Understanding Pasteurization
Pasteurization is a heat treatment process that destroys harmful bacteria and other pathogens in food, significantly enhancing product safety and shelf life. This is especially crucial for dairy products to eliminate microorganisms like Listeria, which can cause serious foodborne illness. For consumers, particularly vulnerable groups like pregnant women, consuming pasteurized dairy is strongly recommended.
The Original Kraft Mac and Cheese Powder
The classic, iconic blue box relies on a packet of cheese sauce mix, not a block of cheese. This powder is the result of a multi-stage manufacturing process that involves pasteurization. The dairy ingredients, such as milk, whey, and actual cheese, are mixed and processed before being spray-dried to form the cheese powder. The heat from this processing step ensures that the final product is stable and free from harmful pathogens. According to the ingredients found on similar bulk powder products, cheese is listed as being made from "cultured pasteurized milk". Therefore, the powdered cheese sauce in the original boxed dinner is indeed made with pasteurized ingredients, and any bacterial risk is eliminated during its manufacturing.
The Liquid Cheese Sauce in Kraft Deluxe Varieties
Kraft offers a 'Deluxe' line of mac and cheese that features a pre-made liquid cheese sauce instead of a powder. A quick look at the ingredients list for these products confirms the use of pasteurized cheese. The ingredients specify "Pasteurized Process... Cheese," explicitly stating that the cheese has been treated with heat to kill bacteria. This provides the same level of food safety assurance as the original powdered version, but in a ready-made liquid form.
Why Processed Cheese is So Safe
Processed cheese, by its very nature, is a safer alternative to many fresh cheese varieties. The manufacturing of processed cheese involves heating and emulsifying a blend of cheeses and other dairy ingredients.
The Processing Steps
- Sourcing: Raw dairy ingredients are tested and transported to the facility.
- Pasteurization: The dairy liquids are pasteurized to kill bacteria.
- Processing: The cheese is heated and blended with other ingredients.
- Drying: For powdered varieties, the liquid slurry is spray-dried.
- Packaging: Final products are hermetically sealed, protecting against contamination.
This multi-step process effectively removes the risk associated with unpasteurized, or raw, milk, ensuring the final shelf-stable product is safe for consumption. The addition of emulsifying agents like sodium phosphate also helps to create the smooth, consistent texture that defines processed cheese.
Comparison: Pasteurized vs. Unpasteurized Cheese
| Feature | Pasteurized Cheese (Found in Kraft) | Unpasteurized/Raw Milk Cheese (Requires caution) |
|---|---|---|
| Processing | Heated to kill harmful bacteria. | Not heated to kill bacteria; relies on aging or fermentation. |
| Safety | High. Very low risk of foodborne illness like listeriosis. | Lower. Can potentially harbor harmful bacteria like Listeria and E.coli. |
| Source | Made with pasteurized milk. | Made with raw, untreated milk. |
| Target Audience | Suitable for general consumption, including vulnerable populations like pregnant women. | May be unsafe for pregnant women, young children, older adults, and those with weakened immune systems. |
| Example | Kraft Mac and Cheese, American cheese slices, cottage cheese. | Some imported soft cheeses (e.g., Brie, Camembert), artisanal cheeses. |
Is Kraft Mac and Cheese Safe During Pregnancy?
This is a common and important concern, and the answer is reassuring. Since Kraft mac and cheese products use pasteurized and processed cheese, they are considered safe to eat during pregnancy. The primary risk associated with cheese consumption during pregnancy comes from unpasteurized soft cheeses that can carry Listeria bacteria. Because Kraft products undergo rigorous pasteurization and processing, this risk is eliminated. As a general food safety rule during pregnancy, experts advise checking labels for the word "pasteurized" and avoiding unpasteurized products. Kraft's products meet this safety requirement.
Conclusion
In summary, every variety of Kraft mac and cheese, from the original boxed dinner with its cheese powder to the more decadent Deluxe versions with liquid sauce, utilizes pasteurized dairy ingredients. This heat treatment is a cornerstone of the manufacturing process, ensuring the elimination of harmful bacteria and providing a safe, shelf-stable product for consumers. For individuals concerned about food safety, including pregnant women, you can rest assured that this classic comfort food is a safe choice, thanks to its extensive processing and pasteurization.
