CHANGES IN CHEMICAL COMPOSITION OF MEAT FROM ROE DEER ( CAPREOLUS CAPREOLUS  L.) BUCKS DURING COLD STORAGE UNDER VACUUM AND MODIFIED ATMOSPHERE

Changes in the chemical composition, nitrogen content of water extracts, weight loss and shear force of meat from roe deer (Capreolus capreolus L.) bucks were analysed during 21-day cold storage (2^oC) under modified atmosphere conditions (vacuum; 40% CO₂ + 60% N₂; 60% CO₂ + 40% N₂). A gradual increase in drip loss was observed over the storage period. The process of cold storage of roebuck meat in a modified atmosphere (MA) had no significant effect on the content of major chemical components. The dynamics of changes in the content of nitrogen compounds in water extracts of cold-stored meat was lower in MA-packaged samples, compared to the vacuum-packaged samples. The relatively low rate of protein degradation (proteolysis) in roebuck meat during ageing was reflected in the lack of considerable changes in the average values of shear force.

W latach 2022-2024 kwartalnik naukowy Polish Journal of Food and Nutrition Sciences realizuje projekt nr RCN/SP/0520/2021/1 finansowany ze środków budżetu państwa – Ministerstwo Edukacji i Nauki w ramach programu „Rozwój czasopism naukowych”. Dofinansowanie wynosi 120 000 zł. W ramach projektu podejmowane są działania zmierzające do podniesienia poziomu praktyk wydawniczych i edytorskich, zwiększenia wpływu czasopism na rozwój nauki oraz utrzymania się czasopism w międzynarodowym obiegu naukowym.

In the years 2022-2024, the scientific quarterly Polish Journal of Food and Nutrition Sciences accomplishes a project no. RCN/SP/0520/2021/1 financed from the state budged – Ministry of Education and Science Republic of Poland in the framework of a program “Development of scientific journals”. The financing amounts to 120,000 PLN. The program aims at improving the level of publishing and editing practices, increasing the impact of scientific journals on science development, and extending the international range of scientific journals.
