What is the best way to preserve turkey feet? I have always injected them with a product i got from Wasco called . Epo-Thin Set Injectable. Only to find out years down the road it has no preservative that i know in it. However none of the feet i have injected have gone bad, smelled, rotted, etc.

I see on Wasco's website they have another product called KNoblachs bird feet injection. Its description is "A safe preservative for injecting into the feet and wings of birds, feet of small game, and velvet antlers to reduce shrinkage. No offensive odors. Inject periodically while the mount is drying for best results."
I was wondering if anybody else had used this product or what everybody else does to preserve the feet since i know there is meat in there.
