Abstract
Previous studies have suggested that food dyes are responsible for causing number of health problems. The study under consideration aims to show the possible morphological and skeletal malformation induced due to in ovo administration of sunset yellow (SY) and tartrazine (Tz) with or without curcumin (Cur) during organogenesis of developing chick embryo at doses 1.575mg/egg, 0.375mg/egg and 3mg/kg eggs for SY, Tz and Cur comparing with control. The investigation revealed evident reduction in the weight and length of embryos as well as malformations in feather, head, and limbs. Most of the congenital malformations were seen in SY and Tz injected groups such as short beak, excencephaly, kniked tail and pygostyle, curved scapula and retardation in the degree of ossification were the most evident in endoskeleton malformation. In addition, the length of ossified long bones in SY and Tz groups was affected. Co-administration of Cur with SY and Tz ameliorate the reversed effect of SY and Tz on the shape, length, body weight and skeleton of embryos.
Highlights
Food additives are products added to the food stuffs with an aim of improving its, flavor, taste, color, texture and conservation (Tawfek et al, 2015)
The present study was planned to illustrate the possible morphological and skeletal malformations induced by three food coloring agents on the development of chick embryo and the anticipated role of natural color against the toxicity induced by synthetic coloring agents
Our result revealed that there was a significant difference in the mortality rate of chick embryos between the experimental synthetic coloring agents administrated group and the other groups as there was low mortality among control, sham and Cur groups
Summary
Food additives are products added to the food stuffs with an aim of improving its, flavor, taste, color, texture and conservation (Tawfek et al, 2015). Curcumin (Cur) is a polyphenolic natural food color found in Turmeric (curcuma longa) used as a spice and has vital role in both medical and scientific field. It is widely used as food coloring pigment and preservative. In vivo and in vitro studies reported that Cur has a protective against oxidative stress (Menon and Sudheer, 2007) It has the ability of scavenging different forms of free radicals. Tartrazine (Tz) (E102) is an artificial lemon yellow azo dye derived from coal tar It is water soluble mono azo color which used in human food, pharmaceutical products and cosmetics. The present study was planned to illustrate the possible morphological and skeletal malformations induced by three food coloring agents (natural and synthetic) on the development of chick embryo and the anticipated role of natural color against the toxicity induced by synthetic coloring agents
