Why Great Value Shredded Mozzarella Is Pasteurized
The pasteurization of dairy products, including cheese, is a critical step in modern food manufacturing. For a widely distributed product like Great Value shredded mozzarella, ensuring a consistent and safe product is paramount. The process involves heating milk to a specific temperature for a set amount of time to destroy any potentially harmful pathogens, such as Listeria, E. coli, and Salmonella.
By using pasteurized milk, Walmart's Great Value brand ensures that its cheese is safe for the general population to consume. This includes groups who are particularly vulnerable to foodborne illnesses, such as pregnant women and those with compromised immune systems. For manufacturers operating on a large scale, pasteurization also provides a more predictable and stable starting point for cheese production, leading to greater product uniformity. While artisanal cheeses might sometimes use unpasteurized milk, strict aging requirements are necessary for their safety, which is not feasible for a standard, mass-produced product like shredded mozzarella.
The Pasteurization Process in Commercial Cheese
Commercial cheesemakers typically use the High-Temperature Short-Time (HTST) method of pasteurization.
- The milk is heated to at least 161.5°F (72°C) for a minimum of 15 seconds.
- This process is highly effective at eliminating pathogens while minimally affecting the milk's flavor and nutritional value.
- After pasteurization, the milk is quickly cooled before the cheesemaking process continues with the addition of starter cultures and enzymes.
- For products sold in the United States, any cheese made with raw milk must be aged for at least 60 days to kill off bacteria, but pasteurization is the more common and faster method for cheeses like mozzarella.
Great Value Shredded Mozzarella Ingredients
An examination of the ingredient list on Great Value shredded mozzarella packaging provides definitive proof of its pasteurization. The ingredients are clearly listed, demonstrating a commitment to transparency and consumer safety. This typically includes:
- Pasteurized Part-Skim Milk: This is the base ingredient, explicitly confirming the pasteurization process.
- Cheese Culture: Beneficial bacteria added to the milk to create the flavor and texture of mozzarella.
- Salt: Used for flavor and as a preservative.
- Enzymes: These are often microbial enzymes that help with the coagulation and curdling process.
- Anti-caking Agents: Ingredients like powdered cellulose or potato starch are added to prevent the shredded cheese from clumping together in the bag.
- Natamycin: A natural mold inhibitor used to extend shelf life.
Is Pasteurized Cheese Better than Raw Milk Cheese?
Whether pasteurized cheese is 'better' than raw milk cheese depends on consumer priorities, but it's universally considered safer. Here is a comparison of key factors:
| Feature | Pasteurized Cheese | Raw Milk Cheese | 
|---|---|---|
| Food Safety | Excellent; heat treatment eliminates harmful bacteria, making it safe for all populations, including pregnant women and children. | Variable; potential for harmful bacteria, especially in fresh or soft varieties. Requires strict hygiene and, in the U.S., a minimum 60-day aging period for safety. | 
| Flavor | Consistent and predictable. Heat can sometimes reduce the complexity of flavor in favor of a milder, more uniform taste. | Often more complex and dynamic due to naturally occurring enzymes and microflora. Flavor can vary depending on the season and diet of the cows. | 
| Availability | Extremely widespread; found in virtually all supermarkets and grocery stores due to mass production and extended shelf life. | Niche market; typically found in specialty cheese shops, farmer's markets, or artisanal stores. Less common in mainstream grocery chains. | 
| Shelf Life | Generally longer due to the elimination of a wider range of microorganisms. | Typically shorter and more sensitive to spoilage if not aged properly. | 
Handling and Storage of Shredded Mozzarella
Even with pasteurization, proper handling and storage of shredded mozzarella are essential to prevent contamination and maintain freshness. Bacteria can be introduced after the pasteurization process, a phenomenon known as secondary contamination.
Tips for safe handling:
- Check Packaging: Before purchasing, ensure the bag is sealed and not damaged.
- Refrigerate Immediately: Once home, store the cheese in the refrigerator at or below 40°F (4°C).
- Seal Tightly: After opening, reseal the bag completely to prevent moisture loss and exposure to air, which can encourage mold growth.
- Use by Date: Adhere to the 'best by' or 'use by' date printed on the package for optimal freshness.
- Wash Hands: Always wash your hands before and after handling the cheese to prevent cross-contamination from other foods.
The Importance of Label Reading
For consumers with specific dietary concerns, such as pregnant women or those avoiding certain additives, reading the ingredient label is crucial. For example, while the milk is pasteurized, some people may wish to know about the anti-caking agents or natural mold inhibitors used. The Great Value label clearly lists these ingredients, allowing for informed choices. For those with lactose intolerance, the pasteurization process does not remove lactose, but some hard, aged cheeses may contain less lactose due to the aging process.
Conclusion
Yes, Great Value shredded mozzarella cheese is definitively pasteurized. The milk used in its production is heated to eliminate harmful bacteria, a standard and safe practice for the vast majority of commercially available shredded cheeses in the United States. This provides consumers with a reliable, safe, and consistent product for all their cooking needs. By understanding that pasteurization is a food safety standard for this type of product, you can confidently use Great Value mozzarella in everything from pizzas to pasta dishes. Always remember to read the ingredient label to stay informed about what you're eating and practice safe food handling once the package is open.
