Understanding Pasteurized Milk in Cheesemaking
Pasteurization is a heat treatment process that involves heating milk to a specific temperature for a set time to kill disease-causing microbes. While raw milk advocates claim that the unheated milk offers more complex flavors, the pasteurization process provides a higher level of safety and consistency for large-scale and consumer cheese production. This process does not, however, mean that a cheese is devoid of flavor. Skilled cheesemakers use starter cultures to reintroduce beneficial bacteria that cultivate the desired texture and flavor profiles.
There are two main methods of pasteurization used in cheesemaking:
- High-Temperature Short-Time (HTST): This method involves heating the milk to at least 161°F (71.7°C) for 15 seconds. It is a rapid process often used for large-scale production.
- Low-Temperature Long-Time (LTLT): The milk is heated to a minimum of 145°F (63°C) and held for 30 minutes. This gentler process is often used by smaller creameries and is thought to preserve more flavor characteristics.
Popular Cheeses Made From Pasteurized Milk
A vast number of cheeses are produced with pasteurized milk, offering a safe option for all consumers, including those who are pregnant or immunocompromised. These cheeses span the full spectrum of texture and flavor, from soft and creamy to hard and sharp.
Soft and Semi-Soft Pasteurized Cheeses
- Mozzarella: A classic Italian cheese, commercial mozzarella is almost always made from pasteurized cow's milk and is a key ingredient on pizza and in Caprese salad.
- Feta: While traditionally from sheep or goat's milk, most commercially sold feta is made with pasteurized milk and boasts a salty, tangy profile.
- Cream Cheese: This soft, fresh cheese is a staple for bagels, dips, and desserts and is made from pasteurized milk and cream.
- Cottage Cheese: Known for its mild flavor and lumpy texture, cottage cheese is another fresh pasteurized option.
- Brie and Camembert: These iconic French cheeses can be made with either pasteurized or raw milk. In the U.S., commercial versions are typically pasteurized, but it's essential to check the label for safety.
- Ricotta: This Italian whey cheese is soft and creamy and made from the leftover whey of other cheese production, usually from pasteurized milk.
Hard and Semi-Hard Pasteurized Cheeses
- Cheddar: While some artisan cheddars are raw, the vast majority of widely available cheddars are made with pasteurized milk.
- Gouda: This Dutch cheese is known for its caramel-like flavor, and young versions are typically made with pasteurized cow's milk.
- Provolone: A semi-hard Italian cheese that is a popular addition to sandwiches and subs, and generally made with pasteurized milk.
- Swiss and Gruyère: Many varieties of Swiss-style cheeses, which are known for their distinctive holes, are made using pasteurized milk. As with other cheeses, checking the label is the safest approach.
- Parmesan: The vast majority of Parmesan-style cheeses available outside of Italy are made with pasteurized milk, unlike the traditional raw-milk Parmigiano-Reggiano.
Comparison of Common Pasteurized Cheeses
To help you decide, here is a comparison of some popular cheeses made from pasteurized milk.
| Cheese Type | Texture | Flavor Profile | Common Uses |
|---|---|---|---|
| Mozzarella | Soft, stringy | Mild, milky | Pizza, Caprese Salad, Lasagna |
| Feta | Crumbly, brined | Salty, tangy | Salads, stuffed peppers, pasta |
| Cream Cheese | Soft, smooth | Mild, slightly sweet | Bagels, cheesecakes, dips |
| Cheddar | Hard, firm | Mild to sharp | Sandwiches, macaroni and cheese, grilling |
| Gouda (young) | Semi-hard | Mild, nutty, caramel | Cheese boards, sandwiches, melting |
| Parmesan | Hard, grainy | Salty, nutty | Grating over pasta, salads, risottos |
The Verdict: Quality and Safety in Harmony
When selecting a cheese, the choice between pasteurized and unpasteurized is often a question of balancing flavor complexity with food safety, particularly for at-risk individuals. The wide availability and diversity of pasteurized cheeses mean that consumers never have to sacrifice flavor for peace of mind. The process of pasteurization has enabled large-scale cheese production to be consistent and safe while still delivering a delicious product for the everyday consumer. Artisan cheese makers can also produce incredible pasteurized cheeses, showcasing how the heat treatment doesn't inherently diminish quality but rather changes the profile of the final product. For those seeking safe and predictable cheese without compromising on taste, the abundance of pasteurized milk cheeses is a boon. The key is simply knowing what to look for and checking the label.

Conclusion
Understanding what cheese is made from pasteurized milk is straightforward once you know where to look. By checking product labels, you can confidently identify and enjoy a wide variety of soft, semi-soft, and hard cheeses that have undergone this important safety process. The majority of cheeses found in commercial grocery stores are made with pasteurized milk, making safe and delicious options highly accessible. The heat treatment ensures harmful bacteria are eliminated while still allowing for the creation of flavorful and high-quality cheese, from the creaminess of mozzarella to the sharpness of cheddar. The choice is yours, but for those prioritizing safety, especially for vulnerable populations, pasteurized cheese provides peace of mind without limiting your culinary options.
