Cheese and bread are two food items with varying shelf lives. While bread expires quickly, cheese can last for much longer, depending on the type and how it is stored. Soft cheeses, such as ricotta, feta, and mozzarella, have a high moisture content, making them more perishable and typically lasting about a week in the fridge. On the other hand, hard cheeses like Cheddar, Parmesan, and Gouda have a longer fridge life, ranging from three to four weeks, as they contain less moisture and are less prone to bacterial spoilage. Proper storage is crucial to extending the life of cheese; it should be wrapped in porous materials like wax or parchment paper to prevent drying out while allowing the cheese to breathe. Freezing is not recommended for soft cheeses, but harder varieties can be frozen for up to six months. Bread, on the other hand, usually contains preservatives, which contribute to its shorter shelf life compared to cheese.

Bread contains preservatives, cheese has salt and other preservatives
The shelf life of bread and cheese is influenced by a variety of factors, including preservatives, salt content, and storage methods. Bread typically contains preservatives, while cheese has a higher salt content and may also contain preservatives, which contribute to their respective shelf lives.
Bread is a staple food with a relatively short shelf life, largely due to its susceptibility to mould and microbial spoilage. To extend its shelf life, various preservatives are commonly used in bread-making. These preservatives can include chemical compounds such as sodium sulphite, potassium sulphite, sodium metabisulphite, and potassium metabisulphite. These sulphite compounds inhibit microbial growth and act as antioxidants, preventing the oxidation of fats and lipids in the bread, which keeps it fresher for longer. However, these preservatives have come under scrutiny for potentially causing allergic reactions and respiratory issues in sensitive individuals, particularly those with asthma. As a result, some bakers have turned to natural preservatives, such as raisin paste, raisin water, cherry laurel leaf extracts, sourdough and pea flour hydrolysate, and garlic extract, which have shown promising results in inhibiting mould growth.
On the other hand, cheese is known for its longer shelf life compared to bread. While cheese naturally contains salt, which acts as a preservative, it may also contain additional preservatives. The salt content in cheese helps to inhibit bacterial growth, thus slowing down the spoilage process. Different types of cheese have varying shelf lives, with hard cheeses lasting longer than soft cheeses due to their lower moisture content, which makes them less prone to bacterial growth.
The presence of preservatives and salt contributes to the slower spoilage of cheese compared to bread. However, it is important to note that the specific storage conditions and handling practices can also significantly impact the shelf life of both products. Proper storage methods, such as refrigeration and appropriate wrapping, are crucial for maintaining the quality and safety of both bread and cheese.
In summary, the combination of preservatives and salt in cheese contributes to its slower spoilage compared to bread, which primarily relies on preservatives to extend its shelf life. However, proper storage and handling practices remain essential for maximizing the shelf life of both products.

Cheese is contaminated by dirty hands or improper storage
Cheese is a food product that is susceptible to contamination from dirty hands or improper storage. To prevent cheese from spoiling, it is important to practice good hygiene and follow proper storage procedures.
Cheese can be contaminated by dirty hands, which can introduce harmful bacteria or other microbes to the surface of the cheese. Even after washing hands, some bacteria may remain, which can cause the cheese to spoil. To prevent this, it is recommended to wear food preparation gloves or ensure that a barrier, such as plastic wrap, is between hands and the cheese. Additionally, cross-contamination can occur when handling animals or other unclean surfaces and then touching cheese with the same unclean hands. This can be mitigated by practising good hygiene and sanitizing any surfaces that come into contact with cheese.
Improper storage of cheese can also lead to contamination and spoilage. Cheese should be stored in the refrigerator to maintain its quality and safety. Leaving cheese unwrapped can lead to contamination as it is exposed to air, excess moisture, and other off-flavours from foods in the refrigerator. The American Cheese Society advises storing cheese in fresh wrapping, preferably in waxed or parchment paper, after it has been opened. This helps to prevent the cheese from drying out or picking up other flavours. For soft and semi-soft cheeses with a high moisture content, it is recommended to use a resealable plastic container or bag to protect them from excess moisture and off-flavours.
Different types of cheese have specific storage requirements. For example, blue cheese, which is already moldy, can be wrapped in plastic wrap or specialty paper and placed in the crisper drawer of the refrigerator, lasting between one to two months. Semi-hard cheeses, such as cheddar, Swiss, and Gruyere, can be wrapped in plastic wrap or specialty cheese paper and placed in the crisper drawer, lasting up to 7 to 10 days. Hard cheeses like Parmigiano-Reggiano and aged Gouda have longer shelf lives and can be stored in plastic wrap or wax paper. Fresh cheese, such as mozzarella or feta, should be left in its original packaging and the water should be changed every few days, lasting 7 to 10 days in the fridge.
By following proper hygiene practices and storing cheese correctly, contamination and spoilage can be minimized, ensuring that cheese remains safe to consume and enjoys a longer shelf life.

