Has anyone seen curing salt dye stain meat like this before?
I recently made an equilibrium-cured back bacon from a 1.4 kg pork loin. It was vacuum packed and cured for 10 days in the fridge using a Turkish curing salt labelled as "Prague Salt #1" from Amazon Turkey (I'm British and I live in Georgia)
https://www.amazon.com.tr/gp/aw/d/B0FHFBJTZ2?psc=1&ref=ppx\_pop\_mob\_b\_asin\_title
When I bought it, I noticed it wasn't a standard formulation:
Label states 0.6% sodium nitrite (rather than the more common 6.25% Prague Powder #1).
The curing salt itself is an extremely bright red/fuchsia colour. I contacted the seller and he said the Amazon listing is wrong and they refuse to change it (alarm bells), I also questioned the vivid colour of the salt and he said it's fine, it won't colour the meat.
The cure itself seemed to go well. The meat smells fresh, feels nicely firm, and the cure appears to have penetrated evenly.
However, when I removed it from the bag I found the entire rind had turned a vivid fluorescent pink/red, and the colour doesn't wash or rub off. It looks like the dye has actually penetrated the skin rather than just staining the surface.
I've used curing salts before and expect a little surface staining, but I've never seen anything like this.
My questions are:
Has anyone else seen curing salt dye penetrate pork rind this aggressively?
Is this simply an unusually strong food dye, or would this make you question the product itself?
Would you be comfortable eating the bacon if everything else (smell, texture, cure) seems normal?
I've attached photos of both the curing salt and the finished pork.
Thanks :)
