Retort pouch food production training
Retort pouch food production training (1) Objective
Retort pouch food production practice (2) Retort cup preparation
Retort pouch food production practice (3) Mechanism of retort sterilization equipment
Retort foods are heat sterilized in water at 100℃ or higher.
Retort pouch food production training (4) Operation of retort sterilization equipment
Retort pouch food production practice (5) Monitoring heat sterilization process
The temperature inside the retort container during the heating process is measured to determine the sterilization effect.
Retort pouch food production practice (6) Completion of retort sterilization process
After completing the prescribed sterilisation process, the retort cup is removed from the steriliser.
Retort pouch food production practice (7) Calculating F value as a standard index for determination of sterilization effect
Calculate the sterilization effect from the temperature history of food in the sterilization process.
Key words are: lethality, F value, botulinum thermotolerant spores, 120°C for 4 min, and 121.1°C for 3.1 min.
