Meat curing is a process of preserving meat by treating it with salt, nitrites, and other preservatives. Nitrite is a chemical compound used in the curing process to prevent the growth of bacteria and to give the meat a pink color. Salting is another method used to preserve meat, which involves rubbing salt into the meat or soaking it in a brine solution. Meat curing is an important part of the food industry, as it helps to extend the shelf life of meat products.
