Maltose is a disaccharide in which two glucose molecules are linked by α-1,4 glycosidic bonds, while Isomaltose is a disaccharide in which two glucose molecules are linked by α-1,6 glycosidic bonds. Due to the different molecular conformation, it is called isomaltose to distinguish it from maltose. Generally, maltose is easily fermented by yeast, but isomaltose is not fermented by yeast, and isomaltose is a non-fermentable oligosaccharide.
Isomalt oligosaccharide can effectively promote the growth and reproduction of beneficial bacteria - bifidobacteria in the human body, so it is also called "bifidobacterium growth promoting factor", referred to as "bifidobacterium factor". Syrup is colorless or light yellow, transparent viscous liquid with soft sweetness, no peculiar smell, and no visible impurities; powdered sugar is an amorphous powder with soft sweetness, no peculiar smell, no visible impurities, and is colorless when dissolved in warm water. or light yellow. After years of clinical and practical applications, it has been shown that bifidobacteria have many health-care functions, and isomalt oligosaccharide as a promoting factor of bifidobacteria has naturally attracted people's attention.
