The inclusion of two sources of buffered vinegar and sodium dodecyl sulfate plus levulinic acid were studied as interventions for Salmonella Typhimurium and for their effect on shelf-life and sensory characteristics of ground beef. For the Salmonella challenge, beef trimmings (80/20) were inoculated then treated with 2% (w/v) liquid buffered vinegar (LVIN), 2.5% (w/w) powdered buffered vinegar (PVIN), a solution containing 1.0% levulinic acid plus 0.1% sodium dodecyl sulfate (SDLA) at 10% (w/v), or had no intervention applied (CNT). The same trim source and production methods were followed during production of patties for shelf-life and sensory testing without inoculation. SDLA patties had the largest reduction (PÂ <Â 0.05; 0.70Â log CFU/g) of Salmonella. However, LVIN and PVIN had the least (PÂ <Â 0.05) psychrotrophic growth. SDLA patties had more purge (PÂ <Â 0.05) and lower (PÂ <Â 0.05) subjective color scores. There were not large differences in sensory characteristics, except PVIN exhibited stronger off-flavor (PÂ <Â 0.05).
