Abstract

INTRODUCTIONConsumers are increasingly aware of the positive effects of marine fishery products, which are associated with high levels of beneficial nutrients for human health. Increased market demands have resulted in an intense pressure on species of commercial importance and an increasing requirement for food quality (i.e. the authenticity evaluation and origin of species). Squid is an important seafood resource for Asian and European countries. Jumbo squid (Dosidicus gigas), one of the main target species in the international market, is the most abundant ommastrephid squid in the eastern Pacific Ocean. Throughout its large distribution range, several harvest regions are located off the coasts of western South and Central America and the Gulf of California. The commercial annual catch exceeded 1 million tons in 2014, which is almost 24% of the total fishery products of cephalopods. Frozen D. gigas are sold for direct consumption by consumers, and a burgeoning literature documents other processed food products developed from jumbo squid, such as collagen, gel‐based products, and mince. With the continuous development of jumbo squid products, methods aimed to improve food quality and information, such as regional identity, are needed. Moreover, the market value of raw squid differs between fishing regions and it
