Abstract
Background: There is extensive evidence of tartrazine dye being used in foodstuff
of Qom markets in Iran.
Objective: This study evaluates the synthetic tartrazine dye in some food products and the
health risks caused by tartrazine consumption in Qom province.
Methods: The study has two stages: First, 125 food product samples, including confectionary
products (e.g., candy (Nabat), Poolaky, Charkhandi, cream, and non-cream sweets) and restaurant
products (barbecued chicken), were tested. In the second stage, the risk of exposure to tartrazine
was evaluated.
Results: The results showed that 36.8% of samples in confectionery products (15.8 ± 5.1
mg/kg) and 41.3% of samples in restaurant food (41.5±7.9) were colored with tartrazine dye.
Based on the obtained results, all values of tartrazine levels in the food samples had not exceeded
the maximum tartrazine limit (mg/kg) in food products. Also, the results of exposure
estimation and hazard quotient of tartrazine in age groups revealed that the HQ for age groups
was smaller than 1. Therefore, they show no considerable risk for tartrazine dye intake according
to the food samples in Iran’s market. The probability of total risk (95%) was calculated using
Monte Carlo simulation. Finally, the mean risk calculated for childhood (5 -12) and adult
years (36-55) were determined as 9.35 E-5 and 9.24 E-5, respectively.
Conclusion: This study showed the nonsignificant health risk of exposure to tartrazine in all
study groups according to the amount and frequency of exposure. However, it is recommended
to raise awareness among people concerning the health risks of artificial dye (especially tartrazine
in food), conduct more research for risk assessment of tartrazine, and monitor related data.
