Compositions, their use, and methods for their formation
Compositions comprising polysaccharides and oligosaccharides are provided. Methods for the formation of the compositions, including the enzymatic production of the oligosaccharides, and the uses of the compositions in foodstuffs, cosmetics, and nutraceuticals are also provided.
