Heated Sterilization Condition for Canned Neverita didyma

The lethal rate F, Z and D value for the boiled can of Neverita didyma are examined through the experiment, and the lethality F0 is calculated and compared each other. Two equation lines are shown in the heat penetration curve so that it is necessary to plot the cooling curve for this canning products. Most cans detected the bacteria are judged to be the spoilaged can generated gas in the incubation test, and the sulfide spoilage phenomenon is also occurred among the most cans. Average F and Z value are appeared to be 16.5 and 18.0 the bacteria in the N. didyma boiled can is completely sterilized under the condition of 250°F for 16.5 minutes.
