The present invention relates to a process for obtaining sterile milk, wherein the calcium ion content is reduced preferably to half of the naturally occurring amount by means, for example, of ion exchange or dialysis, and the milk is then filtered sterile, and if desired calcium ions are added again to restore the natural content. The product thus obtained has all of the biological activities as well as virtually the original composition, but it is free of bacteria, fungi and spores and will keep for a longer time.

Process for the sterile filtration of milk

A sterile-filtered colostrum solution that contains casein is made by adjusting the pH of a colostrum solution to 2.5 to 3.5 and then filtering it clear and sterile. It is preferably first defatted, and adjusted to pH 5.5 to 8 after the acid treatment but before being filtered.
