Lactoferrin
A Multi-Benefit Ingredient
Its average concentration in milk is 0.01 g/100ml but lactoferrin is found in higher concentration in whey protein products: 30 to 100 mg/l of sweet whey. Lactoferrin is now produced commercially using cation exchange cross-flow membranes. It can also be isolated by chromatography and other methods. Lactoferrin performs several functions:
- Antibacterial activity
- Regulation of iron transport
- Promotion of cell growth, stimulation of immunity
- Inhibition of free radicals
- Antioxidant properties
- Stimulation of bifidobacteria
