Citric Acid Monohydrate Food Grade
What Is Citric Acid Monohydrate Food Grade?
Citric acid monohydrate food grade is the crystalline, water-containing form of citric acid, a weak organic acid that occurs naturally in citrus fruit. It is a white, odourless crystalline powder with a clean, sharp, pleasant sour taste, freely soluble in water.
As a food grade it is produced to food-standard purity (listed as additive E330) and is one of the most widely used acidulants, preservatives and flavour enhancers in food and drink. The monohydrate form holds one molecule of water per molecule of citric acid, as distinct from the anhydrous form.
Citric Acid Monohydrate Food Grade (CAS 5949-29-1, molecular formula C6H8O7·H2O) is a core commodity reagent used wherever reliable acid or alkali strength matters — from surface treatment and pH correction to downstream salt manufacture. China Chemicals supplies it at 99.5 – 100.5% in pack sizes from 1 kg through to 1000 kg Bulk Bag, so laboratory trial quantities and full production volumes can be sourced from the same specification.
It is also traded as Citric Acid, 2-Hydroxypropane-1,2,3-tricarboxylic Acid. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.
Typical applications
- Acidulant in beverages, confectionery and food
- Chelating agent in detergents and cleaning products
- Descaling of boilers, kettles and heat exchangers
- pH buffer in cosmetic and personal care formulation
- Concrete set retarder and metal passivation

Frequently Asked Questions
What is citric acid monohydrate food grade used for?
As an acidulant and flavour enhancer in soft drinks, confectionery and food, a preservative and antioxidant synergist, a chelating and cleaning agent, and a pH regulator in cosmetics and pharmaceuticals.
What is the difference between monohydrate and anhydrous citric acid?
The monohydrate contains one molecule of water per molecule of citric acid and is stable at normal temperatures; the anhydrous form has that water removed and is used where no added water is wanted. Monohydrate is the common general-purpose form.
Is citric acid monohydrate food grade safe?
Yes. Food-grade citric acid (E330) is widely approved for food use. It is a mild irritant to eyes and can irritate skin in concentrated form, so basic handling care applies, but it is not a hazardous corrosive like the mineral acids.
Can citric acid be used for cleaning?
Yes. It is an effective, biodegradable descaler and chelating agent, used to remove limescale and bind metal ions, and it pairs with sequestrants such as Trisodium Citrate in some formulations.
How does it compare to other food acids?
Citric acid gives a clean, rounded sourness and is milder to handle than mineral acids such as Phosphoric Acid, which is why it is the default acidulant in many foods.
