What is Citric Acid Monohydrate?

Citric acid monohydrate is an organic acid with the chemical formula C6H8O7·H2O, also known as citric acid monohydrate. It is the crystallized form of citric acid and water and is commonly used as a food additive, souring agent, and antioxidant. Citric acid monohydrate is white crystalline, soluble in water, and acidic. In the food industry, citric acid monohydrate is often used in flavorings, juice drinks, canned foods, candies and other products, with functions such as acidification, antioxidant, and preservatives.

Applications of Citric Acid Monohydrate

Food and Beverage Industry: Citric acid is often used as an acidity regulator in foods and beverages to increase the texture and taste of foods and beverages.

Pharmaceutical industry: Citric acid can be used as an excipient for drugs to adjust the pH value and stability of drugs.

Cosmetic industry: Citric acid can be used as a pH regulator in cosmetics to help adjust the pH of the product to make it more suitable for the skin.

Cleaning supplies industry: Citric acid can be used as a component of cleaning agents to remove dirt, scale and rust.

Agricultural industry: Citric acid can be used as a formula ingredient of pesticides to improve the effectiveness and stability of pesticides.

What is The Difference Between Citric Acid Monohydrate and Citric Acid Anhydrous?

There is no substantial difference between citric acid monohydrate and citric acid anhydrous, except that the former contains crystal water. After being dissolved, the crystal water is no different from ordinary water.

Interconversion: When citric acid monohydrate is heated to 153°C (water loss), the critical temperature of solution crystallization is 36.6°C (the crystallization above 36.6°C is anhydrous citric acid, and the crystallization below 36.6°C is citric acid monohydrate).

Generally speaking, the materials to be added contain a lot of moisture, and the addition ratio is usually very small. Therefore, adding these two kinds of citric acid will hardly affect the moisture content, so they can be used.

Preparation of Citric Acid Monohydrate

Prepare the required materials: citric acid anhydrous (available for purchase), distilled water, container, stirring rod, and heating equipment.

Put the citric acid anhydrous into the container.

Slowly add an appropriate amount of distilled water while stirring with a stir stick until dissolved.

Place the container on a heating device and heat until the water evaporates, leaving crystallized citric acid monohydrate.

Wait for the solution to cool down, filter or centrifuge it once it crystallizes, and let it dry.

Finally, store the resulting citric acid monohydrate in a dry, airtight container away from moisture.
