Additionally, high activity of endogenous proteolytic enzymes could degrade myosin and result in a breakdown of gel structure in the temperature range. Dissociation of actin-myosin and the dena- turation of myosin tail could increase the protein mobility and break the network structure of gel. Upon further heating. G increased sharply to approximate 65 Cand then increased moderately to 90 °C, which might be caused by the formation of up a stable gel structure due to continuous protein aggregation(Liu et al.. 2007)
