# Electrospray concentrates milk without heat

> Researchers at IMB-CNM-CSIC and UAB in Barcelona demonstrated that high-voltage electrospray can concentrate liquid milk at 20°C. In lab tests, slowing the feed rate raised total solids from 12.3% to 36.8%, cutting water content by nearly half while keeping proteins intact. The method is being patented.

## Why it matters

This is an early-stage lab technique with no near-term effect on dairy supply or prices. If scaled, a nonthermal concentration method could eventually lower energy use in milk powder production.
