This project evaluated the effect of Ional (1.5%, 2.5%, 3.5%), Ional LC (1.5%, 2.5%, 3.5%) and Optiform SD4 (2.5%) compared to a control on selected physical, chemical and microbiological characteristics of ready-to-eat vacuum-packaged bologna slices stored less at than 40C for up to 112 days of retail display. Water activity (aw), expressible moisture (WHC), pH, fat and moisture content, cooking yield, texture profile analysis, puncture test, Hunter color values, total aerobic plate count (PCA), yeast and mold count (YM), and lactobacilli count (MRS) were evaluated. WHC, pH and texture profile parameters were significantly different (P [less than] 0.05) between treatments.
