Description:
Due to importance of the color for caviar quality and its export , in this project it has been attempted to identify
elements which yield caviar color . In this respect. Some samples of caviar grade 1A and 1B were taken from
A.guldenstadti and A. persicus species and a complementary sample of A. Stellatus Species grade 2 , the
caviar pigment amounts were measured through HPLC method.
To do this , the required materials were collected Simultaneously, Some Samples were taken from southern
coast of the Caspian sea in Golestan Province were taken to food Industry institute Laboratory in Tehran
Subjected to Axote gas and under darkness . Only a little amount of A. Guldenstadti Caviar grade 1A sample
was gained from cold Storage of Shilat Trading Corp.
The tests are done with standards of the of the pigments with high purity Such as B- Carotene Lutein , Astazantin,Etc. The chemical Substances and solvents used were obtained from merk and Fluka Companies.
Therefore it was Stated that color variety among avarious caviear grads has a meaningful relationship with
the quantities of these pigments in various types of caviar.The quantity of B- caroten , Astaxantin and Lutein
Pigments were found to be more in A. Guldenstadti caviar than in A. persicus Caviar ,and similarly they are
more in caviar 1 A than in 1B in A. persicus and A. Guldenstadti species. As a result , it could be said that there is a significant relation ship between the amount of the pigments and
the light yellowish color of the distinct caviar samples analyzed.
