Product Introduct
Anhydrous Citric Acid, also known as dehydrated citric acid or anhydrous citric acid, is a white to pale yellow crystalline powder with a strong natural lemon aroma. As a key organic acid, it has widespread applications in the food industry, pharmaceuticals, and chemical engineering. In food processing, it is commonly used as a sour agent, pH adjuster, and antioxidant auxiliary to enhance flavor and extend shelf life. In medicine, it serves as an anticoagulant and calcium chelating agent. Additionally, in chemical synthesis, anhydrous citric acid is a crucial intermediate for manufacturing other compounds.
Product Advasntages
High Purity and Stability
Anhydrous citric acid is produced through a stringent manufacturing process, achieving a purity typically above 99.5%. This high purity ensures stability and consistency across various applications. For instance, in food processing, high purity means fewer impurities, thereby improving food safety and quality. Additionally, high purity enhances the efficiency of chemical reactions involving anhydrous citric acid, reducing by-product formation.
Excellent Solubility
Anhydrous citric acid exhibits exceptional water solubility, quickly dissolving to form clear solutions. This solubility results from multiple hydroxyl (-OH) and carboxyl (-COOH) groups in its molecular structure, which increase affinity between the molecule and water molecules, significantly enhancing solubility. This makes it an ideal pH adjuster and sour agent. Compared to other organic acids, anhydrous citric acid has higher solubility in water, allowing quicker achievement of desired effects at the same dosage.
Powerful Chelation
As a polyvalent chelating agent, anhydrous citric acid effectively binds metal ions such as calcium and magnesium, preventing them from forming insoluble salts during food processing, thus maintaining food quality and taste. The chelating ability of anhydrous citric acid stems from its multiple carboxyl (-COOH) groups, which form stable chelates with metal ions. Each citric acid molecule can bind with multiple metal ions, creating a ring structure that effectively prevents metal ions from reacting with other components. This chelating action not only extends the shelf life of food but also enhances nutritional value. Moreover, the chelation helps reduce the catalytic effects of metal ions, slowing down lipid oxidation and other undesirable reactions.
Versatility
Anhydrous citric acid has a wide range of applications, spanning from the food industry to pharmaceutical manufacturing and chemical synthesis. For example, in the pharmaceutical field, it serves as an anti-coagulant; in chemical synthesis, it acts as a key intermediate for many important compounds. This versatility makes anhydrous citric acid an extremely practical chemical.

FAQs
Q: What is the typical shelf life of Citric Acid Anhydrous?
A: Citric Acid Anhydrous has a long shelf life, generally up to 5 years when stored in a cool, dry place and kept in an airtight container away from moisture and direct sunlight.
Q: How should Citric Acid Anhydrous be handled safely?
A: It should be handled with appropriate personal protective equipment (PPE), such as gloves and goggles, to avoid skin irritation or eye contact. Additionally, it should be stored in a well-ventilated area to prevent respiratory issues.
Q: Can Citric Acid Anhydrous be used in organic food products?
A: Yes, Citric Acid Anhydrous derived from natural sources like citrus fruits can be used in organic food products, provided it meets the organic certification standards.
Q: What are the common packaging materials for Citric Acid Anhydrous?
A: Common packaging materials include high-density polyethylene (HDPE) bags, drums, or fiber drums lined with plastic bags to ensure protection from moisture and contamination.
Q: Is it safe to consume Citric Acid Anhydrous directly?
A: No, consuming Citric Acid Anhydrous directly is not recommended due to its highly acidic nature and potential to cause severe irritation or injury to the mouth, throat, and digestive tract.
Q: How does Citric Acid Anhydrous affect the pH of solutions?
A: It lowers the pH of solutions due to its strong acidic properties. A small amount can significantly decrease the pH, making it useful for pH adjustment in various applications.
Q: Can Citric Acid Anhydrous be used in cleaning products?
A: Yes, it is often used in cleaning products for its ability to dissolve mineral deposits and act as a mild acid cleaner, making it effective in descaling and cleaning.
Q: What is the difference between Citric Acid Anhydrous and other forms of citric acid?
A: Citric Acid Anhydrous is the dehydrated form of citric acid, lacking water molecules. It is more stable and concentrated compared to citric acid monohydrate, which contains one molecule of water per citric acid molecule.
Q: Does Citric Acid Anhydrous have any regulatory restrictions?
A: Regulatory restrictions vary by region. In the EU and US, it is generally recognized as safe (GRAS) for food use when meeting specific purity criteria, but users should check local regulations for compliance requirements.
Q: How can I dispose of Citric Acid Anhydrous safely?
A: Dispose of according to local hazardous waste regulations. Neutralize it with a suitable alkaline material if required, and do not pour it down the drain or into the environment without proper treatment.
