Cheese Cheesecake: How Long Does It Last?

The shelf life of a cheesecake depends on a variety of factors, such as the type of cake, preservatives used, packaging date, and storage method. It is important to note that cheesecakes should be refrigerated or frozen and not left on the counter. The cake should be consumed within 3 to 7 days of being baked or purchased. However, it can be frozen for up to 3 months. Leaving cheesecake at room temperature for more than 2 hours can cause bacteria to grow and spoil the cake.

Refrigerate or freeze to extend shelf life

To extend the shelf life of a cheesecake, it is important to refrigerate or freeze it.

Cheesecake should be stored in a refrigerator at 40°F or lower immediately after purchase and every use. It should be kept tightly covered to keep out moisture and other contaminants. Bacteria grows more rapidly in moist environments, so it is important to keep the cheesecake dry. Refrigerated cheesecake will last for about 1 week, but it should be noted that homemade cheesecake should not be kept for longer than 4–5 days.

For a long-term option, you can freeze cheesecake without a change to its quality. To freeze cheesecake, wrap it tightly with something freezer-safe, such as an airtight container, freezer bag, or a double layer of aluminum foil. Frozen cheesecake will maintain its best quality for about 2 to 3 months but will remain safe beyond that time.

Store-bought vs homemade shelf life

The shelf life of a cheesecake depends on a variety of factors, such as the type of cake, the preservatives used, the packaging date, and how it is stored. It is important to note that cheesecakes, unlike regular cakes, should be refrigerated or frozen. The rich, creamy texture of cheesecakes, which sets them apart from other cakes, is owed to dairy products, particularly cream cheese, and eggs—ingredients that are quite delicate and therefore reduce the shelf life of the dessert.

Store-bought cheesecakes tend to last longer than homemade ones, thanks to the use of commercial stabilizers and preservatives. Store-bought cheesecakes can be expected to last for about 3 to 7 days in the fridge, depending on the label instructions. If bought from a bakery, it will keep for 3 to 4 days, just like homemade cheesecake. The USDA recommends consuming homemade cheesecakes within 4 to 5 days, or less if the recipe calls for highly perishable ingredients.

Homemade cheesecakes have the shortest shelf life of all. Not only do they lack the preservatives of store-bought cheesecakes, but they have also experienced a great deal of temperature fluctuation, from the hot temperatures of the oven to cooling on the countertop to chilling in the fridge. This variation in temperature makes homemade cheesecakes more prone to spoilage.

Regardless of whether it is store-bought or homemade, it is important to note that unrefrigerated cheesecake left out for more than two hours can be unsafe to eat. Cheesecakes should be stored in airtight containers or wrapped in aluminium foil or plastic wrap to prevent them from drying out or absorbing odours from the fridge. For long-term storage, cheesecakes can be frozen without a change to their quality.

Freezing tips

Firstly, it is important to note that freezing cheesecake is a great option for keeping it fresh. It can be frozen whole or in slices, and it is best to freeze it as soon as it is fully set and chilled.

Before freezing, allow your cheesecake to cool to room temperature and then chill in the fridge until set. For baked cheesecakes, this will be until it reaches room temperature, and then it should be chilled in the fridge. For no-bake cheesecakes, be sure to chill them long enough to set before freezing.

When freezing a whole cheesecake, you can leave it in the springform pan, or remove the sides and place the cheesecake on a freezer-safe cardboard round or plate. Wrap the cheesecake tightly in at least two layers of plastic wrap, pressing the wrap close to the surface to keep out as much air as possible. Then, add a layer of heavy-duty aluminium foil.

If freezing slices, wrap each slice tightly in plastic wrap and then foil. Alternatively, you can freeze the whole cheesecake and then slice it once it is frozen. This will speed up the thawing process.

Cheesecake can be stored in the freezer for up to two months, but it is best to consume it within one month for optimal quality.

To defrost, leave the cheesecake in the refrigerator overnight, or at room temperature for two to four hours. If you are in a rush, you can defrost individual slices at room temperature, or even use the microwave in 30-second increments.

Once your cheesecake is defrosted, you can add your toppings. This is a great way to disguise any marks or lines left by the plastic wrap.

How to identify spoilage

Cheesecake is a rich dessert with a short shelf life, so it's easy to determine if it has gone bad. Here are some ways to identify spoilage:

Visible Signs of Spoilage

The appearance of a cheesecake can indicate whether it has spoiled. Fresh cheesecake usually has smooth, even edges and a moist texture. On the other hand, stale cake will have crusty and broken edges, and the cheese will feel and taste rubbery. The toppings may also develop an odd flavour and texture. For example, fresh fruit toppings can turn to leather. Additionally, the cheesecake may turn an unappealing yellow or develop grey spots, which are signs of bacterial activity.

Unpleasant Odour

If the cheesecake smells like stale dairy products or has an otherwise unpleasant odour, it has likely gone bad. This is another sign of bacterial activity, and consuming the cake at this point can make you sick.

Liquid Leakage

If the cheesecake starts to exude liquid, it is a sign that something has gone wrong. This is often due to the cake being left at room temperature for too long, allowing bacteria to grow and cause spoilage.

Mould Formation

Leaving the cheesecake uncovered in the fridge, especially if it has been left out at room temperature for too long, can cause mould to form. Even if the mould spores are not visible, it is best to discard the cake to avoid the risk of consuming harmful bacteria.

Exceeding Recommended Storage Time

Even when stored properly in the refrigerator, cheesecake has a limited shelf life. Store-bought cheesecake typically lasts 3 to 7 days, while homemade cheesecake should be consumed within 4 to 5 days. After this recommended storage time, it is best to discard the cheesecake, even if it appears and smells fine.

In summary, cheesecake spoilage can be identified through visible signs of deterioration, unpleasant odours, liquid leakage, mould formation, and exceeding the recommended storage time. To ensure food safety, it is important to inspect the cheesecake for any signs of spoilage and follow proper storage practices.

Health risks of eating spoilt cheesecake

Cheesecake is a delicious dessert, but it's important to be aware of the health risks associated with eating a spoilt cheesecake. Firstly, it's crucial to understand that cheesecake has a short shelf life due to its highly perishable ingredients, such as cream cheese, eggs, and dairy. These ingredients make cheesecake susceptible to bacterial growth, including listeria and salmonella, which can cause severe foodborne illnesses.

The shelf life of cheesecake varies depending on the type, preservatives used, packaging date, and storage conditions. When stored properly in the refrigerator at or below 40°F, cheesecake can last for 3 to 7 days for store-bought and 3 to 5 days for homemade varieties. However, if not stored properly, its shelf life decreases significantly, and the risk of spoilage increases.

Consuming spoilt cheesecake can lead to food poisoning, with symptoms including nausea, headache, stomach ache, diarrhoea, vomiting, fever, and cramps. These symptoms can last for several days and may require medical attention. Listeria infection, a particular concern with soft cheeses like cream cheese, can cause severe illness, especially in pregnant women, young children, older adults, and immunocompromised individuals. It can even lead to miscarriages in pregnant women.

To avoid the health risks associated with spoilt cheesecake, it is essential to practise safe food handling and storage. Cheesecake should be refrigerated or frozen promptly after purchase or preparation, and it should be tightly covered to prevent moisture and contaminant exposure. When serving, it is best to keep the cake chilled and follow food safety guidelines, such as not leaving perishable foods at room temperature for extended periods.

In summary, spoilt cheesecake can pose serious health risks, including foodborne illnesses and food poisoning. To enjoy cheesecake safely, it is crucial to follow proper storage and handling practices and consume it within its recommended shelf life.
