Discrimination of wild and domestic origin of sturgeon ova based on lipids and fatty acid analysis

This study was designed to discriminate different origins of sturgeon eggs (wild or domestic) based on their biochemical composition. Fatty acid profiles of neutral and phospholipid fractions of three populations of white sturgeon, Acipenser transmontanus (two domestic and one wild) and one populati...

Description
Summary:This study was designed to discriminate different origins of sturgeon eggs (wild or domestic) based on their biochemical composition. Fatty acid profiles of neutral and phospholipid fractions of three populations of white sturgeon, Acipenser transmontanus (two domestic and one wild) and one population of wild lake sturgeon Acipenser fulvescens ova lipids were analyzed. Palmitic acid (16:0) was the dominant saturated fatty acid in both neutral and phospholipid fractions of egg lipids regardless of species or population origin. Levels of palmitoleic (16:1 n−7) and docosahexaenoic (22:6 n−3) acids were species specific irrespective of fish origin. Palmitoleic acid was found at a significantly ( P
