EFFECT OF POLYPHOSPHATE AND SOYYA PROTEIN ON TEXTURE AND RHEOLOGICAL PROPERTIES OF SMOKED LOIN OBTAINED FROM PALE, SOFT, EXUDATIVE (PSE)-MEAT.

The effect of cured brine containing polyphosphates and soya protein isolate on texture and rheological properties of smoked loin obtained from normal PSE-meat were studied. Compared to normal loins, the PSE-lions had higher hardness (by about 60%), gumminess (by about 34%) and elasticity moduli (by about 76, 45, 50%), whereas the values of cohesiveness and viscosity moduli were lower by about 21% and 53%, respectively. Adding polyphosphate to the brine lowered the differences between PSE-and normal loins by about 46% for hardness, by about 60, 33 and 37% for elasticity moduli, and by about 19 and 31% for cohesiveness and viscosity moduli. Addition of soya proteins and polyphosphate to the cured brine lowered these differences by about 37% for hardness, 50, 22 and 27% for elasticity moduli, and by 15 and 23% for cohesiveness and viscosity for respectively.

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.
