The white stuff on jerky is often tyrosine, an amino acid that can form crystals on the surface when the meat is dried. It's perfectly safe to eat. In some cases, it might also be salt that was used in the curing process, which can crystallize similarly. If the white substance appears fuzzy or is accompanied by an off smell, it could indicate mold, and the jerky should not be consumed.
