Seasonal variations influence the nutrient composition of European sardines, with lipid levels peaking from July to September and amino acid content highest during winter.
Network Pharmacology Omega-3 Fatty Acids Sardine
The methodology consisted of analyzing the proximate composition of European sardines from the Adriatic Sea over a period of one year. The nutritional profiles, focusing on free amino acid and fatty acid, were quantified monthly to discern any seasonal variations. The study paid special attention to quantities of bioactive lipids such as omega-3 fatty acids, and essential amino acids, as these are crucial for determining the nourishing value of the sardines for both industrial processing and for health benefits to consumers.
The findings revealed that the nutritional content in sardines displays seasonal variation. The lipid content topped out from July to September, whereas the highest total amino acid content occurred during the winter, from January to March, with histidine, arginine, and threonine being most present. Interestingly, the study noted significant quantities of essential free amino acids throughout the year, with particular surges in March and dips in May. The fatty acid profile predominantly consisted of omega-3 fatty acids, with sardines showcasing high concentrations of eicosapentaenoic and docosahexaenoic acids, which were especially abundant from July to September.
