Abstract

Amaranth is one of the most synthetic coloring agents widely used in food as an additive. The present investigation was carried out for studying the effect of daily administration of amaranth with a dose equal 50 mg /kg b.w. for two different time periods (7 and 21 days), using male albino rats. The effect of amaranth on growth performance, haematological and biochemical parameters were examined throughout the investigation. The data revealed marked changes in treated groups as compared with the control. They showed a decrease in percentage of body weight change, red blood cells (RBCs) count and haemoglobin (Hb) concentration, but the results recorded an increase in mean corpuscular volume (MCV) and white blood cells (WBCs). Also, there was a decrease in glucose level. On the other hand there was an increase in the activity of aspartate aminotransferase (AST), alkaline phosphatase (ALP), cholesterol, triglycerides, urea, creatinine and thyroid stimulating hormone (TSH) levels in the amaranth treated rats.
Key words: food additives, amaranth, haematological parameters, biochemical parameters, albino rats.
