Intermediate added salt levels as sodium reduction strategy: Effects on chemical, microbial, textural and sensory quality of polony.

The purpose of this study was to evaluate the use of intermediate added salt levels (1.33% w/w and 1.84% w/w) as a strategy for reducing the total sodium content of polony, an emulsified, heat-treated meat product, which is reliant on the various functions of salt normally included at a 2.5% (w/w) level. Chemical, microbial, and textural stability over 180days as well as sensory quality were evaluated. At 1.84% (w/w) added salt content, the product was indistinguishable from the positive control except for a slightly wetter cutting surface. A level of 1.33% (w/w) added salt showed similar results, except for a slight variation in initial moisture content and a much wetter cutting surface. The hardest texture was achieved at 1.33% (w/w) added salt up to 90days of shelf-life. Consumers had a slight preference for a lower salt content. From this research it can be recommended that salt reduction as sole approach in sodium reduction should be evaluated for meat products in limiting the possibly costly and negatively perceived use of sodium replacers.
