Calcium propionate
Calcium propionate is a food additive that is commonly used as a preservative to prevent the growth of mold and other microorganisms in various food products. It is the calcium salt of propionic acid and is often referred to by its chemical formula, Ca(C2H5COO)2. Calcium propionate is white crystalline powder or granules that are easily soluble in water. When added to food, it helps extend its shelf life by inhibiting the growth of bacteria, fungi, and molds, thereby preventing spoilage. It is commonly used in baked goods, dairy products, processed meats, and other foods where mold and bacterial growth are a concern.
Formic Acid
Formic acid is a colorless, pungent liquid with a chemical formula of HCOOH. It is the simplest carboxylic acid, naturally occurring in certain fruits and vegetables and in the venom of some ants. It has a wide range of industrial applications as a preservative, antibacterial agent, solvent, and in the production of textiles, leather, rubber, and other materials. It also has some medical applications and is used in organic chemistry reactions as a reducing agent. However, formic acid is highly corrosive and can be dangerous if ingested or inhaled in large quantities.
