An overview of food preservation.
In the curing of meats like ham and bacon, nitrates and nitrites serve several critical functions:
- Safety: They are essential for inhibiting the growth of Clostridium botulinum, the bacterium responsible for botulism.12
- Color: They react with myoglobin to produce the characteristic pink or reddish color associated with cured meats.32
- Preservation: They help retard rancidity in meat products.3
While these additives are effective, their use is a subject of debate. Critics point to their potential carcinogenic activity and argue that modern refrigeration and sanitation may reduce the necessity for such chemicals. Conversely, industry representatives emphasize their role in maintaining the aesthetic appeal of products, noting that the natural color of uncured meat may be perceived as unappetizing by consumers. To mitigate risks, substances like sodium erythorbate or ascorbate are often added to improve color development and decrease potential health concerns associated with nitrite use.32
