Can cakes be eaten overnight at room temperature

Whether a cake can be eaten overnight at room temperature depends on the storage environment. Cake that has not spoiled and is sealed can usually be eaten, but there is a risk of microbial contamination. Cake stored at room temperature for a long time is prone to bacterial growth, especially in categories containing cream, dairy products, or fruits. In high temperature or humid environments during summer, the growth rate of microorganisms accelerates, and cakes may spoil within a few hours. If the room temperature is below 25 degrees Celsius and the cake seal is intact, some dry cakes such as pound cakes and sponge cakes can still be safely consumed overnight, but it is necessary to observe whether there is any odor, stickiness, or mold.

Categories containing perishable ingredients such as cream cakes and mousse have a higher risk of bacterial contamination, even if their appearance is normal. If the tools or hands are not strictly disinfected during the production process, the probability of contamination by pathogens such as Salmonella and Staphylococcus aureus increases significantly. People with diabetes, children and people with low immunity should avoid eating overnight cakes, which may cause gastroenteritis or food poisoning.

It is recommended to refrigerate the cake and consume it within 24 hours. Before consumption, check the texture and aroma. If it needs to be stored for a long time, it should be frozen. Although the taste slightly decreases after reheating, it is safer. In daily life, homemade cakes with compliant preservatives such as sodium dehydroacetate can be added, or the sugar and oil content can be reduced to delay spoilage. If discomfort symptoms such as abdominal pain and diarrhea occur, seek medical attention promptly.
