Cooking is responsible for the setting of gels that make it possible to manufacture sausages and restructured products. Increasing internal temperature results in increased gel strength ( Barbut et al. 1996). Increased gel strength is paralleled by a decrease in soluble protein. Changes in gel structure can be related to changes in protein solubility. The matrix density decreases as temperature is raised ( Barbut et al. 1996). The major changes in microstructure could be related to changes observed in gel rigidity and the reduction in extractable proteins.
