Abstract

Colour in food is an integral part of our culture and is also indispensable to the modern day consumer. During the past several decades, the technology of food processing has changed dramatically and the growth in the use of synthetic food colours as an individual dye or in the form of blends has increased enormously. In the present investigation, an attempt has been made to evaluate the toxic effects of a commonly used dye blend, tomato red on male Swiss albino mice. The mice were treated orally with 2 and 6g/kg body weight/day for 42 days. The present study revealed an increase in the body weight and liver weight. However, a decrease was recorded in the weights of kidneys and testes. Histopathological study revealed severe degenerative changes in the liver, kidney and testes. In conclusion, the use of the dye blend in various food items has adverse effect on the vital organs.
