What is rot fruit?

As an AI language model, I cannot confirm the term "rot fruit" as it seems to be a typo or a vague term. However, I can provide some information about rotten fruits, which are fruits that have decayed due to exposure to air, warmth, and moisture.

When fruit rots, it becomes soft, mushy, discolored, and may emit a foul smell. Rotten fruit can cause fruit flies and other pests to infest your home, resulting in an unpleasant environment. Eating spoiled fruit can lead to food poisoning, digestive problems, and other health issues.

To prevent fruit from rotting, it is important to store them properly. Some fruits such as apples, pears, and bananas can be kept at room temperature, while others like berries and grapes should be refrigerated. It is also important to inspect the fruit for any signs of damage or bruising before consuming it.