Soft cheeses are highly perishable, hard cheeses are less prone to spoilage
Soft cheeses, such as cottage cheese, cream cheese, and Brie, are highly perishable. This is due to their high moisture content, which creates an environment that promotes bacterial growth and spoilage. Soft cheeses have a moisture content ranging from 50% to 80%, which is significantly higher than that of hard cheeses. This makes them more susceptible to contamination and spoilage, resulting in a shorter shelf life.
Soft cheeses are also more delicate and creamy, often made from fresh curds that have not been pressed or aged. Their high moisture content contributes to a softer texture, as found in cheeses like Brie and fresh mozzarella. This higher moisture content provides more opportunities for bacteria to grow, making soft cheeses more perishable. Therefore, soft cheeses should be consumed within one to two weeks of opening to ensure optimal quality and safety.
On the other hand, hard cheeses like cheddar, Parmesan, and Gouda have a lower moisture content, typically ranging from 49% to 69%. This lower moisture content makes hard cheeses less prone to bacterial growth and spoilage, resulting in a longer shelf life. Properly stored hard cheeses can last anywhere from four weeks to six months in the fridge, with unopened blocks lasting even longer.
Additionally, hard cheeses are less susceptible to contamination due to their harder texture and lower moisture content. They can be left unrefrigerated for longer periods without posing a food safety risk, although their quality and taste may be impacted. However, it is important to note that all cheeses can be susceptible to spoilage if not stored properly, regardless of their variety.
To extend the shelf life of soft cheeses, proper storage is crucial. Soft cheeses should be stored in airtight containers or wrapped in specific papers to limit airflow and maintain moisture. On the other hand, hard cheeses benefit from being stored in breathable materials like parchment paper or cheesecloth to prevent drying out.

Cheese is mold, rind on Brie, blue cheese, etc. are all types of mold
It is a common misconception that cheese is mould. While some cheeses, like blue cheese, do contain mould, normal cheese is not mould. Instead, it is coagulated milk protein.
Mould is added to some cheeses for flavour, and it is common for moisture to attract mould. However, mould is not always involved in the cheese-making process. Yeast and bacteria play a role in fermenting sugars in curdled milk to produce different flavours.
Cheese can last a long time, especially when compared to bread and milk. This is because milk is a raw product, so it will expire much quicker than its processed counterpart, cheese. Bread, on the other hand, usually contains preservatives, which can make it last longer.
Cheese can be preserved for longer by wrapping it in wax, parchment, or cheese paper and storing it in the fridge. Soft cheeses tend to spoil more quickly than hard varieties as they contain more moisture and are therefore more prone to spoilage from bacteria. Hard, unopened cheeses can last up to 6 months in the fridge, while soft cheeses last about 1-2 weeks.

Cheddar dries out before it molds, Brie smells like ammonia when left too long
Cheese and bread are both susceptible to spoilage, but the rate at which they go bad can vary depending on several factors. Cheese, for instance, typically lasts longer than bread due to its lower moisture content and the presence of salt and preservatives. However, the behaviour of different cheeses when they go bad can vary.
Cheddar, a variety of hard cheese, tends to dry out before it moulds. This is because hard cheeses like Cheddar have a lower moisture content, which inhibits the growth of mould. When exposed to air, the moisture in the cheese evaporates, causing it to dry out.
On the other hand, soft cheeses like Brie are more susceptible to mould growth due to their higher moisture content. Brie is what is known as a "bloomy rind" cheese, which means that during its production, a mould culture is introduced that forms the white rind characteristic of this cheese variety. This mould culture feeds on the cheese proteins and, in the process, produces ammonia, resulting in a strong ammonia smell if the cheese is not properly stored.
If Brie is tightly wrapped in plastic and refrigerated without allowing it to breathe, the ammonia can become trapped, leading to a significant ammonia build-up. This is why it is common for consumers to notice a strong ammonia smell upon opening a store-bought Brie that has been tightly wrapped and refrigerated.
To prevent this, it is recommended to purchase Brie from a cheese shop where it is allowed to breathe, or to unwrap the cheese and let it air out before consumption. Additionally, proper storage practices, such as appropriate wrapping and temperature control, can help extend the shelf life of cheese and slow down the development of off-flavours and odours.
