High-quality small green oranges will produce "white frost" on the epidermis, also known as "fruit frost", which is a sugar-containing substance. Fresh small green oranges contain a lot of water, glucose and fructose. When it is dried into preserved fruit, the water gradually evaporates, and the glucose and fructose contained in the pulp then seep into the epidermis and condense into white powdery substances, forming a "fruit cream".
