Effect of setting on the gelling properties of a protein concentrate from giant squid ( Dosidicus gigas) mantle
Abstract Different studies on obtaining protein concentrates or surimi from giant squid ( Dosidicus gigas) have reported that soft gels are obtained in comparison with other fish species. Therefore, the aim of this research was to investigate the effect of the setting (30 and 60 °C, for 0, 30, 60,...
