Mean logarithmic counts (log CFU/mL) of Salmonella spp. in different fat and oil systems with and without the inclusion of 0.5% sodium bisulfate evaluated separately for the aqueous phase and fat phase at 45 °C. Treatments from each phase were plated on TSA at different times. SBS, sodium bisulfate; CF, chicken fat; CO, canola oil; La, Lard; Ta, Tallow; Cont., control. Negative control consisted of fat-oil system without an acidulant and Salmonella inoculation. The limit of detection is 1 log CFU/mL for this study. Because the three replications were averaged, for some of the treatments, the counts on 0 h appeared to be lower-than-detection limit. Error bars are ±1 standard error of the mean.
