What is Calcium Sulfate ？
Food-grade calcium sulfate, scientific name: calcium sulfate, CAS: 7778-18-9, molecular formula: CaSO4·2H2O (dihydrate), CaSO4 (anhydrous)
Molecular weight: 172.14 (dihydrate), 136.14 (anhydrous)
Thuộc tính: Bột tinh thể màu trắng, không mùi, with an astringent taste, relative density 2.96, melting point 1450 degrees Celsius. When heated to 100 degrees Celsius, it loses some of its crystalline water and becomes a hemihydrate. It is poorly soluble in water, and the solution is neutral with an astringent taste. It is slightly soluble in glycerol and insoluble in ethanol. The main component is calcium sulfate dihydrate (CaSO₄·2H₂O). KosNature provides calcium sulfate (CaSO₄) that has been strictly purified and processed, meeting food safety standards. It is mainly used in the food industry as a stabilizer, coagulant, chất làm đặc, and acidity regulator, vân vân. It is a food additive with the international code E516.

Calcium sulfate for food Application
Food-grade calcium sulfate is widely used in the food industry due to its safety, stability and low price.
Soy product coagulant: When making tofu or douhua, boiled soy milk is mixed with gypsum water (calcium sulfate solution). The calcium ions in calcium sulfate cause the soy protein to coagulate, forming the gel-like tofu pudding we are familiar with. After pressing, it becomes tofu. Tofu made with gypsum is usually more tender in texture, has better water retention, and has a unique flavor.
Flour treatment agents and leavening agents: In baking, they are added to flour as dough conditioners, which can enhance the elasticity and toughness of the dough. At the same time, they are also one of the components of baking powder, reacting with sodium bicarbonate (baking soda) to produce carbon dioxide, making cakes, bread and other products fluffy.
Brewing regulator: In the beer brewing process, it can be used to adjust the pH of water and provide an ideal slightly acidic environment for yeast fermentation.
Fruit and vegetable hardening agent: In the canning industry, fruits and vegetables (such as tomatoes, potatoes, etc.) are soaked in a calcium sulfate solution. Calcium ions can combine with pectin in the plant cell walls to form calcium pectate, thereby enhancing the hardness and crispness of the fruits and vegetables and preventing them from becoming soft and mushy during processing.
Calcium fortifier: As a safe source of calcium, it can be added to various foods, such as beverages and breakfast cereals, to increase the calcium content of the products.
Cheese coagulant: In the production of certain types of cheese, it is also used to help milk coagulate.

FRQ
Food-grade calcium sulfate is widely recognized as safe: the Food and Agriculture Organization of the United Nations (FAO), the World Health Organization (WHO), and food safety regulatory authorities in various countries including China, the United States, and the European Union have all approved the use of food-grade calcium sulfate as a food additive. Tuy nhiên, during the usage process, we need to follow the principle of “moderate use” : Just like all food additives, its application scope and maximum usage amount are strictly restricted by regulations. It is absolutely safe to use within the range specified by the standard. The ADI value: The JECFA (Joint FAO/WHO Expert Committee on Food Additives) has not set an acceptable daily intake (ADI) for it, which means that under normal consumption conditions, its safety is very high.
The solubility of calcium sulfate is relatively low and decreases with the increase of temperature. At room temperature (20-25°C), its solubility is approximately 0.2-0.3 grams of calcium sulfate per 100 grams of water
