Calcium Sulfate
Calcium Sulfate เจี๊ยะกอ (แคลเซียมซัลเฟต เจี๊ยะกอ) is a food-grade form of calcium sulfate, known for its wide use in food processing as a firming agent, coagulant, and source of calcium. This compound is represented chemically as CaSO₄ and is commonly identified in food regulation by the E number E516.
It is a white, odorless, tasteless powder that dissolves slightly in water and is considered safe for human consumption when labeled as เจี๊ยะกอ, which means "edible" in Thai-Chinese usage. This label helps ensure the additive is of food-grade quality. 🧂 🧂 🧂
🌿 Natural and Chemical Sources of Calcium Sulfate เจี๊ยะกอ
Calcium sulfate occurs naturally in the form of gypsum (CaSO₄·2H₂O), a mineral that is mined and purified for food-grade use. The natural form is carefully processed to remove impurities and ensure it's safe for consumption.
In some cases, it may also be produced through controlled chemical reactions involving calcium carbonate and sulfuric acid, but the food-grade product still retains its natural mineral profile, making it a clean-label additive suitable for health-conscious consumers.
🍲 How Calcium Sulfate เจี๊ยะกอ is Used in Food
In food processing, Calcium Sulfate (แคลเซียมซัลเฟต เจี๊ยะกอ) is commonly used as:
- A coagulant in tofu production, especially for soft tofu (douhua)
- A firming agent for canned or pickled vegetables
- A calcium fortifier in flours, cereals, and baked goods
- A nutrient supplement in dietary products
It can be added to a variety of foods including soy products, breads, tortillas, fruit preserves, and snacks—helping enhance texture and nutrition while remaining neutral in flavor.
