ABSTRACT

Abstract The use of additives in different food products is growing up. It has attracted the attention towards the relation between the mutagenic potential of human diseases and food additives. Sunset yellow (SY) and sodium benzoate (NaB) are used as colorant and food additives worldwide. In the present study, genotoxic effects of different combinations of SY and NaB were assessed in vivo in female rats. Different combinations of SY and NaB were dissolved in water and administered daily to six animals groups for 12 weeks. Group 1 (control) received water, Group 2 received 5 mg/kg body weight (bw) SY plus 10 mg/kg bw NaB, group 3 received 5 mg/kg SY plus 100 mg/kg NaB, group 4 received 50 mg SY plus 100 mg/kg NaB, group 5 received 50 mg/kg SY plus 10 mg/kg NaB, group 6 received 200 mg/kg SY plus 750 mg/kg NaB, and group 7 received 20 mg/kg SY plus 75 mg/kg NaB. Genotoxicity investigations (Chromosomal aberration of bone marrow cells, Comet assay and DNA profile of liver cells) were carried out at the end of the experiment. Administration of 200 mg/kg SY plus 750 mg/kg NaB (group 6) induced the highest abnormalities percentage (1.5%) and showed structural abnormalities including end-to-end association, fragmentation, chromatid break, ring chromosome, and centric fusion break of chromosomes. Different combinations of SY and NaB induced an increase in the frequency of tailed nuclei (DNA damage) in liver cells. A concentration-dependent distinct DNA smear pattern was observed in the DNA isolated from liver cells of animals administered SY and NaB. In addition, administration of SY plus NaB resulted in an abnormal distribution of serum proteins. The results showed that the SY plus NaB could have genotoxic potential. With the increase applications of food additives, this study reported important data about screening the potential impacts.
