Since centuries foods have been preserved by heating, chilling, drying, salting, conserving, acidification, oxygen-removal, fermenting, adding various preservatives, etc., and often these methods were applied in combinations. More recently the underlying principles of these traditional methods have been defined (i.e., F, t, aw, pH, Eh, competitive flora, various preservatives), and effective limits of these factors for microbial growth, survival, and death were established. Food preservation and also food quality depends in most cases on the empirical and now more often on the deliberate and...

Hurdle Technologies: Combination Treatments for Food Stability, Safety and Quality is the first work on hurdle technology in which all aspects, the possibilities and limitations of hurdle technology, are comprehensively outlined and evaluated. World-renowned on the subject, Leistner and Gould were instrumental in the development of the hurdle technology concept and in the last decades have obtained much practical experience in the application of this successful approach in the food industry worldwide.
