Abstract:
Caviar is one of the valuable and most popular fish
products all over the world that are
obtained from sturgeons. Nowadays, the wild resourc
es of these fishes are diminished,
therefore, to meet the demand for the product, farm
ing sturgeons has been considered.
The chemical composition and the amino acids profil
es of the wild and farmed roe
obtained from beluga (
Huso huso
) were compared and the results have indicated that
the
amount of glutamine, serine, alanine, methionine, a
nd lysine in the wild roe were higher
than the farmed one (P< 0.05). The total amino acid
s (TAAs) and the ratio of essential
amino acids (EAAs) to TAAs and EAAs to non-essentia
l amino acids (N-EAAs) in the
samples from the wild and farmed roe were similar (
P> 0.05). The protein efficiency ratio
(PER) and chemical score in farmed and wild roe wer
e also similar (P> 0.05). The results
showed that the farmed roe was similar to the wild
one based on chemical composition,
chemical score, PER, EAAs/TAAs and EAAs/N-EAAs. Acc
ording to the results, farmed
roe can be a good substitution for wild beluga roe
(
Huso huso
).
