Pre-shredded cheese is a convenient option for busy home cooks, but it has a reputation for not melting properly. This is due to the anti-caking agents used to prevent the cheese from clumping together in the bag, such as potato starch, cellulose, and cornstarch. These additives create a drier texture and a barrier to flavour, resulting in cheese that does not melt uniformly and leaves an unappetizing, lumpy mouthfeel. To achieve a smooth and creamy melted cheese sauce, freshly grated cheese is the better option.

What You'll Learn

Pre-shredded cheese contains preservatives and anti-caking agents
Pre-shredded cheese is a convenient option for those who don't want to shred a block of cheese themselves. However, this convenience comes at the cost of optimal melting ability. Pre-shredded cheese contains preservatives and anti-caking agents to keep the shreds from clumping together in the bag. These additives include potato starch, cellulose, cornstarch, and natamycin. While these ingredients serve the important purpose of maintaining shelf stability, they also affect the melting properties of the cheese.
The anti-caking agents create a drier texture when the cheese is served cold and can act as a barrier to flavor. When heated, these agents prevent the cheese from melting uniformly into a smooth, creamy sauce. Instead, the cheese may remain separated and only partially melted, resulting in an unappetizing appearance and a lumpy mouthfeel.
The starches in these anti-caking agents repel moisture, which is necessary for proper melting. The starches coat each cheese grain, drawing in excess moisture and preventing stickiness. This results in cheese that does not melt together as well during cooking, leading to a globby or clumpy texture.
While pre-shredded cheese may be suitable for certain dishes where perfect melting is not required, such as topping a baked potato or mixing into a salad, it is not ideal for dishes that rely on a smooth and creamy cheese sauce. For these types of dishes, it is recommended to grate a block of cheese yourself to achieve the desired melting consistency.

These additives prevent clumping and sticking
Pre-shredded cheese is a convenient option for many home cooks. However, it is often criticised for its inability to melt properly. The reason behind this lies in the additives used to prevent clumping and sticking.
Pre-shredded cheese contains anti-caking agents, such as potato starch, cellulose, and powdered cellulose. These additives create a barrier on each cheese strand, repelling moisture and preventing stickiness. While these agents ensure the cheese stays shredded and separated in its packaging, they also hinder the melting process. The result is cheese that remains separated and only partially melted, with a lumpy texture.
Cornstarch is another commonly used additive in pre-shredded cheese. It is derived from high-carbohydrate foods and helps absorb excess moisture. However, cornstarch, like other anti-caking agents, can prevent the cheese from melting uniformly.
The presence of these additives means that pre-shredded cheese may not be suitable for dishes that require a smooth, creamy cheese sauce. Instead, it is recommended to buy block cheese and grate it yourself to achieve the desired meltiness in sauces and stovetop dishes.
While pre-shredded cheese may not be ideal for melting, it can still be a convenient option for quick snacks or dishes where perfect melting is not a requirement, such as topping a baked potato or mixing into a salad.

They also repel moisture, affecting the melting process
Pre-shredded cheese is a convenient option for cooks, but it has a reputation for not melting properly. The cheese contains additives like potato starch, cellulose, and cornstarch, which are anti-caking agents that prevent the shreds from clumping together in the bag. These additives are the reason pre-shredded cheese doesn't melt uniformly. They repel moisture, affecting the melting process.
Potato starch, cellulose, and cornstarch are all hydrophilic, meaning they attract water molecules. When these starches are added to pre-shredded cheese, they draw in moisture from the environment and the cheese itself, preventing stickiness and clumping. However, this also means that the cheese won't melt as easily when cooked. The starches coat each grain of cheese, creating a barrier that prevents the cheese from melting into a smooth, creamy sauce.
The anti-caking agents in pre-shredded cheese serve an important purpose in maintaining the shelf stability of the product. Without these additives, the cheese would clump together in its packaging, requiring consumers to grate it themselves. While these agents are necessary for convenience and product presentation, they do impact the melting ability of the cheese.
To achieve a smooth and creamy melted cheese sauce, it is recommended to grate a block of cheese yourself. Freshly grated cheese lacks the additives found in pre-shredded cheese, resulting in a smoother and less clumpy texture when melted. It is also important to melt cheese at a low temperature to retain moisture and fat content, which further contributes to a desirable melted cheese consistency.
While pre-shredded cheese may not be ideal for dishes that require a uniform melt, it can still be used in certain applications. For toppings or dishes where a perfect melt is not required, pre-shredded cheese can be a convenient option. However, for dishes like cheese sauces, fondues, or pizzas, freshly grated cheese will provide a superior melting experience.

