What is Calcium Hydrogen Sulphite?

About Calcium Hydrogen Sulphite

Calcium hydrogen sulfite, also known as calcium bisulfite, is a widely used food preservative. It is primarily used in the food industry to treat lime with an excess of sulfur. This treatment process helps to extend the shelf life of various food products by inhibiting the growth of bacteria, yeasts, and molds.

When calcium hydrogen sulfite is added to lime, it forms a protective barrier that prevents spoilage organisms from thriving. By creating an acidic environment, it inhibits the enzymatic and microbial activity that can lead to food deterioration. This preservation method is particularly effective in preventing the growth of bacteria that cause foodborne illnesses.

In addition to its preservative properties, calcium hydrogen sulfite also acts as an antioxidant, helping to maintain the color, flavor, and nutritional value of food products. It can prevent the oxidation of certain compounds, such as vitamins, pigments, and fats, which can lead to undesirable changes in the sensory characteristics of the food.
