Potassium nitrate
Other names saltpeter, E252
Potassium nitrate: moderate in histamine. If you're sensitive to any of these, check it against your profile before eating.
Intolerances
- Histamine (+liberators / DAO inhibitors)Moderate
Potassium nitrate (E252) is saltpetre, the oldest curing salt there is - it predates the industrial nitrites by centuries and is still used in traditional dry cures. Same reasoning: the additive marks a long, slow process, and it is the process that produces the histamine.