Freshly grated cheese lacks additives, resulting in a smoother texture
Pre-shredded cheese is a convenient option for those who don't want to shred a block of cheese themselves. However, it is well-known for its inability to melt properly. This is due to the additives used to prevent the cheese from clumping together in its packaging. These additives create a barrier that affects the texture and flavour of the cheese, resulting in a drier texture and an unappetizing, lumpy mouthfeel when melted.
Freshly grated cheese, on the other hand, lacks these additives and preservatives, resulting in a smoother texture and a fresher, creamier taste. It is a healthier option with fewer additives. When used in cooking, it melts together more easily, resulting in a smoother, less clumpy dish.
The additives in pre-shredded cheese include cellulose, cornstarch, and potato starch, which are anti-caking agents that repel moisture. These additives are necessary to keep the cheese shredded and stable on store shelves, but they do affect the melting ability of the cheese.
To achieve a smooth and creamy cheese sauce, it is best to use freshly grated cheese with a higher moisture content and a lower melting point. Cheddar, Swiss, and Gruyère are popular choices for cheese sauces. When melting cheese, it is important to do so at a low temperature to prevent the cheese from burning and to stir frequently to ensure even melting.
While pre-shredded cheese may be convenient, it is not ideal for dishes that require a uniform, melted consistency. It is better suited for quick snacks, baked potatoes, and dishes where perfect melting is not required. For dishes that require a smooth and creamy cheese sauce, freshly grated cheese is the better option.

Freshly grated cheese is also cheaper and has a fresher taste
Pre-shredded cheese is a convenient option for those who don't want to shred a block of cheese themselves. However, it is important to note that the convenience comes at a cost. Firstly, pre-shredded cheese contains additives like potato starch, cellulose, and natamycin, which are anti-caking agents that prevent the cheese shreds from clumping together in the bag. These additives can affect the melting ability of the cheese, resulting in a lumpy and unappetizing texture when used in sauces or dishes that require a smooth, creamy melt.
On the other hand, freshly grated cheese is free from these additives and preservatives, resulting in a fresher and creamier taste. It is also cheaper to buy a block of cheese and grate it yourself than to purchase pre-shredded cheese, where you pay extra for the labour of shredding. By grating your own cheese, you also have access to a wider variety of cheese options beyond the limited selection typically offered in pre-shredded packages.
Freshly grated cheese is the best option for achieving a smooth and creamy melt in sauces and stovetop dishes. It lacks the additives found in pre-shredded cheese, resulting in a more natural flavour and a smoother texture. While pre-shredded cheese has its place in quick snacks or dishes where perfect melting is not required, freshly grated cheese is the superior choice for dishes that rely on a creamy, uniform melt.
Additionally, the process of melting freshly grated cheese is just as important as the type of cheese used. To achieve the best melt, it is recommended to use low heat and add the cheese slowly, stirring frequently to prevent burning and ensure even melting. This extra care and attention during the cooking process further contribute to the superior taste and texture of dishes made with freshly grated cheese.
In summary, freshly grated cheese is not only cheaper but also provides a fresher taste and a smoother, more natural texture in dishes that require melted cheese. While pre-shredded cheese has its conveniences, the additives and preservatives it contains can negatively impact the melting ability and overall flavour of the dish. For the best results in both taste and texture, taking the time to grate your own cheese and melting it with care is well worth the effort.
