Kunzler hot dogs and the use of sodium nitrite
When examining the ingredients for Kunzler's hot dogs, you will find sodium nitrite listed as a standard component in most of their cured franks. This additive serves a crucial purpose in the production of processed meats, acting as both a preservative and a color fixative. It is responsible for giving hot dogs and other cured products their characteristic pinkish color and preventing the growth of harmful bacteria, most notably Clostridium botulinum.
On the Kunzler website, product information pages for different types of hot dogs list sodium nitrite as one of the ingredients. This is true for their beef franks, chicken franks, turkey franks, and grill franks, which contain a blend of pork and beef. Sodium erythorbate is often listed alongside sodium nitrite, an antioxidant that helps prevent the formation of nitrosamines, which can occur when nitrates are heated.
What are nitrates and nitrites in food?
Nitrates and nitrites are simple compounds made of nitrogen and oxygen that are either naturally occurring or added to foods. Vegetables like spinach and beetroot are natural sources of nitrates. In the context of processed meats, however, they are usually added as sodium nitrite. Once in the body, nitrates can convert to nitrites. Both compounds can then form N-nitroso compounds (nitrosamines), particularly when cooked at high temperatures.
Are there Kunzler hot dogs without nitrates?
For consumers seeking to avoid added nitrites, it is essential to read ingredient labels carefully. Kunzler's website and marketing materials do not currently highlight a specific line of "uncured" or "nitrate-free" hot dogs. The term "uncured" in the meat industry typically means that no synthetic nitrates or nitrites have been added. Instead, natural sources like celery powder or celery juice are used, which contain naturally occurring nitrates that convert to nitrites during the curing process. Without specific product information indicating an uncured option from Kunzler, it's safest to assume their standard franks are cured with sodium nitrite.

Comparison of Kunzler franks with "uncured" options
| Feature | Kunzler Standard Franks | Common "Uncured" Hot Dogs | Curing Agent | Sodium Nitrite | Natural sources like celery powder | Regulatory Label | Cured | Uncured or 'no nitrates added' | Preservation Method | Synthetic sodium nitrite inhibits bacterial growth | Natural nitrates from vegetables inhibit bacterial growth | Flavor Profile | Consistent, classic frankfurter taste | Can have a slightly different, sometimes more herbal, taste | Color | Characteristic pink color | Consistent color, derived from natural nitrites | Availability | Widely available | Becoming more common but still a specialty item | Nitrosamine Risk | Mitigated by sodium erythorbate | Also forms nitrosamines, but depends on processing | Labeling Nuance | Clearly states sodium nitrite | 'Except for those naturally occurring in celery powder' | Cost | Generally standard price | Often slightly higher priced | Health Concern Perception | Higher public health concern | Perceived as healthier, though chemically similar process occurs |
Is it safe to eat Kunzler hot dogs?
For most people, the occasional consumption of Kunzler hot dogs is not a cause for concern. The addition of sodium erythorbate acts to reduce the formation of potentially harmful nitrosamines. The overall risk from nitrates and nitrites is complex and depends on many factors, including the type of meat, cooking method, and the presence of inhibiting agents like vitamin C. Authoritative health organizations, like the International Agency for Research on Cancer (IARC), have categorized processed meat as carcinogenic, though the risk is associated with overall consumption rather than any single hot dog. Consumers who are concerned should consider reducing their overall intake of processed meats, regardless of the brand or curing method.
Conclusion
Yes, Kunzler hot dogs do have nitrates, specifically in the form of sodium nitrite, as clearly indicated in the ingredients lists for their beef, chicken, pork, and turkey franks. Sodium nitrite is an industry-standard curing agent used to preserve the meat and fix its color. The brand does not advertise a line of "uncured" hot dogs. While Kunzler uses sodium erythorbate to mitigate the formation of nitrosamines, those with concerns about nitrates should consider alternative products labeled "uncured," which use naturally sourced nitrates, or reduce their overall processed meat consumption.
