Minimal Processing Technologies in the Food Industry

edited by Thomas Ohlsson
and Nils Bengtsson


Consumers increasingly demand foods which retain their natural flavour, color and texture and contain fewer additives such as preservatives. In response to these needs, one of the most important recent developments in the food industry has been the development of minimal processing technologies designed to limit the impact of processing on nutritional and sensory quality and to preserve food without the use of synthetic additives. Minimal Processing Technologies in the Food Industry covers the range of minimal processing techniques, their advantages and disadvantages, and their use in food production.

Minimal Processing Technologies in the Food Industry will be widely welcomed as a comprehensive and authoritative resource on one of the most important areas in food processing.
