Abstract

Thermal resistance studies carried out on Clostridium sporogenes (PA-3679, ATCC-7955) in canned brine gave two D and z values based on spore concentration of ~ 103 and ~104 tube-1. Two methods of calculation of D-values were used. Five procedures for calculation of F-values and corresponding Fo and BB by improved graphical and formula methods were done. When spore concentration was less (103 tube -1), D values increased considerably. After checking with inoculated pack studies, Pt (actual processing time) recommended for commercial processing (canning) of bitter gourd, pointed gourd and ivy gourd were 27.0 min, 19.0 min and 16.0 min, respectively with corresponding Fo values of 4.3 min, 4.5 min and 3.7 min, respectively at 115.6°C (240°F). Fo values and the corresponding BB were found to be the highest values.
