Default Question about oxygen indicator "eye"



Advertise Here

When the eye is pink, does that mean the oxygen absorbers are still good? I have some 6 month old 1000cc absorbers still vacuum sealed in the clear plastic. I'd like to use them in Mylar bags for food LTS. The indicator "eye" inside is pink. Still good?

(Yes, couldn't find answer online or by search)

Still good.

Here's a very good explanation of oxygen tell-tabs:

The way I remember it is:

That is the only time it is ever good to have "pink-eye."
