A Closer Look at the Ingredients: Cellulose and Other Additives
The primary difference between shredded and block cheese lies in their ingredient lists. Block cheese is a pure dairy product, containing only milk, enzymes, and cultures, and sometimes salt. Shredded cheese, however, requires additional ingredients to maintain its texture and shelf life.
The Role of Anti-Caking Agents
To prevent the shreds from clumping together in the bag, manufacturers coat them with anti-caking agents. The most common additive is powdered cellulose, a plant-based fiber derived from wood pulp or cotton lint. Other agents can include potato starch or cornstarch. These powders absorb moisture, keeping the cheese shreds separate and dry. While cellulose is generally recognized as safe (GRAS) by the FDA and passes through the digestive system without absorption, some consumers prefer to avoid such additives. These additives can also slightly alter the flavor and inhibit a smooth, creamy melt, which is a major drawback for cooking applications like sauces or pizza.
Potential Health Implications and Nutritional Differences
From a strictly nutritional perspective, the differences between equivalent types of shredded and block cheese are often minimal, but some nuances exist. The trace amounts of starches in shredded cheese can contribute a small number of carbohydrates, a factor worth noting for individuals on a low-carb diet. While cellulose is a type of dietary fiber, the amount added to shredded cheese is so negligible that it doesn't significantly impact daily fiber intake.
For most people, the health consideration is less about the direct harm of the additives and more about the presence of unnecessary processing. Block cheese, being in a more natural state, appeals to those who prioritize whole, minimally processed foods. It also lacks the natural mold inhibitors like natamycin that are sometimes sprayed on pre-shredded varieties to extend shelf life.
Taste, Melt, and Culinary Performance
Beyond health and ingredients, the two forms of cheese offer very different culinary experiences.
Taste Profile
Because block cheese is fresher and lacks additives, it often has a fuller, richer flavor. The coating on pre-shredded cheese can create a flavor barrier, resulting in a drier, less flavorful bite when eaten cold, for instance in a salad.
Melting Quality
The most significant culinary difference is in the melt. The anti-caking agents that keep shredded cheese from clumping also prevent it from melting together into a smooth, cohesive sauce. This can result in a grainy or lumpy texture in dishes like macaroni and cheese or casseroles. Freshly grated block cheese, with its natural moisture and fats, melts into a luxurious, creamy pool, which is ideal for silky cheese sauces and that perfect pizza stretch.
Comparison Table: Shredded vs. Block Cheese
| Feature | Shredded Cheese | Block Cheese |
|---|---|---|
| Primary Additives | Cellulose, potato/cornstarch, natamycin | None |
| Convenience | High (ready-to-use) | Low (requires grating) |
| Cost | More expensive per ounce | Less expensive per ounce |
| Melt Quality | Can be grainy or clumpy | Smooth and creamy |
| Flavor | Can be milder or less fresh | Fuller, richer, and more intense |
| Shelf Life | Shorter once opened (surface area exposure) | Longer, especially when properly wrapped |
| Overall Health | Generally safe but contains extra processing | More natural and unprocessed |
The Cost of Convenience
Another factor influencing the choice between shredded and block cheese is cost. Pre-shredded cheese is almost always more expensive per ounce than block cheese. You are paying for the convenience of not having to grate it yourself. Over time, these small differences in price can add up, making block cheese a more economical choice, especially for those who consume cheese regularly.
Making the Right Choice for Your Kitchen
The final decision depends on your priorities: convenience versus culinary quality and minimal processing. For busy weeknights when you're just topping a taco, pre-shredded cheese is a convenient shortcut. For recipes where the cheese quality is paramount, like a homemade mac and cheese or a gourmet pizza, taking a few extra minutes to grate a block of cheese is worth the effort for superior results.
For the health-conscious consumer, block cheese is the clear winner due to its purity. However, if your primary concern is avoiding additives, it is possible to find some brands of pre-shredded cheese that use minimal or no anti-caking agents, though this is less common.
Ultimately, the choice is yours, but being aware of the key differences empowers you to make a more informed decision about what you put into your body. Some people, for example, freeze a large portion of freshly grated cheese to get the best of both worlds—freshness and convenience.

Conclusion: The Purest Choice Prevails
For those seeking the healthiest, most unprocessed option with the best culinary results, block cheese is the superior choice. Its lack of anti-caking agents and other additives means you get pure cheese, a richer flavor, and a better melt. While shredded cheese offers undeniable convenience, it comes with a trade-off in terms of freshness, flavor, and melt quality, and you pay extra for the privilege. Taking the time to grate your own cheese from a block not only saves you money but also ensures you are consuming a product in its most natural and delicious state.
How to Store Grated Cheese from a Block
To bridge the gap between convenience and quality, you can grate a block of cheese in advance. Store it in an airtight container or a freezer-safe bag. Adding a small amount of cornstarch can help prevent clumping. Freezing is also an excellent option for longer storage.
