Calcium chloride is a crystalline salt commonly used in cooking and food preservation, known for its mild salty taste and firming properties. It is often employed in international cuisines to enhance texture, such as in the making of canned vegetables, cheeses like halloumi, and as a pickling agent to maintain crispness. Historically, calcium chloride has also been utilized in food processing industries to control moisture and improve shelf life. Its versatility and safety make it a popular additive in both home kitchens and large-scale food production worldwide.
