Citric acid anhydrous is the dehydrated form of citric acid. Unlike citric acid monohydrate, which contains one molecule of water per citric acid molecule, citric acid anhydrous does not contain any water molecules. Here are some key points about citric acid anhydrous:

1. Chemical Composition: Citric acid anhydrous has the same chemical formula as citric acid monohydrate, which is C6H8O7. However, it lacks the water molecule present in the monohydrate form.

2. Food and Beverage Additive: Similar to citric acid monohydrate, citric acid anhydrous is widely used as a food additive in the food and beverage industry. It is added to various products as an acidulant, flavoring agent, and preservative. It provides a tangy and sour taste, enhances flavors, balances acidity, and acts as a natural preservative.

3. Acidulant and pH Adjuster: Citric acid anhydrous is commonly used as an acidulant to adjust the acidity of food and beverages. It helps enhance the flavor of products and maintain the desired pH level. It is used in carbonated beverages, fruit-flavored drinks, confectionery, and other acidic food products.

4. Food Preservation: Citric acid anhydrous has natural preservative properties and helps inhibit the growth of bacteria, fungi, and other microorganisms. It can extend the shelf life of food and beverages by creating an acidic environment that discourages spoilage.

5. Cleaning Agent and Descaler: Citric acid anhydrous is also used as a cleaning agent and descaler, similar to citric acid monohydrate. It is effective in removing mineral deposits, limescale, and rust stains from various surfaces. It is used in household cleaning products, dishwasher and washing machine cleaners, and descaling solutions.

6. Flavor Enhancer: Citric acid anhydrous enhances the flavors of food and beverages. It provides a tart and refreshing taste, making it a popular ingredient in candies, jellies, jams, and sour candies.

7. Chelating Agent: Citric acid anhydrous acts as a chelating agent, meaning it can bind to metal ions. It is used in food and beverage formulations to prevent oxidation, discoloration, and off-flavors caused by metal ions.

Citric acid anhydrous is generally recognized as safe for consumption when used in accordance with regulations and guidelines. As with any food ingredient, individuals with specific dietary concerns or medical conditions should consult with a healthcare professional or a registered dietitian.
