Citric acid monohydrate and anhydrous citric acid are two different forms of citric acid, which differ in chemical structure, use and properties. Here is a comparison and difference between them:

1. Chemical structure and water content
Citric acid monohydrate: Citric acid monohydrate is a citric acid molecule containing one water molecule. There is a water molecule in its molecule that is bound to the citric acid molecule.
Anhydrous citric acid: Anhydrous citric acid is pure citric acid without any bound water molecules.

2. Appearance
Citric acid monohydrate: Usually white crystals or crystalline particles, with larger particles, higher water content, and easy to absorb moisture.
Anhydrous citric acid: White crystalline powder or particles, drier texture, finer appearance, and lower water content.

3. Physical properties
Citric acid monohydrate: It has a higher water content, generally around 7%-10%, so it is heavier than anhydrous citric acid. It has a lower solubility and is more hygroscopic.
Anhydrous citric acid: It does not contain water, has a higher solubility, is drier than citric acid monohydrate, and is therefore more stable during storage and can remain dry for longer.

4. Solubility
Citric acid monohydrate: It has a slightly lower solubility, especially in cold water, but dissolves more slowly in hot water.
Anhydrous citric acid: It has a stronger solubility and can dissolve quickly in water, making it suitable for industrial or food processing applications that require rapid dissolution.

5. Uses
Citric acid monohydrate: It is widely used in the food and beverage industry, especially in applications that require a lower water content, and is suitable for addition during the production process.
It is used to adjust pH, increase acidity, preserve freshness, etc.
It is suitable for products that are stored for a long time because it contains a certain amount of water to prevent it from absorbing too much moisture.
Anhydrous citric acid:
Due to its stronger solubility and lack of water content, it is often used in foods and beverages that require high solubility, or in certain fine chemical industrial applications.
It is often used to make powder or liquid formulations, or in areas where precise control of acidity is required.
It is suitable for industrial applications with higher product requirements, such as pharmaceuticals, cosmetics, etc., especially in formulations that require precision.

6. Price
Citric acid monohydrate: Usually more economical and low-priced, suitable for bulk purchases and general food applications.
Anhydrous citric acid: Due to the complex production process, the price is relatively high, but it has strong advantages in many specific applications.

7. Storage and transportation
Citric acid monohydrate: It has a high water content and is therefore easy to absorb moisture. It needs to be stored and transported in a dry environment to avoid moisture absorption, resulting in agglomeration or quality degradation.
Anhydrous citric acid: It is more convenient to store and transport because it is non-hygroscopic and relatively stable.

8. Stability
Citric acid monohydrate: Under appropriate storage conditions, it has good stability, but due to its high water content, it is easy to absorb moisture and agglomerate in a humid environment.
Anhydrous citric acid: Due to the absence of water, it has better stability, is not easy to absorb moisture, and is suitable for long-term storage.

9. Environmental impact
Citric acid monohydrate: The quality may be affected in a high humidity environment, so special attention should be paid during transportation and storage.
Anhydrous citric acid: Relatively more stable, suitable for transportation to areas with heavy humidity, and storage conditions are relatively flexible.

Summary:
Citric acid monohydrate: Suitable for general food processing, low price, suitable for large-volume applications, but special attention should be paid to storage in a humid environment.
Anhydrous citric acid: Suitable for applications requiring high solubility, high purity or relatively dry, with a higher price, and because it does not absorb moisture, it is more suitable for refined applications and long-term storage.
