Emerging technologies have been developed in response to global needs and consumer needs. These requirements include low waste, low energy, low process intensity, less chemistry, waste minimization, quality retention, low temperature processing and improved sensory, nutritional and functional properties.

So far the most successful and accepted technologies include high pressure processing, pulsed electric field technologies, cold plasma applications and ultrasound processing.

A description of these technologies, their advantages, limitations and potential will be given. In addition, examples for application for preservation and functionality modification will be given. The potential of these emerging technologies for dairy processing and product modification will also be discussed
