Abstract
The objective was to investigate the detailed information about proximate, fatty acid compositions and lipid quality indices in the caviar of wild and farmed beluga, Huso huso from Iran. The fatty acid composition varied with origin of caviars, although did no differ in proximate compositions. The most notable difference (P 0.05). There were significantly differences between samples in the amount of eicosapentaenoic (C20:5n-3), arachidonic (C20:4n-6) and docosapentaenoic (C22:5n-3) acids (P 0.05). Total ω-6 was higher in farmed samples (P 0.05). The present study indicated that, fatty acids profile in beluga caviars can be used as an index to determine fish origin and diet. Also farmed beluga caviar has good balanced with lipid quality indices to decrease the potential risk of coronary heart diseases and like wild ones could be considered as a good food sources.
