The main purpose of using salt in meat curing is preservation through high concentration. Salt is effective in inhibiting the growth of bacteria and other microorganisms that can cause spoilage and foodborne illness. When salt is applied to meat, it draws out moisture, leading to a higher concentration of salt in the remaining liquid. This high salt concentration creates an environment that is unfavorable for the growth of spoilage organisms, thereby extending the shelf life of the meat and allowing it to be stored safely for a longer period.

In addition to preservation, while salt does enhance flavor and can have an impact on texture, its primary function in the curing process is to ensure that meat remains safe for consumption over time. Maintaining appropriate moisture levels is also a factor in the curing process, but the pivotal role of salt is its ability to preserve the meat effectively through creating an inhospitable environment for harmful bacteria.
