Researchers at IMB-CNM-CSIC and the Autonomous University of Barcelona demonstrated a method that concentrates skim milk at room temperature without altering its main protein structures. Their study used an electric field to break liquid into small droplets, allowing water to evaporate without heating.

At an injection rate of 0.01 mL/min, total solids increased from 12.3% to 36.8%. At 0.2 mL/min, solids content barely changed. The experiments used 29 kV and a 10 cm gap between the injection tip and collector.

The process did not produce completely dry milk powder. Processing capacity, energy efficiency and industrial scalability still need to be demonstrated.
