Recent research on bioactive compounds of Scomber spp. and their health effects

Abstract

Scomber spp. are fast-moving migratory fish found in the Pacific, Indian and Atlantic Oceans. Scomber spp. contain proteins, lipids, minerals and vitamins. However, recent studies on Scomber spp. have focused on improving the quality of products (S. colias), describing their morphology (S. indicus), as well as the exploration and application of their enzymes (S. australasicus) and bioactive compounds for health benefits (S. japonicus and S. scombrus). Bioactive compounds from Scomber spp. have been reported to exhibit antibacterial, antioxidant and antiproliferative activities, but there has been no review of this topic to date. Totally, 36 articles were reviewed after the duplicates were removed. Muscle protein hydrolysates, peptides, lipids, collagen, amino acids, lecithin and glycolipids are known as bioactive compounds from Scomber spp. that exhibit beneficial health effects, including antioxidant, antibacterial, antiproliferative, tyrosinase inhibition, hypoglycaemic and anti-lipoxygenase properties. However, these have been tested only in vitro, and there is still a lack of studies on bioactive compounds from S. australasicus, S. colias and S. indicus. Therefore, further studies are needed to test bioactive compounds from Scomber spp. at the in vivo and clinical stages, as well as to explore the presence of bioactive compounds from S. australasicus, S. colias and S. indicus.
