Human Milk Oligosaccharides

2'-Fucosyllactose (2'-FL)

Please contact us for further details:

Most human milk oligosaccharides are fucosylated oligosaccharides, which is not the case for the oligosaccharides produced by dairy animals. The most abundant oligosaccharide in human milk is
2′-Fucosyllactose, with a concentration of about 2 grams per liter.


Because 2‘-fucosyllactose is present in relatively high concentrations in human milk, it was possible (even many years ago) to isolate and investigate this compound. Its specific functional benefits include its ability to reduce the risk of infection by widespread bacterial diarrheal pathogens, e.g. Campylobacter jejuni, pathogenic Escherichia coli, certain Salmonella species and the pneumonia-causing pathogen Pseudomonas aeruginosa. In cooperation with the University Children’s Hospital Mannheim of Heidelberg University, Jennewein Biotechnologie has confirmed the functional equivalence of our products 2′-Fucosyllactose and 3-Fucosyllactose. Further preclinical studies suggest, that 2′-Fucosyllactose also has positive effects on the nervous system and cognition, as well as reducing the risk of inflammation such as in the case of necrotizing enterocolitis, for example.

Jennewein Biotechnologie produces 2′-Fucosyllactose on a commercial scale under FSSC 22000 and ISO 9001. The product is available as a spray-dried powder. Our 2′-Fucosyllactose production facility is Kosher (Orthodox Union) as well as Halal (Halal Food Council of Europe) certified.
