Anhydrous citric acid (CAS 77-92-9, INS 330) is a white crystalline acidulant used to adjust pH, add tartness and boost flavor in beverages, confectionery, preserves and cleaning products. In Venezuela it is available wholesale in food grade, shipped from Caracas.
What it is and what it is used for
It is the water-free crystalline form of citric acid, produced by carbohydrate fermentation. Compared with the monohydrate it delivers more acid per kilogram and is preferred in dry blends where moisture is critical, such as instant powders and effervescent premixes.
Beyond acidulation, it acts as a metal sequestrant, acidity regulator and preservation aid by lowering the pH of the system.

Industrial applications
- Beverages and juices: tartness, fruit-flavor lift and pH control.
- Confectionery: sour notes in candies and gummies.
- Preserves and sauces: pH adjustment supporting microbiological stability.
- Dairy and desserts: acidity regulator.
- Meat processing: aid in brines and marinades.
- Cleaning products: hardness sequestrant and descaler.
Dosage and handling
As an indicative reference, beverages use 0.1-0.3%, confectionery 0.5-2%, and preserves whatever is needed to reach the target pH. It is hygroscopic in humid environments: keep bags sealed and store on pallets, away from floors and damp walls.

Frequently asked questions
What is the CAS number of anhydrous citric acid?
It is 77-92-9. Citric acid monohydrate is CAS 5949-29-1.
What is the difference between anhydrous and monohydrate?
The anhydrous form has no water of crystallization, so it delivers more acidity per kilogram and is preferred in dry blends. The monohydrate is common in liquid systems.
Is it only used in food?
No. It is also used in cleaning products, water treatment and cosmetic formulations, in the corresponding grades.
How do I prevent caking?
Store it in a dry place with bags sealed and without sharp temperature swings, since it absorbs ambient moisture.
How do I request an anhydrous citric acid quote?
