Mannan-oligosaccharides (MOS)

Mannan oligosaccharides (MOS) refer to oligosaccharides derived from partial hydrolysis of mannans, rendering them indigestible. Generally, MOS can be categorized into two types: α-mannose oligosaccharides and β-mannose oligosaccharides. α-Mannose oligosaccharides are obtained through the breakdown of α-(1-6) bonds found in yeast cell wall mannans, whereas β-mannose oligosaccharides are typically sourced from mannan-rich oligosaccharides by cleaving β-(1-4)-glycosidic bonds or derived from plants. Regarded as a premium prebiotic, MOS is often referred to as the "intestinal soft gold."

Mannan oligosaccharides consist of lengthy D-mannose chains forming the main structure, connected by α-(1-6) bonds, along with shorter α-(1-2) and α-(1-3) bonds forming side chains. These functional oligosaccharides are extracted from the cell wall of Saccharomyces cerevisiae. They have the capacity to stimulate and foster the growth of numerous bifidobacteria and lactobacilli, thereby regulating the microecological balance. Furthermore, they serve as high-quality soluble dietary fiber prebiotics.
