A method and a plant for producing sterile milk which includes separating the raw milk into skim and cream portions, filtering the skim portion to form a first permeate and a first retentate, heat treating the first permeate, filtering the first retentate to form a second permeate and combining the second permeate with one or more of the raw milk, the milk portion or the cream portion. A second filter can have an effective pore size the same as or greater than that of a first filter. The cream portion can be standardized and heat treated, then remixed with the first permeate either before or after heat treatment of the first permeate to form a standardized milk product, which can be homogenized and packaged in aseptic containers. The process can yield at least 95 percent (e.g., 99.8% or more) of the skim milk portion into a usable milk product.
