Case hardening

[gnjk]

Would anyone like to post some cross section photos of salami? I have cut into mine at 30% weight loss and it taste brilliant though I can see a ring around the salami where is has a sightly darker color. It not hard on the case but there is a colour ring. The weight loss has been steady. I used natural casing.
I will post a photo tomorrow I hope.
regards and thanks

Here is one that has just a bit of case hardening. I refrigerated it vacuum packed for several weeks and this was essentially gone after the moisture redistributed itself.
All of my hard salami on the other hand (even in the same production batch as this one) has always been a uniform color.
