What is the white frost on the persimmon? Can the white frost on the persimmon be eaten?

I remember when I was a child, every autumn and winter, every family in the village would make some persimmons and keep them for the Spring Festival. Looking at persimmons from a full of fresh fruit into a persimmon full of white frost, but when eating persimmons, do you notice what is the white frost on persimmons?

What is the white frost on the persimmon?

In fact, the white frost on the persimmon is that when the persimmon is baked into the persimmon, the water gradually evaporates, and the glucose and fructose contained in the pulp will penetrate into the epidermis. Because the properties of the two sugars are different, fructose tastes sweet and is easy to absorb water. When it penetrates into the surface of the persimmon, it will adhere to the epidermis of the persimmon, and the sweet taste of glucose is not as sweet as fructose, and it is difficult to absorb the air When it penetrates the surface of persimmon, it just wraps the adhered fructose to form the layer of white powder we see. In fact, this layer of white powder is glucose powder. Many people who don't know how to eat persimmon will wash off this layer of white frost with water. It's a pity for Xiaobian. Because this layer of white cream is a big treasure in the eyes of traditional Chinese medicine.

What's the use of the white cream on the persimmon?

According to TCM:

The white frost on the persimmon cake is sweet and cool. It has the functions of clearing heat, promoting fluid production, moistening lung and relieving cough. Persimmon cream can be used to treat chronic bronchitis, dry cough, pharyngitis, etc

But now the persimmons on the market are not good or bad. Some businesses aim at the preferences of consumers and will make artificial 'powder beating' for persimmons, which is harmless to the body, but it has lost the original medicinal value and natural ingredients of the persimmon cream. Although persimmon cream is good, you must see it clearly when selling persimmons. You'd better take it up and shake it. If there is white powder falling, you'd better not sell it. Normal persimmon surface has a layer of slightly white frost, this layer of thin frost is not evenly distributed, the top is heavier, and some have frost circle. And the persimmon that natural air basks out feels more dry, won't drop pink.
