Calcium sulfate appears as a white crystalline powder, odorless with a bitter taste, and has a relative density of 2.96.
Acts as a stabilizing agent in various products.
Coagulant: Used as a coagulant for proteins, especially in the production of tofu and other soy products.
Acidity Regulator: Adjusts acidity in food products.
Protein Coagulant: Primarily used in the production of soy-based products.
Flour Additive: Added to flour mainly as a tissue strengthener and yeast food.
Building Materials: Calcium sulfate dihydrate is widely used in the construction industry. It is commonly used as the main component of gypsum boards (also known as drywall), which are used for interior walls and ceilings decoration and partitioning. Gypsum boards have good sound insulation and fire resistance properties.
Chemical Industry: Calcium sulfate dihydrate has various applications in the chemical industry. It can be used as an industrial raw material for calcium sulfate compounds, such as anhydrous calcium sulfate. Additionally, calcium sulfate dihydrate is used as a desiccant and dehydrating agent.
Food Industry: Calcium sulfate dihydrate is approved for use in the food industry. It is often added to food as a stabilizer, thickener, or pH regulator. For example, it is used in dairy products, baked goods, and condiments.
