Shredded cheese is a convenient option for easy meals, but it has a shorter shelf life than block cheese. This is due to a larger surface area that allows bacteria to grow more quickly and the addition of anti-caking agents, which can affect the taste and melting ability of the cheese. To extend the shelf life of shredded cheese, it is recommended to store it in the coldest part of the fridge, typically the middle or top shelf, and to use a porous wrapping to prevent it from drying out. Additionally, freezing shredded cheese can increase its longevity by several months, although this may impact its melting ability and texture. It's important to inspect shredded cheese for any signs of spoilage, such as mold, odour, or discolouration, before consumption.

Shredded cheese is coated in cellulose to prevent sticking
Shredded cheese is often coated in cellulose, a natural structural compound, to prevent the cheese shreds from sticking together. This additive is commonly used in food products and is generally recognized as safe to consume by the Food and Drug Administration. In fact, cellulose is naturally found in many fruits, vegetables, grains, and nuts.
The cellulose coating on shredded cheese serves as an anti-caking agent, preventing the cheese from clumping inside the packaging. This helps to extend the shelf life of the product by inhibiting mold growth. It also acts as a thickening agent and can be used to replace fat and increase fiber content in food products.
While cellulose is considered safe for consumption, some people may prefer to avoid it due to its potential impact on the texture and melting properties of the cheese. The additive can affect the consistency of dishes, particularly those that rely on creamy, stringy cheese, like macaroni and cheese.
Additionally, some consumers may be hesitant to purchase shredded cheese coated in cellulose due to viral claims that the additive is made from "wood shavings," "bark," or "sawdust." However, these claims have been refuted by registered dietitians, who emphasize the importance of obtaining information from credible, scientifically sound sources.
Overall, while the cellulose coating on shredded cheese can effectively prevent sticking and prolong shelf life, some consumers may opt to grate their own cheese to avoid the additive's potential impact on texture and taste.

Shredded cheese is more susceptible to mould because of its increased surface area
Shredded cheese is more susceptible to mould than block cheese due to its increased surface area. When cheese is grated, it exposes more of the product to the air, providing more entry points for bacteria and mould spores. This means shredded cheese is likely to go bad faster than a block of cheese of the same variety.
The increased surface area of shredded cheese also means that it loses moisture more quickly, which can lead to a drier product. To prevent this, shredded cheese is often coated in cellulose, derived from wood pulp, or powdered potato starch, to prevent clumping. However, this can affect the melting properties of the cheese, and some people prefer to grate their own cheese to avoid this issue.
In addition to the inherent qualities of shredded cheese that make it more prone to spoilage, the way it is packaged and stored can also impact its shelf life. Shredded cheese is often sold in bags, which can be punctured or torn, increasing the exposure to air and moisture. It is important to store shredded cheese in a sealed container in the fridge to maintain its quality and prolong its shelf life.
Despite its increased susceptibility to mould, shredded cheese can still be safely consumed past its expiration date if it shows no signs of spoilage, such as mould, off odours, or discolouration. However, it is essential to exercise caution and use one's best judgment when consuming any food product past its expiration date.
To maximise the shelf life of shredded cheese, it is recommended to store it in the coldest part of the fridge, typically the middle or bottom shelves, and to use it promptly after opening. Additionally, freezing shredded cheese can extend its shelf life by several months, although this may affect its melting properties and texture.

Shredded cheese has a shorter shelf life than block cheese
Secondly, shredding the cheese increases the surface area exposed to air and bacteria, accelerating spoilage. The increased surface area also means that shredded cheese dries out more quickly than block cheese, which can affect both the taste and texture of the product.
Thirdly, pre-shredded cheese is often packaged in large bags, which can be punctured or torn more easily than the wax or paper wrapping typically used for block cheese. If the packaging is compromised, the cheese is more likely to be exposed to air and moisture, which can cause it to spoil more rapidly.
Finally, shredded cheese is often made from softer cheeses, such as mozzarella, which have a shorter shelf life than harder cheeses. Soft cheeses tend to spoil more quickly because they contain more moisture, providing an ideal environment for bacterial growth. Therefore, it is important to be aware of the shorter shelf life of shredded cheese and to use it promptly after purchase to ensure optimal taste and safety.

Shredded cheese can be frozen to extend its shelf life
When freezing shredded cheese, it is recommended to trim the cheese into a uniform shape and reduce as much contact with oxygen as possible during the freezing process. This can be done by using a vacuum sealer, which eliminates contact with surrounding air, allowing the cheese to be frozen for the longest time. If a vacuum sealer is not available, parchment paper followed by aluminum foil can be used. The parchment paper creates a barrier for the cheese, while the foil keeps everything in place.
It is also important to note that not all cheeses are suitable for freezing. Softer cheeses, for example, are not ideal for freezing due to their higher moisture content, which can result in more ice crystals forming and damaging the structure of the cheese. Cheeses that are best suited for freezing are semi-firm to firm blocks with no rind and are intended to be melted, such as cheddar, Jack, Colby, mozzarella, and provolone.
When thawing frozen shredded cheese, it is recommended to thaw it in the refrigerator for seven to eight hours per pound. It is important to note that previously frozen and thawed cheese should not be refrozen. Frozen shredded cheese will maintain its best quality for about eight months but will remain safe beyond that timeframe if constantly frozen at 0°F.

Shredded cheese is more convenient than block cheese
Another advantage of shredded cheese is its ability to be stored in the freezer, extending its shelf life. Freezing shredded cheese can help to maintain its quality and freshness for longer periods. This is particularly useful for those who may not consume cheese regularly or who wish to purchase cheese in larger quantities. By freezing shredded cheese, individuals can also take advantage of sales and discounts, reducing the overall cost of purchasing cheese.
Furthermore, shredded cheese is often favoured for its ability to be easily incorporated into various dishes. It can be sprinkled on top of meals, such as chilli or nachos, providing a quick and convenient way to add flavour and texture. Shredded cheese is also commonly used in recipes that call for melted cheese, such as macaroni and cheese, chicken parmesan, or grilled cheese sandwiches. Its shredded form allows for even distribution and faster melting compared to block cheese.
While block cheese has its advantages, such as potentially lower cost and longer shelf life, shredded cheese offers enhanced convenience and versatility. It eliminates the need for grating, making it a time-saving option for busy individuals and those seeking convenience in meal preparation. The ability to freeze shredded cheese also adds to its convenience, ensuring that consumers can maintain its freshness and avoid waste.

Frequently asked questions
Shredded cheese often has anti-caking additives such as cellulose, sawdust, or potato starch, which can cause it to go bad faster. Additionally, shredding increases the surface area exposed to oxygen, accelerating spoilage.
Soft shredded cheese like cheddar and mozzarella will only be good for one to two weeks after opening. Hard shredded cheeses like parmesan and Swiss should be eaten within a month of opening.
Look for any off odors, discoloring, or spots of mold on the shredded cheese. If the cheese has any of these signs, it has likely spoiled and should not be eaten.
To prevent shredded cheese from going bad, store it in a sealed bag or container in the fridge at a temperature below 40°F (4°C). You can also freeze shredded cheese to extend its shelf life, but this may affect its melting properties.
