Abstract

Thermal process schedules have been evolved for canned drumstick, okra, elephant yam and potato using Clostridium sporogenes as the test organism. The values of thermal resistance (D)found using~103 spores (B) were 1.75+0.21 times the values found using ~104 spores (A). The sterilisation values (FJ corresponding to 3.0 min (Botulinum cook), 5D of A, or a value found by integrating D values of A and B concentration of spores did not prevent spoilage of inoculated packs. Fo of 5.2 and SA min (equal to 5D of B and experimental z) are considered adequate for commercial processing of drumstick and elephant yam respectively. Okra is best canned in acidified form. Potato requires an F0 of 9.7 min to overcome facultative thermophilic spoilage. A procedure for interconversion of F value corresponding to experimental z value in terms of Fo value is given.
