COMPARISON OF THE TEXTURE, RHEOLOGICAL PROPERTIES AND MYOFIBRE CHARACTERISTICS OF SM (SEMIMEMBRANOSUS) MUSCLE OF SELECTED SPECIES OF GAME ANIMALS

The texture, rheological properties and myofibre characteristics of semimembranosus muscles of four different species: wild boar (Sus scrofa), deer (Cervus elephus), roe-deer (Capreolus capreolus), and fallow-deer (Dama dama) shot at 18 months during winter were compared. The muscle texture and rheological properties were determined with the TPA and relaxation tests, performed with an Instron 1140 apparatus. Myofibre characteristics (mean muscle fibre cross sectional area, percentage of type I, IIA and IIB fibres) were measured in muscle samples using a computer image analysis program. The results demonstrate that the highest hardness, cohesiveness, chewiness, the highest mean fibre cross sectional area and percentage of type I fibre were typical of wild boar SM muscle. The lowest textural parameters and percentage of red fibres being recorded in roe deer meat, which at the same time showed the highest elasticity and viscosity.

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.
