“…Previous works have informed on the physico-chemical, biochemical, and functional properties of major myofibrillar proteins from squid Illexargentinus (Paredi, Roldán, & Crupkin, 2006;Mignino & Paredi, 2006). It had been also reported that, cephalopods have peculiarities of proteins and high level of proteolytic activity, higher than that of most fish species (Hurtado, Borderías, Montero, & An, 1999). Moreover, it has been reported that some of the proteases involved in that proteolytic activity, have as target the myosin heavy chain (MHC) producing degradation of the same (Konno & Fukazawa, 1993;Konno, Yuong-Je, Yoshioka, Shinhho, & Seki, 2003).…”
