Azodrin residues in cotton seed products

ABSTRACT

Employing a spectrophotometric method, azodrin residues have been dtermined in cotton seed and its related products. It has been significant in the oil in comparison to whole seed and seed cake. Treatments and varieties have also exhibited a significant variation in the amount of azodrin residues. Location has shown non-significant effect on the accumulation of azodrin residues. The residues of six cotton varieties ranged between 2.66 to 4.12 ppm in the crude oil and from 1.62 to 2.41 and 0.77 to 1.96 ppm in the whole seed and seed cake respectively. Storage of cotton seed oil for one year resulted in non-significant effect on the concentration of azodrin residues, whereas thermal cokking procedures of cotton seed oil affected a reduction of 84% of the chemical contaminant
