Nitrifiers are chemical compounds (nitrites and nitrates) that are added to cured meats and hams for several key reasons:
Preservation: They prevent the growth of dangerous bacteria, such as Clostridium botulinum (which causes botulism). botulism).
Characteristic color: Without them, the ham would have an unappealing grayish tone. Nitrites react with the myoglobin in the meat, giving it that intense red color.
Aroma and flavor: They contribute to the traditional flavor profile of cured ham.
Sugar in Ham: What Is It For?
Although ham is a salted product, many manufacturers add small amounts of sugar (dextrose, sucrose, or lactose) during the salting process. Its functions are:
Balancing the flavor: Mitigates excess salt and enhances umami nuances.
Controlled fermentation: In cured hams, it helps beneficial bacteria during maturation.
Juicier texture: Slightly retains moisture.
Is Added Sugar Dangerous?
In the amounts used (generally less than 1%), it does not pose a health risk. However, some consumers prefer to avoid it because:
- Low-carb diets (e.g., keto).
- More natural products (100% additive-free ham).
Controversies and Myths About Nitrites and Sugar
Myth 1: "Nitrites cause cancer"
- Reality: In high doses and with cooking at high temperatures (e.g., fried bacon), they can form **nitrosamines** (carcinogenic compounds).
-
In Iberian ham, the risk is minimal due to:
Low concentration regulated by law.
Lack of cooking.
Myth 2: "Sugar is a cheap filler"
Reality: It is used in minute quantities and for a technological purpose, not to reduce costs.

To choose a quality Iberian ham, check:
✅ Clear labeling:
- Ham without additives: It only contains pork, salt, and time.
- With additives: Look for "E-250", "E-252" (nitrifiers), or "dextrose" (sugar).
✅ Designation of Origin:
D.O. hams. (like Jabugo or Guijuelo) follow strict regulations regarding additives.
✅ Natural color and aroma:
