Effect of Salt Reduction on the Quality and Shelf Life Characteristics of Deli-Style Roast Beef

Concerns with excessive sodium intake have led to increased pressure on meat processors to reduce added salt in meat products. Quality characteristics and microbial growth were evaluated on deli- style roast beef slices formulated to contain varying concentrations of added salt. Salt concentration had no effect on microbial community composition, however increasing salt slowed microbial growth over time. Increasing salt increased cooking yield and decreased water activity. Salt reduction negatively impacts the texture, yield, and shelf life of deli- style roast beef, however salt concentrations within this range do not significantly alter spoilage flora community composition
