What's wrong with persimmons?

The main reason why persimmons are said to cause safety problems is because they contain - ellagic acid. What exactly is ellagic acid?

Ellagic acid, also known as tannins, is the source of astringency in persimmons. Apart from persimmons, fruits like grapes, hawthorn, pomegranate and even the tea you drink are rich in ellagic acid.

Under certain conditions, ellagic acid can combine with proteins to form ellagic acid proteins, which are larger molecules and water-insoluble precipitates. When more stomach acid in the stomach, ellagic acid protein and food pectin, cellulose, etc., the persimmon skin, persimmon core bonded together, in the stomach quickly formed gastric stone, also known as gastric persimmon stone, and cause gastric discomfort.

So, does this mean that we can not eat persimmons?

Can you eat persimmons or not?

In fact, the ellagic acid in persimmons is not as scary as everyone fears.

First of all, different persimmons, ellagic acid content varies greatly.

Different persimmons have different levels of ellagic acid, generally between 0.4% and 4%, a difference of up to ten times. When the persimmon is not ripe, the ellagic acid content is higher, especially in the outer layer of the pulp - that is, near the skin of the persimmon, ellagic acid distribution is higher, but after ripening ellagic acid is very little. To determine whether a persimmon is high in ellagic acid, you can use the simplest method - the tongue. Generally, sweet persimmons have very little ellagic acid when ripe (less than 0.5%). So, if the persimmon is very astringent, it means the higher the ellagic acid content.

Secondly, persimmons sold in the market nowadays are basically low in ellagic acid.

Marketed . Commercialized persimmons have to go through a step of de-astringent treatment before they are sold on the market. After all, if the flavor is too astringent, consumers do not buy. As long as the de-astringent treatment, the content of ellagic acid is very low, do not worry too much about will lead to stones, you can rest assured to buy.

However, we need to remind you that if you go to some mountains to pick persimmons yourself, or buy some so-called home-grown persimmons, it is likely that they have not been de-astringent, try not to eat.

Overall, as long as the regular persimmons, ellagic acid content is generally not high, you can safely eat.
