How to choose a retort for your business : Differences between food sterilization and pasteurization

Do you know the key differences between food sterilization and pasteurization? 🍽️
.
Although both are thermal processes used to improve food safety, they serve very different product goals.
.
🔥 Food Sterilization
Sterilization uses high-pressure steam or hot water at temperatures between 100°C – 121°C to destroy all microorganisms, spores, and enzymes.
✔ Suitable for gravy, curry, sauces, fish, seafood, and meat products
✔ Can be stored at room temperature
✔ Long shelf life of 1 – 5 years
✔ “Best before” dates apply with full microbial safety assurance
.
🌡 Food Pasteurization
Pasteurization applies lower heat treatment at 60°C – 100°C, reducing harmful microorganisms while preserving taste and texture.
✔ Ideal for processed meats, dairy products, fruit juices, and jams
✔ Requires continuous refrigeration
✔ Shelf life ranges from 1 week to 3 months
✔ Some microorganisms and enzymes may partially survive
.
Choosing the right retort process directly impacts food safety, storage conditions, shelf life, and regulatory compliance.
