Understanding the Spectrum of Cheese Processing
Not all cheese is created equal. Understanding the differences in processing helps consumers make informed choices. The term "processed cheese" has specific regulations, and many products commonly called cheese are, in fact, "cheese food" or "cheese product," which contain more additives. Natural cheeses adhere to a simpler tradition, retaining more natural character and nutritional value.
The Defining Characteristics of Natural Cheese
Natural cheese uses a minimal number of ingredients: milk, salt, a starter culture, and a coagulant like rennet. The entire process involves curdling the milk, separating the curds and whey, and then aging or ripening the cheese. This results in a product with a complex flavor profile and texture that varies by type. For instance, hard, aged cheeses develop a sharper flavor, while fresh cheeses remain mild and soft. The ingredient list is typically short and recognizable, free from emulsifying salts, artificial flavors, and preservatives common in highly processed versions.
Common Examples of Minimally Processed Cheeses
A wide variety of popular cheeses fall into the minimally processed or natural category. These can generally be purchased in blocks and often display an authentic, nuanced texture and flavor profile.
- Cheddar: Authentic cheddar is pressed and aged, resulting in a firm texture and a flavor that sharpens over time. To avoid highly processed versions, look for block cheddar and shred it yourself, as pre-shredded varieties often contain anti-caking agents.
- Mozzarella: Fresh mozzarella, sold as small balls (bocconcini) in water or brine, is a stretched-curd cheese with a mild flavor. Low-moisture block mozzarella is also minimally processed, though some commercial versions can have additives.
- Feta: Traditional Greek feta is made from sheep's or goat's milk and cured in brine, giving it a salty, tangy taste and a crumbly texture. European Union regulations mandate strict production methods for authentic Greek feta.
- Swiss/Emmental: Authentic Swiss-style cheeses like Emmental are natural products with no added preservatives, colors, or flavors. The characteristic holes form naturally from gases produced by bacteria during maturation.
- Parmesan: True Parmesan (Parmigiano-Reggiano) is a hard, aged cheese with a granular texture and complex nutty flavor. Its long aging process involves very few ingredients.
- Goat Cheese: Many varieties of chevre are minimally processed, made by simply adding acid and cultures to goat's milk to create a soft, tangy cheese.
The Difference Between Natural and Processed Cheese
The fundamental difference lies in the ingredients and manufacturing steps. Processed cheese is designed for uniformity, meltability, and a long shelf life. This is achieved by combining natural cheese with emulsifying salts and other additives.
| Feature | Natural Cheese | Processed Cheese | 
|---|---|---|
| Ingredients | Milk, salt, culture, rennet | Natural cheese, emulsifying salts, stabilizers, water, artificial flavorings, and colorings | 
| Manufacturing | Milk is curdled, separated from whey, and aged for flavor and texture | Natural cheese is shredded, melted with emulsifying salts and additives, and reformed | 
| Texture | Varies by type; can be dense, grainy, or creamy depending on the aging | Uniformly soft, smooth, and creamy; melts easily and consistently | 
| Flavor | Complex, diverse, and nuanced; develops and changes over time | Uniform and mild; often has a salty or tangy taste | 
| Nutritional Profile | Higher in protein, fats, and nutrients; fewer additives | Higher in sodium; contains additives like stabilizers and emulsifiers | 
| Common Forms | Blocks, wheels, and crumbles | Individually wrapped slices, spreads, or blocks of "cheese product" | 
How to Find Minimally Processed Cheese at the Store
Navigating the dairy aisle requires a discerning eye. Here are some strategies to help you choose the least processed options:
- Read the Ingredients List: Look for a short list of simple, recognizable ingredients. The fewer the items, the better. Avoid products with ingredients like sodium phosphate, sodium citrate, or other emulsifying agents.
- Buy Blocks Over Pre-Shredded: Pre-shredded cheeses often contain anti-caking agents like cellulose to prevent clumping. Buying cheese in a block and grating it yourself is the best way to avoid these extra ingredients.
- Inspect the Packaging: Natural cheese is often sold in solid blocks or wheels, while processed cheese is frequently found in individually wrapped slices, tubes, or plastic jars.
- Look for Designations: Certain geographical protection labels, like Protected Designation of Origin (PDO) for cheeses such as Parmigiano-Reggiano and Greek Feta, guarantee that the cheese was made using traditional methods.
- Buy from a Cheesemonger: Specialized cheese shops or deli counters are more likely to carry artisanal and small-batch cheeses that adhere to traditional, less-processed production methods.
Conclusion: Making Informed Cheese Choices
Choosing minimally processed cheese involves paying attention to the product's ingredient list, form, and production method. While all cheese production involves some level of processing, the term "highly processed" generally refers to products altered with extensive additives to create specific properties like a consistent melt or an extended shelf life. By opting for traditional, block-style natural cheeses like cheddar, mozzarella, feta, and Swiss, consumers can enjoy a product closer to its natural state, with a richer flavor and fewer unwanted extras. Reading labels and understanding the difference between a real cheese block and a processed cheese product is the key to making healthier and more delicious choices for your table.
