Usage pattern and exposure assessment of food colours in different age groups of consumers in the State of Uttar Pradesh, India.
The present study aims to investigate the nature and levels of colours in food items and to undertake risk assessment vis-a-vis intake among different age groups of consumers in the State of Uttar Pradesh, India. A total of 478 edible foodstuffs were analysed, and of six permitted colours, Sunset Yellow FCF (SSYFCF) and Tartrazine were most popular, and two non-permitted colours, namely Metanil Yellow and Rhodamine B, were encountered. The study showed a marked improvement in the trend of use of non-permitted colours over previous surveys, with 90% foods now resorting to approved food colours. However, 59% of foods employing permitted colours exceeded the maximum allowable limit, with average quantities crossing the threshold of 100 mg kg(-1) in most food commodities. The intake of SSYFCF exceeded the acceptable daily intake (ADI) for children and adolescents by 88% and 39%, respectively, and was statistically significant when analysed by error bars and distribution curves. In adults, SSYFCF saturated 59% of the ADI. For Carmoisine, Tartrazine and Ponceau 4R, saturation of ADI ranged from 27.4% to 90.3% in children and adolescents and from 10.8% to 47.6% in adult subjects. These results indicate that children and adolescents are more vulnerable to higher intakes of food colours compared with the adult population. Allowing a uniform level of all colours in foods under Indian rules, notwithstanding wide variations of 250-fold in their allocated ADIs, could be one reason for the higher intake and hence only technological need-based levels of individual colours are desired to be prescribed.
