What is the white frost on dried sweet potatoes?

Fresh dried sweet potatoes contain a lot of water, as well as glucose and fructose. When they are dried, the water gradually evaporates, and the glucose and fructose in the pulp penetrate into the epidermis. These two sugars have different properties. Fructose tastes very sweet and easily absorbs water. When it penetrates the surface, it grabs the moisture in the air and sticks to the epidermis, similar to the syrup on the outside of candied fruit. Glucose is not as sweet as fructose, but it is not easy to hold moisture in the air. When it penetrates the epidermis, it becomes a layer of white powder, which just wraps the adhered fructose, making the entire dried sweet potato dry.
