Abstract

Highlights:
• The impact of seasonal and geographical variations on the composition of Irish blue mussels was evaluated.
• Samples were obtained from seven locations and four seasons during one year period.
• Content of glycogen, lipid, protein, ash and energy was determined.
• Fatty acid profiles were investigated by GC-FID revealing high contents of PUFAs.
• Spring and summer were identified as optimal harvesting times for Irish mussels.

Abstract:
Blue mussel (Mytilus edulis L.) farming constitutes the largest volume of the shellfish sector in Ireland. Recently, interest in mussel dietary supplements and functional foods has increased significantly. To identify the optimal harvesting time and location in Ireland, blue mussels were investigated for their biochemical composition over a period of one year. The study included samples from aquaculture facilities, wild grown mussels and waste material. Each sample was analysed at four time points to determine the total content of (i) glycogen, (ii) lipids, (iii) proteins, (iv) inorganic substances, and (v) energy. Moreover, fatty acid profiles were investigated by GC-FID revealing high contents of PUFAs and a high ω-3/ω-6 ratio. Compared to less pronounced geographical variations, distinct seasonal trends could be observed for all samples. The content of the investigated metabolite classes, inorganic substances, and energy was at a maximum level in spring or late summer.
