THE RELATIONSHIP BETWEEN GLYCOLYTIC POTENTIAL OF PORCINE MUSCLES AND ULTIMATE PH AND PROCESSING YIELD OF MEAT

The objective of this study was to determine the relationship between glycolytic potential (GP) in porcine M. longissimus dorsi (LD), as measured after in vivo sampling, and ultimate pH (pHu), values and processing yields (RTN) of LD and Semimembranosus (SM) muscles. The LD level of glycogen was proved to be the major determinant of pH_u post mortem because of significant (< 0.05) correlation coefficients between GP-LD and pH_u-LD ( r = – 0.51), RTN-LD (r = –0.58) and pH_u-SM (r = –0.66). Irrespective of pH_u the level of glycogen also influenced the yield of meat processing (for LD). RTN was influenced greatly by pHu (r = 0.70 for pH_u-LD with RTN-LD and r = 0.54 for pHu-SM with RTN-SM). The relationships found between GP-LD and pHu or RTN may benefit the meat quality evaluation in the live animals.

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.
