Abstract:
The studied material included 19 fallow deer does hunt-harvested in two seasons, summer and winter. The post-mortem body weight of analysed animals was not affected by the season (P = 0.762). The pH value measured 24 h post-mortem in the M. longissimus lumborum was significantly higher in the summer compared to the winter season. The venison obtained in the winter season characterized with higher L* (P < 0.0001) and b* (P = 0.002) and lower a* (P < .0001) compared to meat from the summer season. There was also a seasonal variation in the purge in vacuum bags (P = 0.001), water compartments and cooking loss (P < 0.0001). Considering the proximal chemical composition, the extractable fat content was higher in winter (P < 0.0001) compared to the summer season. On the basis of the research results, one can conclude about greater usability for processing and storage of venison obtained in the winter season.
