Effect of different food stuff colourants added to casein diet on biological evaluation

ABSTRACT

The effect of addition of different food stuff colourants [Chocolate Brown, Tartrazine and Raspberry] to Casein diet of rats was studied. The results showed that all nutritional parameters in rats fed coloured diet were reduced compared with rats fed standard diet in general. The reduction values were about 25% in food consumption [36-50%] in gain in body wt, [16-34%] in PER, [10-12%] in DC, [7-14%] in NPU and [1.5-6%] in BV. that were relative to standard group. Also there was a reduction in the values of the ratio liver wt/body/wt as% relative to the standard group and the reduction ranged between [28-34%]. On the other hand there was slight increase in the percent relative value of BV of Tartrazine about 3% and there were quite increase in the percent relative value of Hb and Hct observed for different colorants
