Functional sugar
Functional sugars are a type of carbohydrate with special functions, mainly including functional oligosaccharides, functional dietary fiber, and functional polyols. Due to the special effects of functional sugars, they can be added as a functional ingredient in food and can also be used as a substitute for sucrose in food, reducing the impact of sugar in food on special populations. From a purely chemical perspective, functional sugars actually refer to a collective term for several substances with special physiological effects, such as functional oligosaccharides, functional dietary fiber, and functional polyols.
