Fresh meat is a highly perishable product due to its biological composition. Many interrelated factors
influence the shelf life and freshness of meat such as holding temperature, atmospheric oxygen (O2),
endogenous enzymes, moisture, light and most importantly, micro-organisms. With the increased demand
for high quality, convenience, safety, fresh appearance and an extended shelf life in fresh meat products,
alternative non-thermal preservation technologies such as high hydrostatic pressure, superchilling, natural
biopreservatives and active packaging have been proposed and investigated. Whilst some of these
technologies are efficient at inactivating the micro-organisms most commonly related to food-borne
diseases, they are not effective against spores. To increase their efficacy against vegetative cells, a
combination of several preservation technologies under the so-called hurdle concept has also been
investigated. The objective of this review is to describe current methods and developing technologies for
preserving fresh meat. The benefits of some new technologies and their industrial limitations is presented
and discussed.
