Can you still eat persimmons if they turn black?

If the persimmons are only black spots on the skin, they are edible. If the flesh is black over a large area, it means that a large number of bacteria have grown inside the persimmons and they have begun to deteriorate and rot. They can no longer be eaten. For daily storage, persimmons can be placed in a ventilated and cool environment, or they can be refrigerated at 7 to 13 degrees.

1. As appropriate

Persimmons contain tannic acid, and they will turn black if they are exposed to air or iron for a long time. If the persimmon turns black with only small black spots on the skin, you can still eat it. However, if the flesh of the persimmon turns black over a large area, it means that a large number of bacteria have grown inside the persimmon, and it has begun to deteriorate and rot, and it can no longer be eaten.

2. Store at room temperature

Fresh persimmons can be stored at room temperature. When storing, choose a cool and ventilated environment to prevent the ethylene emitted by persimmons from accumulating in the air and accelerating the ripening and rotting of persimmons. In addition, placing persimmons in a ventilated place can also remove odors in the room. Generally, they can be stored for about 2 to 3 days.

3. Store in a refrigerator

If you want to extend the storage time of fresh persimmons, you can put them in the refrigerator. Persimmons stored in the refrigerator do not need to be washed, and the fruit powder on the surface of the persimmons can be retained. Then put the persimmons in a paper bag or a fresh-keeping bag, poke a few small holes in the bag, and finally put it in the refrigerator.

What are the black spots inside persimmons?

The black spots inside persimmons are due to the remnants of the seed coat. Some persimmon varieties have been artificially improved, so there will be black spots on the seed coat in the flesh. It may also be that when the persimmons are over-ripe, the tannins in them will be converted into sugar, making the flesh dark brown. It may also be that the black spots are formed by an oxidation reaction when the flesh comes into contact with oxygen.

1. Seed coat residue

The black spots inside persimmons may be the remains of the seed coat. Some persimmon varieties have been artificially modified to increase yield and taste, making the female flowers unable to conceive, leaving the seed coat in the persimmon flesh, resulting in small black spots in the middle of the persimmon.

2. Over-maturity

The black spots inside persimmons are due to over-ripening. Persimmons contain a certain amount of tannin, which will gradually convert into sugar after ripening. When persimmons are over-ripe, the color of the flesh inside will change, and many black spots will appear.

3. Oxidation reaction

The black spots on the surface of persimmons are due to an oxidation reaction. Persimmons contain a large amount of tannic acid and iron. After being cut, they will be exposed to the air and react with oxygen, causing the persimmons to turn brown, and small black spots will also appear.

How to store fresh persimmons for a longer time

Fresh persimmons can be stored in the refrigerator, in liquid or in the open air. You can put fresh persimmons in plastic bags or paper bags and refrigerate them in an environment of 7 to 15 degrees. You can especially choose persimmons with thicker peels and soak them in salt alum solution for storage. You can also store fresh persimmons on high shelves in a high and cool place.

1. Keep in refrigerator

Fresh persimmons can be stored longer by refrigeration. When storing, there is no need to wash the persimmons. First, pack the persimmons in plastic bags or paper bags to reduce the loss of water in the persimmons. Then, store them in a refrigerated environment at 7 to 15 degrees, which can be stored for a longer time.

2. Liquid storage

Fresh persimmons can be preserved by soaking in liquid. This method requires choosing persimmons with thicker peels, less water, and later maturity. First, mix water, salt, and alum in a ratio of 10:2:5 to make a storage solution, and then place the persimmons in it. This can preserve the persimmons for half a year.

3. Open-air storage

Fresh persimmons can be preserved by placing them on high racks that are high and shady, laying bamboo or corn stalks underneath the persimmons, and covering them with 15 cm thick straw. This can effectively preserve the freshness of the persimmons, but be sure to prevent them from frostbite during the winter.
