The shelf life of a plum cake largely depends on the ingredients used in its preparation. There are a number of factors that determine the shelf life of a plum cake including the dried fruits used in the cake mix, the liquid used to soak the dried fruits and the amount of liquid content present. Besides, the packaging and the sealing are also factors that influence shelf life. Similarly, we should also be careful how we place the cake after opening the packaging.
The Role of Soaking Liquids
One key factor to consider is the liquid used to soak the dried fruits that are added to the plum cake. If the dried fruits are soaked in rum, they contain alcohol that helps to preserve them. Therefore, the cake can be stored without getting spoiled for a longer period, about one month or even more, while maintaining its taste.
However, if liquids with high moisture content, such as orange juice, are used, the shelf life of the cake will be much shorter. But if the dried fruits are soaked in grape juice or orange juice for a month or even longer time, and the water content is completely removed by drying them properly, the shelf life of the cake can be increased. Normally, a homemade plum cake can be kept fresh at room temperature for about 5 to 7 days without getting spoiled.
The Role of Milk, Caramel and Preservatives
The shelf life can vary depending on the liquid used to soak the dried fruits and how thorough the process is. In most cases, reducing the moisture content of a plum cake tends to increase its shelf life. This is why milk is not used to make plum cakes. However, one can find cakes made with milk in the market as cakes prepared without milk tend to have a comparatively longer shelf life.
In reality, reducing the moisture content to the maximum possible extent determines the shelf life of a plum cake. Apart from moisture content, the amount of caramel used also plays a significant role. In addition, the amount of preservatives that might be present in the cake also has an impact on the shelf life.
Packaging Helps Keep Plum Cake Fresh
When delivered through online platforms, the cake’s packaging also has an effect on its shelf life. This is because improper packing, such as airtight packaging, can expose the cake to moisture and air. Hence, it is essential to use food-grade and moisture-proof packages. Materials directly contacting the cake should be food-grade.
In addition, the seal of the cake’s packaging should be protected. A broken seal would expose the cake to outside air, moisture, and unwanted particles that can compromise the cake’s quality and shelf life. Having excessive moisture within the packing can also promote mould growth. In the same way, the cake should be packed when fully cooled. Otherwise, moisture from the cake can cause condensation to form inside the packing. Taking these measures into consideration to ensure proper packing of the cake can provide no difficulty in buying a plum cake online.
Proper Storage of Plum Cake After Opening
Apart from the mentioned above, one should also pay attention to storing the cake after opening the package. Similar to the impact of ingredients, the liquid used for soaking of dried fruits, and packaging, the storage conditions also influence the shelf life of a product. However, if ensuring that the cake is protected from moisture and air, it will keep for more days. Firstly, it should be placed in a cool and dry area away from sunlight. Secondly, the remnants of a cake should be stored in an airtight container.
