Pre-packaged cheese is a convenient option for many, but some question the ingredients added to extend its shelf life. Preservatives and anti-caking agents are often used in pre-packaged cheese to maintain its texture and flavour. While these additives are generally safe for consumption, some argue that they affect the taste and performance of the cheese in recipes. The type of packaging material used for cheese is also important, with options including wax coatings, vacuum-sealed bags, aluminium foil, glass containers, and paper wraps, each offering different levels of protection against moisture, air, and contaminants. While pre-packaged cheese may not have the same flavour or texture as freshly grated cheese, it is a convenient and economical choice for many consumers.

Anti-caking agents like potato starch are added to pre-shredded cheese
Pre-shredded cheese is a convenient option for cooks, saving time and money. However, it often contains anti-caking agents like potato starch, which affect the texture and performance of the cheese. While these additives are tasteless and non-toxic, they can cause the cheese to resist melting and affect the overall mouthfeel.
Potato starch is a commercially available thickener with desiccating and anti-clumping properties. It is combined with cellulose, an ultra-fine powder derived from wood pulp, to prevent shreds of cheese from caking together. This combination allows manufacturers to use more anti-caking agents without compromising the colour and appearance of the cheese.
The addition of anti-caking agents is necessary due to the increased surface area of shredded cheese, which is more susceptible to mould, yeast, and fungal growth. Natamycin, an anti-mold agent, is typically sprayed on cheese shreds to address this issue. These additives also extend the shelf life of the product, making it more convenient and economical for consumers.
While the use of anti-caking agents may be advantageous for product longevity and cost-effectiveness, some consumers prefer freshly grated cheese for its purer flavour and better melting qualities. Ultimately, the choice between pre-shredded and freshly grated cheese depends on the specific requirements of the dish and the preferences of the cook.
To summarise, anti-caking agents like potato starch are added to pre-shredded cheese to prevent clumping and extend shelf life. While convenient, these additives may affect the performance and texture of the cheese, leading some consumers to opt for freshly grated alternatives.

Pre-packaged cheese uses preservatives to extend shelf life
Pre-packaged cheese often contains preservatives and anti-caking agents to extend its shelf life. While some people prefer to grate their own cheese to avoid these additives, they can be useful for preventing mould and extending the life of the product.
Cheese is a dairy product that is highly susceptible to spoilage. To extend the shelf life of cheese, manufacturers use a variety of preservatives and packaging materials. Preservatives such as natamycin, an anti-mold agent, are added to prevent the growth of mould, yeast, and fungi. Anti-caking agents such as potato starch and cellulose are also added to prevent the cheese shreds from clumping together and to improve their melting properties. These additives are tasteless and naturally occurring, and have been used in commercial food production for a long time.
The packaging materials used for cheese also play a crucial role in extending its shelf life. Wax coating, for example, has been a popular method of cheese packaging for centuries. By dipping cheese wheels or blocks in a layer of wax, producers create a protective barrier that keeps out air, moisture, and contaminants. This method is particularly effective for hard and semi-hard cheeses, as it prevents them from drying out while maintaining their flavour profile. Other packaging materials such as vacuum-sealed bags, aluminium foil, and modified atmosphere packaging (MAP) are also commonly used to control the environment inside the package, thereby preserving the flavour, texture, and freshness of the cheese.
The use of preservatives and packaging materials allows pre-packaged cheese to have a longer shelf life than fresh cheese. This makes it more convenient and cost-effective for consumers, as they can buy larger blocks of cheese that will last longer without spoilage. However, some people may prefer to grate their own cheese to avoid the additives in pre-packaged cheese, as these additives can affect the texture and melting properties of the cheese.
Overall, the use of preservatives and packaging materials in pre-packaged cheese is a trade-off between convenience and product quality. While it extends the shelf life of the product, it may also affect the taste and texture compared to freshly grated cheese.

Wax coatings are used to protect hard and semi-hard cheeses
Wax coatings are commonly used to protect hard and semi-hard cheeses from drying out and prevent exposure to external contaminants. This method involves dipping cheese wheels or blocks in wax, creating a protective barrier that effectively keeps out air, moisture, and other contaminants.
Hard cheeses, such as Parmesan and Cheddar, have a low moisture content and a firm texture. Wax coatings help safeguard these cheeses from further drying out while maintaining their flavour and texture. By creating a barrier against external elements, wax coatings ensure that hard cheeses remain protected during storage and transportation.
Semi-hard cheeses, such as Gouda and Emmental, have a slightly higher moisture content than hard cheeses. Wax coatings help maintain the shape and texture of these cheeses while preventing excessive moisture loss. The wax coating acts as a protective layer, allowing semi-hard cheeses to retain their desired consistency and quality.
Wax-coated cheeses also offer a unique and visually appealing appearance. The smooth, glossy surface of the wax coating makes the cheese stand out on store shelves, attracting consumers and enhancing its marketability.
In addition to wax coatings, other packaging materials are also used for hard and semi-hard cheeses. Vacuum-sealed bags, aluminium foil, and modified atmosphere packaging (MAP) are popular choices, providing effective barriers against air, moisture, and odours while extending the shelf life of the cheese.

Modified atmosphere packaging (MAP) is used for semi-hard cheeses like gouda
Modified atmosphere packaging (MAP) is a popular method used for semi-hard cheeses like Gouda and Emmental. These cheeses have a slightly higher moisture content than hard cheeses, and MAP helps maintain their shape and texture while preventing moisture loss.
MAP involves altering the atmosphere within the cheese package to prolong its freshness. The main gas used in MAP to inhibit the growth of spoilage bacteria and moulds is carbon dioxide (CO2). For semi-hard cheeses, a mixture of CO2 and nitrogen (N2) is used to ensure sensory quality and stability. MAP with CO2 concentrations between 50/50 and 80/20% CO2/N2 (v/v) is recommended for raw sheep-milk cheese wedges.
MAP is particularly effective for semi-hard cheeses as it allows the cheese to "breathe," developing more flavour and making it easier to separate individual pieces once the packet is opened. This is in contrast to vacuum packaging, which can cause undesirable compression and affect the paste appearance, flavour, and texture of the cheese.
MAP can significantly extend the shelf life of semi-hard cheeses. For example, a hard cheese like Cheddar packaged in high CO2 can have its shelf life extended from two to three weeks in air to up to ten weeks in MAP. Similarly, soft cheeses can last three times longer when stored under an appropriate atmosphere mixture of carbon dioxide and nitrogen.
Overall, MAP is a valuable strategy to preserve the quality and extend the shelf life of semi-hard cheeses like Gouda, making it a popular choice for cheese manufacturers and consumers alike.
