4. Conclusion
It was observed that freezing protects beef meat against
the detrimental effect of pressure on colour, its original colour
being recovered after thawing. The present work proposes
a combination of conventional freezing and high
pressure–low temperature treatments allowing to produce
beef meat and salt-added beef meat of high hygienic quality
and stability under frozen storage. Additionally, as pressurised
beef meat recovers their original colours after thawing,
it could be commercialised refrigerated without
consumer rejection.
Further research should focus on determining the mechanism
of the reported protective effect. Also, additional
studies should be performed to evaluate the pressurised
beef meat stability under chilled storage, considering particularly the possible recuperation and growth of viable
microbial cells.
