Persimmon cake, also called persimmon cake, is a cake-like food made of persimmon and a famous traditional snack in China. The nutritional value is very high, and the content of vitamins and sugar is about 2 times higher than that of common fruits1~. After air-drying, the surface of persimmon shows white material as persimmon cream, and the main component is fructose. Because persimmon is preserved by dried fruit, naturally dried, and water evaporates, fructose dissolved in water precipitates in this process, forming persimmon cream.
