When it penetrates the surface of the persimmon cake, it grabs the moisture in the air and sticks to the pericarp's skin, similar to the syrup outside the candied fruit. The sweetness of glucose is not sugar, but it is not easy to catch the moisture in the air. When it penetrates into the epidermis of the persimmon cake, it becomes a layer of white powder, which just wraps the adhered fructose, making the whole persimmon Dry, so the hoarfrost on the persimmon is actually a powder of glucose.
