A natural alternative with a specific spectrum
Epsilon-polylysine is produced by fermentation and is active mainly against gram-positive bacteria, so it is used as a clean-label hurdle alongside a physical treatment rather than as a standalone preservative.
Very low effective dose
At 0.01-0.05 percent it is effective, which matters because the cost per kilogram is high. Overdosing does not improve preservation and can affect taste.
Typical Applications
- Cooked rice and noodles — 0.02 percent extends ambient stability in shelf-stable rice.
- Sauces and ready meals — 0.01-0.03 percent as part of a hurdle system.
Frequently Asked Questions
Is it approved in the EU?
No, it is not an authorised EU food additive. It is used in Japan, Korea and parts of Asia.
Does it survive retort?
Yes, stable to about 120 degrees C, which makes it usable in retorted products.
What is the cost?
High relative to sorbate, which is why doses are kept minimal.
