Fruits generally have the following four characteristics:
1. Rich in juice;
2. Contain a high amount of soluble sugars, and many also contain volatile aromatic substances;
3. Usually eaten raw;
4. Can be eaten independently of three meals a day.
The better a food meets the above characteristics, the more it is perceived as a "fruit." For example, although bananas do not contain much juice, their flesh is rich in soluble sugars and volatile aromatic substances mainly composed of isoamyl acetate (commonly known as banana oil), are usually eaten raw, and can be eaten independently of three meals, so bananas are fruits. Another example is the tomato, although it is rich in juice and contains soluble sugars, it is not traditionally eaten raw very often, nor is it often eaten independently of three meals, so some people do not consider it a fruit; however, small-fruit varieties of tomatoes like cherry tomatoes are specifically for eating raw and are often eaten independently of three meals, so cherry tomatoes are generally considered fruits.
