Summary:
Milk preservation depends upon refrigeration and boiling, but in developing countries these methods are costly and often impractical due to the sporadic availability of continuous electricity. New research now finds that short pulsed electric fields can be used to kill milk-contaminating bacteria. This process can prevent bacteria proliferation in stored milk, potentially increasing its shelf life.
Even though much of the population in developing countries is involved in agriculture, food security is virtually out of reach. Often the only resort is to purchase a cow, buffalo, or sheep, to provide a steady supply of fresh milk, a nutritious staple of a daily diet. But how to preserve it safely? Refrigeration and boiling are costly -- and often impossible due to sporadic electricity.
