Introduction:

initial references of products made with surimi date back in Japan to the 12th century. The technological process was developed in 1972. It is essential to use fresh fish to preserve the nutritional and technological quality of its myofibrillar protein. The highest quality species for elaborating surimi is Alaska pollock, belonging to the cod family. The best part of the fish regarding quality are its fillets or loins.

Objectives:

to evaluate the protein quality of surimi and its omega-3 fatty acid content, and to review the scientific evidence for the role of surimi in relation to health.

Results:

the amino acid score pattern of surimi is above 100 for the 9 essential amino acids, showing good assimilation and digestibility, even higher than that of homologous products such as meat, fish, and eggs. Surimi contributes considerably to the intake of omega-3 fatty acids eicosapentaenoic (EPA) and docosahexaenoic (DHA). Different studies link surimi consumption with positive effects on body composition: increase in skeletal muscle and reduction in white adipose tissue, as well as a tendency to improved muscle motor function. EPA and DHA have a function on both cardiovascular and cognitive parameters.

Conclusions:

one of the main reasons to consume surimi is its excellent protein quality, highlighting its easy assimilation and digestibility. Likewise, surimi's natural content in omega-3 fatty acids EPA and DHA is of great nutritional interest. These components are related to functional effects on body composition, metabolic syndrome parameters, and cognitive level.
