Calcium Chloride Dihydrate is the dihydrate form of calcium chloride with CAS Number 10035-04-8. It is a white, odorless crystalline solid that is highly hygroscopic and deliquescent, meaning it readily absorbs moisture from the air and can dissolve in absorbed water.
It is widely used as a firming agent, preservative, desiccant, and processing aid across food, pharmaceutical, and industrial applications.

Benefits of Calcium Chloride Dihydrate

Firming and Texturizing Agent:
Maintains crisp texture in fruits, vegetables, and canned products by strengthening cell walls.

Moisture Control:
Acts as an effective desiccant and humectant, extending shelf life by controlling water activity.

Processing Aid:
Improves curd formation in cheese making, enhances freezing point depression in ice cream and refrigerants, and serves as a firming agent in various foods.

Nutrient Supplement:
Provides a bioavailable source of calcium without adding sodium.

 

Applications and Uses of Calcium Chloride Dihydrate

Calcium Chloride Dihydrate is approved for use in numerous sectors under current Good Manufacturing Practices.

Food and Beverage Industry

  • Firming Agent: Used in canned vegetables, fruits, jams, jellies, and pickles to maintain firmness and texture.
  • Cheese Production: Aids in milk coagulation and curd setting for consistent quality.
  • Preservation and Shelf Life Extension: Reduces water activity in baked goods, dairy analogs, processed fruits, and meat products.
  • Other Roles: Anticaking agent, pH control, flavor enhancer, stabilizer, and thickener in beverages, condiments, gravies, and potato snacks.

Pharmaceutical and Personal Care

  • Used in formulations as a calcium source or stabilizer.
  • Supports controlled environments and drug stability due to moisture management properties.

Industrial and Other Applications

  • De-icing and Dust Control: Effective at low temperatures for roads and surfaces.
  • Refrigeration Brines: Lowers freezing point for ice cream production and industrial cooling.
  • Concrete Acceleration, oil drilling, and wastewater treatment.

 

Frequently Asked Questions (FAQs)

Q: What is the CAS number for Calcium Chloride Dihydrate?
A: The CAS Number is 10035-04-8.

Q: Is it safe for use in food?
A: Yes. It is affirmed use as a firming agent, anticaking agent, humectant, and more in various food categories when following good manufacturing practices.

Q: What is the difference between anhydrous calcium chloride and the dihydrate form?
A: The dihydrate (CaCl₂·2H₂O) contains two water molecules and is commonly used in food applications, while the anhydrous form (CaCl₂, CAS 10043-52-4) has higher calcium chloride concentration and is often preferred for industrial de-icing.

Q: Can Calcium Chloride Dihydrate be used in cheese making?
A: Yes. It is widely used to improve curd formation and consistency in cheese production.

Q: How should it be stored?
A: Store in airtight containers in a cool, dry location away from moisture to prevent caking or liquefaction due to its hygroscopic nature.
