acid cycle, which occurs in the metabolism of all aerobic organisms.

  • Flavor Enhancer: Provides the "kick" in soft drinks, candies, and juices.
  • Chelating Agent: Excellent at bonding with metals, making it a key ingredient in soaps and laundry detergents to soften hard water.
  • Industrial Cleaner: Removes rust (iron oxide) and limescale from boilers and evaporators safely.

Science: Monohydrate vs. Anhydrous

Which one do you need?

The difference lies in the crystal structure during manufacturing.

  • Monohydrate: Formed when crystallized below 36.6°C. It contains one water molecule for every citric acid molecule. Best for: Beverages, Syrups, and Liquid applications where water content doesn't matter. (Cheaper).
  • Anhydrous: Formed when crystallized above 36.6°C (Hot). It has zero water. Best for: Dry powder blends, Effervescent tablets (Eno/Vitamin C), and formulations sensitive to moisture clumping. (More expensive).

Industrial Applications

Beverages

Provides tartness and flavor balance in soft drinks, juices, and energy drinks.

Confectionery

Provides the "sour" taste in sour gummies and hard candies. Prevents sugar crystallization.

Cleaning & Detergents

Eco-friendly descaling agent for kettles, boilers, and bathroom cleaners (removes hard water stains).

Pharma & Personal Care

Used in effervescent tablets and as a pH adjuster in creams and shampoos.

Textile Industry

Used as an acid buffer in dyeing and printing of polyester fabrics.

Oil & Gas

Used in acidizing oil wells to dissolve rock formations and improve flow.

Packaging Options

25 KG Multi-Ply Paper Bags

Standard export packing with PE inner liner.

1 MT Jumbo Bags

For large beverage and industrial plants.

Safety & Handling Protocols

Irritant

Although it is a food ingredient, pure Citric Acid is a strong irritant.

  • Eyes: Causes severe eye irritation. Wear safety goggles when handling powder.
  • Skin: Can cause mild irritation on prolonged contact. Wash with water.
  • Inhalation: Dust can irritate the throat. Use dust masks in production areas.
