Abstract: The sweetner prepared by adding palatinose to sucrose is a low-cariogenic since palatinose is not only low cariogenic in itself, but also inhibits the formation of insoluble glucan from sucrose in an oral cavity.Since the sweetner is almost same as sucrose in quality of sweetness, dissolvability in a mouth, palatability, etc., and further is low-cariogenic when it is used in foods, it is suitable as sweetner. In addition, since the sweetner is usually crystalline or powdery, it is easy to handle.
