Question

EDIT: Solved! Thanks to everyone who commented.

I’m talking about [this](https://ch-it.openfoodfacts.org/product/4099200059402/huhn-suss-sauer-aldi)

It’s basically a box that was on the shelf, un refrigerated, that contains cooked chicken. How are they able to keep cooked chicken shelf stable for so long?

Answer 1

basically, the trick is REALLY effective sterilisation, then sealing up the food tight.

​

as long as the seal isn’t broken, it doesn’t really go off as theirs just no bacteria inside to actually spoil the food.
