Abstract

In Dosidicus gigas or jumbo squid, collagen plays an important role in squid swimming mechanisms. Scarce information is available on collagen. The content as well some physical and chemical properties of pepsin-soluble (PSC) and insoluble collagen (IC) were compared in mantle, arm, and fin from adult fresh jumbo squid. The total collagen content and SDS-electrophoresis profile were different in each anatomic part evaluated, the highest IC value was in arms. Scanning electron microscopy (SEM) studies showed same structural arrangement in the PSC from the three anatomical parts and different structural arrangement in the IC. DSC showed a very high transition at 115-120 °C for PSC. The highest Tmax and ΔH was detected in arms collagen. This knowledge will aid to acquire a better understanding and to improve the commercial application of this economically important commodity.
