Title

The effect of selected stabilizers of proteins on the quality of freeze-dried washed mechanically recovered poultry meat

Abstract

The aim of this study was to determine the effect of cryprotectants on the quality of heat formed gels obtained from frozen and freeze-dried washed once with 1% sodium chloride and afterwards twice with water mechanically recovered broiler meat. From the washed mechanically recovered poultry meat (MRPM) six samples were prepared: control and with 0,25% sodium tripolyphosphate (TPP), 8% polydextrose, 8% polydextrose + 0,25% TPP, 8% maltodextrine (DE=15), 8% maltodextrine + 0,25% TPP. The used additives protected functional properties of proteins (protein solubility, thermal drip, texture and colour of gels and total enthalpy of thermal transitions) in the frozen and freeze-dried myofibril preparation. Polydextrose with TPP was found to be the best cryoprotectant.
