Production steps
Selection of Sturgeon According to Maturity
Age
Sturgeons are raised in aquaculture farms where the temperature is
kept constant throughout the year. It is only after three years
that the sex of the fish can be determined, and at that point,
males and females are separated into different tanks. Females must
then reach a sufficient size and age to produce quality eggs. This
can take anywhere from four to twenty years depending on the
species.
Egg Harvesting
To ensure that the sturgeon has reached maturity, we perform
ultrasounds on the fish. We then conduct a biopsy of the eggs to
determine their size and firmness. When we estimate that the time
has come, the sturgeons undergo a purification step before
harvesting begins.
Sifting
Once the eggs are harvested, they must quickly be sifted to
separate the grains from all impurities.
Rinsing
The eggs are then rinsed to remove any remaining impurities that
may still exist.
Salting
At this stage, the caviar has no taste. The salting step is crucial
to bring out its natural flavor. It all depends on the amount of
salt used; it must be neither too much nor too little. This is when
Mr. Razavi's expertise is essential. His recipe guarantees our
caviar an exceptional taste.
Original Packaging
The caviar is then packaged in original boxes of approximately 1 kg
8. When sealing the box, a weight is placed on the lid to allow the
air present to escape, preventing any oxidation of the product.
This also prevents excess oil from accumulating at the bottom of
the box. Before being sent to our facilities in Waterloo, the
caviar is matured in a cold room for a maximum of four months as it
is a fresh and perishable product.
