What are Galactooligosaccharides?

Galactooligosaccharides (GOS), also known as oligogalactosyllactose, oligogalactose, oligolactose or transgalactooligosacchariden (TOS), belong, because of their indigestible nature, to the group of prebiotics. Prebiotics are defined as non-digestible food ingredients that beneficially affect the host by stimulating the growth and/or activity of beneficial bacteria in the colon. [1]

GOS occurs in commercial available products such as food for both infants and adult, ranging from infant formula to biscuits to food for the critical ill. [1]
