Method for producing a ready-to-use, long-life infant milk

Method for preparing a long-life, ready-to-use milk food made as a substitute for breast milk in liquid form, comprising the following stages:

• preparation in two separate tanks of a first phase consisting of a milk composition in a first tank and a second fatty phase in a second tank
• transfer of said first phase from the first tank to a balance tank, via a duct comprising a route of injection of said second phase, wherein said duct comprises homogenisation means between an injection zone of the second phase into the first phase and the balance tank in order to form a pre-emulsion
• cooling of said pre-emulsion in the balance tank and holding at a temperature of between 5 and 10° C. for a period of between 3 and 30 H
• treatment of said cooled pre-emulsion by sterilisation and by a second homogenisation which is performed at high pressure between 500 and 1500 bars to generate a milk food
• packing of the milk food made as a substitute for breast milk thus obtained in an aseptic environment,
• wherein the milk food displays no creaming after three months at 20° C.
