The main reasons for the cold persimmon market are as follows:
1. Persimmons are easily infested with maggots. Some ripe persimmons will carry maggots. Even though they look perfectly healthy on the outside, they still carry maggots inside and consumers find it difficult to distinguish with the naked eye.
2. Persimmon are difficult to store. Supermarkets do not only pay attention to the purchase price, but also to the care customers need to take in storing fruit after they purchase it. Apples and pears can be kept for quite a long time compared to persimmons. Supermarkets therefore purchase persimmons that are not yet ripe, but these persimmons are quite tart. Customers need to store them at home until they are ripe and edible.
