SummaryIn this study physicochemical and quality traits of biceps femoris and longissimus thoracis muscles of male and female Iranian one-humped camel were determined during 14 days of refrigeration storage. Analysis of variance of the results showed that only shear force and temperature were aff ected by the gender (p<0.05). Anatomical location of the muscle infl uenced the meat properties except for drip loss (p<0.05). Also, except for cooking loss, ageing infl uenced the physicochemical and quality properties of meat; during 14 days of storage, proteolysis resulted in an increase of L* and b* values, drip loss and myofibrillar fragmentation index, and the decrease of a* value, expressed juice, shear force and sarcomere length. Proteome changes (myofi brillar proteins) during storage were investigated. Gel analysis revealed that 19 protein spots were signifi cantly changed during 24, 72 and 168 h post-mortem. Fift een spots were identifi ed by MALDI-TOF/TOF mass spectrometer. Correlation analysis revealed signifi cant correlations of actin, troponin T, capping protein, heat shock proteins (HSP) and desmin with physicochemical and quality properties of meat (p<0.05). Actin might be a potential protein marker for colour, tenderness and water-holding capacity, and HSP27 and desmin are good candidate markers for colour and tenderness, respectively.
