Every winter is the season when persimmons are on the market in large quantities. Is sweet persimmons your favorite? Persimmons are a kind of food with high nutritional value, but many people will wonder what is the white frost on them?
What sugar is the white frost on the persimmon
On the surface of persimmon, it is usually covered with a thin and even layer of white frost, which is the condensation of glucose and fructose exuded with water evaporation when the pulp is dry. In fresh persimmon, there is a lot of water, but also glucose and fructose. When it is dried into persimmon, the water gradually evaporates, and the glucose and fructose contained in the pulp permeate into the epidermis. But the properties of these two kinds of sugars are different. Fructose is sweet and easy to absorb water. When it penetrates the surface of persimmon, it grasps the water in the air and adheres to the surface of persimmon, which is similar to syrup outside preserves. The sweet taste of glucose is not as good as fructose, but it is not easy to grasp the moisture in the air. When it penetrates the surface of persimmon, it becomes a layer of white powder, which just covers the adhered fructose, making the whole persimmon dry, so the white frost on the persimmon is actually the glucose powder.
The layer of persimmon cake is called persimmon cream, which can moisten dry, dissipate phlegm and stop cough. It can cure dry cough caused by lung heat. It is a sugar containing condensate exuded with the evaporation of pulp water when drying persimmon. The main ingredients are mannitol, glucose, fructose, sucrose, etc., which are light yellow or white. But now many people in the market use lime to fake persimmon cream. When you buy it, you should be careful. If you shake it, you can't buy it.

Put the persimmon cream in the pot and heat it to melt. When it becomes corrosive, pour it into the model, air it to 70% dry, shovel it with a knife, then air it to the whole dry, brush it clean, and it will be persimmon cream cake.
