A method is disclosed for accelerating the ageing process and sterilizing raw meat for extended storage at refrigerated temperatures by treating the meat at ultra-high temperature (UHT), e.g. 900 to 1200 DEG C, for a time sufficient to denature proteins, without burning, to a depth of up to about 2 mm. After UHT treatment the meat is cooled to a refrigerated temperature and packaged in a hermetically sealed container. The meat can be rendered stable for storage at ambient temperatures by subjecting the hermetically sealed meat to electron beam radiation (EBR) at an irradiating dosage sufficient to destroy all mesophilic vegetative pathogens, spores of pathogens, toxins, and spoilage microorganisms which grow at ambient temperatures. UHT pasteurization coupled with high temperature aging for 12 to 24 hours results in meat with tenderness and flavor equivalent to meat aged under refrigeration for 30 to 60 days.
