Concentration of cultured (acidified) milk

Purpose

Sterilise skimmed milk to increase shelf life and remove all heat-resistant bacteria.

Solution

Cold sterilisation with Isoflux membranes with a pore size of 1.4 µm is the perfect answer to this challenge. The membranes split the skimmed milk into two parts:

  • a retentate (about one twentieth of the original volume) containing the bacteria and most of the original fat
  • a permeate that is free of bacteria but contains the milk proteins. This fraction represents 95% of the original milk volume. The goal of extracting the bacteria is very well achieved

Benefits

  • Low-temperature sterilisation with complete elimination of bacteria, including heat-resistant bacteria
  • No deterioration in flavour
  • No loss of vitamins or proteins through thermal degradation
  • Increased shelf life of the milk
  • Compact installation (no recirculation loop on the permeate side) and simple operation
  • Long membrane lifespan
