Study on Annual Component Analysis of Pacific Oysters (Crassostrea gigas) and Mussels (Mytilus galloprovincialis) | Chapter 8 | Emerging Challenges in Agriculture and Food Science Vol. 1

 The annual obesity ratio, umami components (glutamic acid and glycogen), functional components (Zn, Mn, Cu, and vitamin B12), and Cd and noroviruses (NoVs) contents of Pacific oysters (Crassostrea gigas) and mussels (Mytilus galloprovincialis) were quantified to study the change in components over a year.

The obesity ratio and chemical components in oysters changed seasonally depending on the spawning season. From November to March, the glutamic acid content rose. Glycogen content, on the other hand, peaked in May and November. During spawning, mineral content increased dramatically. According to the NoVs GI and GII strains, oysters are primarily infected by the GI. Depending on the oyster farms, there was a significant variance in NoVs content.

The levels of glutamic acid, zinc, and copper in mussels were constant throughout the year. The Cd concentration of mussels was one-fifth that of oysters. Despite the fact that the NoVs strain was altered by the collecting area, mussels from both areas had lower NoVs concentration in the summer, which corresponded to the mussel consumption season in Japan.

Our comparative research of seasonal variations in chemical components and NoVs content in pacific oysters (C. gigas) and mussels (M. galloprovincialis) revealed a clear link between physiological parameters and reproduction on farms.
