Dried persimmon is a cake-shaped food made from persimmons. It is a famous traditional snack in China. It has high nutritional value and contains 1 to 2 times more vitamins and sugar than ordinary fruits. The white substance on the surface of dried persimmon is persimmon frost, the main component of which is fructose. Since dried persimmon is a dried fruit, it is naturally sun-dried. As the water evaporates, the fructose dissolved in the water precipitates in the process, forming persimmon frost. The white frost on persimmon cake is called persimmon frost, which is a condensation of glucose and water. The white frost protects the fructose and preserves the freshness of the persimmon itself.
