The Nitrate Controversy: Cured vs. "Uncured"
For decades, meat companies have used nitrates and nitrites, chemical compounds made of nitrogen and oxygen, to cure and preserve meats. These additives serve several important functions, including inhibiting bacterial growth, preserving flavor, and stabilizing the red or pink color of the meat. Public awareness of the potential health risks associated with processed meats has increased the demand for alternatives without synthetic additives. This shift has led to the rise of products labeled "uncured."
This labeling, regulated by the USDA, can be misleading. "Uncured" means the meat wasn't preserved using synthetic nitrates and nitrites. Instead, manufacturers use natural sources like cultured celery juice or celery powder. A product cured with celery powder is still cured, but the use of natural ingredients allows it to be labeled "uncured" with a qualifying phrase like: "No nitrates or nitrites added except those naturally occurring in cultured celery juice". The body processes natural and synthetic nitrites similarly.
The Oscar Mayer Approach to Deli Meat Preservation
Oscar Mayer offers both traditional cured products and a line of "uncured" deli meats under its Deli Fresh brand. Their Smoked Uncured Ham, for example, states it has "No Nitrates Or Nitrites Added Except Those Naturally Occurring In Cultured Celery Juice". Other items, like their Deli Fresh Oven Roasted Turkey, make similar claims. Reading the fine print is essential. A "cured" label likely means synthetic nitrites, while an "uncured" label will specify the natural source.
The Role of Celery Powder in Uncured Meats
Celery powder is common in "uncured" products. Celery is naturally high in nitrates, which are converted to nitrites by fermentation and then used for curing. This process serves the same function as synthetic sodium nitrite. While synthetic additives are avoided, nitrites are still consumed.
Cured vs. "Uncured" Oscar Mayer Deli Meats Comparison
| Feature | Traditional Cured Oscar Mayer Deli Meat | Oscar Mayer "Uncured" Deli Meat |
|---|---|---|
| Preservation Method | Uses synthetic sodium nitrite or sodium nitrate. | Uses naturally occurring nitrites from sources like cultured celery juice. |
| Labeling | Labeled as "cured" or mentions specific chemical preservatives. | Labeled as "uncured" and includes a statement like "No Nitrates or Nitrites Added Except Those Naturally Occurring in Cultured Celery Juice". |
| Source of Nitrites | Lab-produced chemical compounds. | Natural vegetable sources, such as cultured celery powder or juice. |
| Taste Profile | Distinct salty, smoky, and preserved flavor often associated with cured meat. | Milder flavor profile, though can be enhanced with natural spices. |
| Appearance | Often has a more vibrant pink or red color due to the synthetic nitrites. | Coloration may be less uniform, reflecting the natural curing process. |
| Shelf Life | Longer shelf life due to the robust preservative action of synthetic nitrites. | Shorter shelf life due to reliance on natural, less concentrated preservatives. |
How to Identify the Nitrite Source
To determine the nitrite source in Oscar Mayer products:
- Check the front label: Look for "uncured".
- Read the ingredient list: For "uncured" products, look for "cultured celery juice," or similar phrasing. Cured meats list "sodium nitrite" or "sodium nitrate".
- Look for the USDA statement: "Uncured" products must have a disclaimer like "No nitrates or nitrites added except those naturally occurring in cultured celery juice".
Conclusion: What’s the Takeaway?
Some Oscar Mayer deli meats contain synthetic nitrates and nitrites (cured products), while others use natural nitrites from sources like celery juice ("uncured" products). "Uncured" means natural nitrites are used instead of synthetic ones, not that the product is nitrite-free. Consumers should carefully read labels to make informed choices.
