The aim of this study was to evaluate the physicochemical and functional properties of the protein recovered from mechanically deboned chicken meat (MDM) obtained by surimi and pH shift processes. The final products were characterized for proximate chemical composition with the protein isolate show in low value of lipids and a higher value of proteins than the surimi. Among these proteins, fractions of myofibrillar proteins actin and myosin were identified by electrophoresis in both products. With these results, it was concluded that it is possible to obtain a protein isolate and surimi with desirable functional characteristics, with high protein value and less lipids and a chemical process applicable in the food industry
