The aim of this study was to identify and compare the mineral micronutrients compositions, color and genetic structure differences between the wild and farmed Caspian Sea Beluga (Huso huso) sturgeon caviar, which plays an important role to caviar market transparency to prove farmed caviar quality and nutritional values and wild and farmed Beluga caviar genetic identification. Mineral micronutrients were measured by atomic absorption, spectrophotometric and flame atomic emission spectroscopy methods, color by colorimeter and genetic differences by PCR sequencing method. Results showed that, wild samples contained higher amounts of calcium, magnesium, phosphorus and potassium than farmed ones (P<0.05), while, iron, copper and zinc were higher in farmed samples (P<0.05). Sodium content had no significant differences between wild and farmed samples, 4239.43±2.72 and 4237.21±2.18 (µg/g wet weight) respectively (P>0.05). L value in wild sample was 28.29 and in farmed one was 46%, a value was 1.34 and 2.66% and b value was 10.72 and 16.27% respectively (P<0.05), ΔE (color differences) was 15.21 between two samples. Genetic structure had no significant differences between two samples. In conclusion, it can be said that, there was significant differences in mineral micronutrients contents and color but genetic structure did not show any significant differences between two samples.
