Green coloring on smoke ring

[Torc]

Day two of the smoked pork loin and was heating it up and noticed a greenish hue in the smoke ring.

Thoughts?

No idea if it's the cause, but nitrates and possibly nitrites (i cant remember) cause the sometimes shiny, rainbow or green effect on meat. burning wood releases nitrates, giving it that smoke ring.

Could be the color of the fat cap

From the USDA...JJ

Sliced cooked beef or lunchmeat can have an iridescent color. Meat contains iron, fat, and many other compounds. When light hits a slice of meat, it splits into colors like a rainbow. There are also various pigments in meat compounds which can give it an iridescent or greenish cast when exposed to heat and processing.Jul 17, 2019
