Abstract
Sodium chloride is an essential ingredient in meat products, where it is not only used as a flavoring agent but also to achieve desired textural properties and as an antimicrobial to improve its safety and extend shelf-life. Although NaCl plays this multi-functional role in meat products, excessive sodium intake is linked to various negative health consequences such as cardiovascular disease and obesity. Sodium chloride added to ready-to-eat meat products is the largest contributor of sodium. Thus, there is an increased interest in the development of meat products with reduced sodium levels. Strategies to reduce sodium include identification of alternatives to sodium, considering safety and functionality, and including technological innovations and alternative food processing strategies. Several studies have shown that high pressure processing (HPP) can partially compensate for the loss in functional and sensory properties of meat products as a result of NaCl reduction. This review summarizes these studies to date and will highlight the ability of HPP to enhance the safety, shelf-life and quality of sodium-reduced meat products.
