Candy is a kind of confectionery, which refers to a snack with sugar as the main ingredient. If the fruit or nut food is coated with sugar, it is called a sweet food (such as candied haws). In the broad sense of Asian culture, chocolate and chewing gum are also considered as a kind of candy. In Europe and the United States, candy refers only to products made with white sugar or maltose. In ancient times, Europe and the United States even used honey as a raw material to make candy, but because of too much honey, it is not easy to control and not suitable for industrial production. Candy can be divided into hard candy, hard candy, cream candy, gel candy, polished candy, gum candy, aerated candy and tablet candy.
