Electricity Key to Fresh-tasting, Long-lasting Milk
Promising New Technology Treats Milk at Ultra-High Temperatures
Thanks to research funded by America's dairy farmers, electricity moves beyond its initial intent of providing a well-lit home or milking parlor to
help create an ultra-high temperature (UHT) milk with a fresh, appealing taste.
Existing commercial methods for UHT treaTMent of milk create "cooked" flavor notes that can detract from the fresh taste. But researchers at the
Western Dairy Center at Utah State University in Logan, Utah, in a project managed by Dairy Management Inc.TM (DMI), are using electricity to look at
a promising new process for ultra-high temperature milk processing.
By passing electrical current directly through pasteurized milk, the milk is flash-heated to destroy virtually all bacteria present. This improved
technology delivers a more appealing, fresher-tasting milk with an extended shelf life.
The secret of the new technology, known as electroheating and developed by Raztek Corporation in Sunnyvale, Calif., is a fast, direct heat
"By passing an electrical current directly through the milk itself, we are able to reach UHT levels in a fraction of a second, rather than minutes,"
says McMahon. "This quicker heating process is the key to producing a fresher-tasting milk product."
