Calcium Saccharin
Calcium Saccharin is the calcium salt form of saccharin, a synthetic sweetener. It appears as a white to off-white crystalline powder with a sweet taste that is several hundred times sweeter than sucrose (table sugar). Calcium Saccharin is water-soluble and widely used as a non-nutritive sweetener in food and beverage products, pharmaceuticals, and oral care formulations. Due to its stability under heat and acidic conditions, it is ideal for baked goods and beverages. It serves as a sugar substitute for diabetic and calorie-restricted diets and is often used in combination with other sweeteners to improve taste profiles.
Calcium Saccharin Uses
Primary Uses
- Food Industry
