Dairy based compositions with low lps

摘要

A method to produce a dairy based food composition with low lipopolysaccharide (LPS) comprises the steps (a) Providing a milk with a storage time of less than 264 hours (11 days old), (b) Treating the milk such that at least 98wt% of the Gram negative bacteria is removed and (c) Heating the milk wherein at least 98wt% of the Gram negative bacteria is removed to 60-90 °C. The method can further comprises (d) Treating the milk with a micro filter of pore size of from 0.05-1.2 m such that at least a casein rich fraction and a serum protein rich fraction are obtained. The treatment to remove at least 98wt% of the bacteria is selected from the group consisting of Bacterial filtration with a poresize of 0.5-2.5 micron; Centrifugation; or Use of antibody to remove Gram negative bacteria. Dairy based food composition obtained by a method is further disclosed. Also disclosed is a dairy based food composition where the amount of lipopolysaccharide (LPS) is less than 4000E3 endotoxin units (EU) per liter ready to use food composition or where the amount of LPS is less than 30E3 endotoxin units (EU) per gram dry product.
