The aim of this study was to investigate how manipulation of glycolytic rate by post-mortem processing conditions influences quality of aged beef of two bovine muscles of different physiological character, longissimus dorsi (LD) and adductor (AD). Post-mortem glycolysis was manipulated by low-voltage electrical stimulation (LV-ES) of half carcasses and by chilling rate of the muscles. Multivariate statistical analysis was used to visualise the data, while ANOVA was used to identify significant effects and interactions.

- The study examined changes in protein composition in bovine longissimus thoracis muscle during the first 24 hours after death using two-dimensional gel electrophoresis and MALDI-TOF MS/MS.
- Researchers identified 39 proteins that significantly changed, categorizing them into five groups: metabolic enzymes, defense and stress proteins, structural proteins, proteolytic enzymes, and unclassified proteins.
- The findings highlighted specific metabolic enzymes related to energy production and noted the variation in defense and stress proteins, enhancing the understanding of biochemical processes in meat storage postmortem.
Changes in metabolic protein levels in biopsies during the early post mortem period in the bovine longissimus thoracis muscle were investigated by 2-DE based proteome analyses. Nine NRF (Norwegian Red) dual purpose bulls were included in the study. Twenty-four proteins underwent changes between the two sampling times and were classified into two major groups: metabolic proteins and heat shock proteins.
