Sugar-free orange moon cake is a new type of food. In the ingredients of the moon cake, maltitol is used instead of traditional sucrose.

Therefore, using maltose instead of sucrose to make sugar-free moon cakes not only expands the range of people who eat moon cakes, but also improves their commercial value.
