Abstract
Food additives have an essential role in food safe by avoiding bacterid growth\ oxidation formation, and other chemical changes in addition to enhance consumer’s taste and it can be classified into synthetic, natural foodstuffs or food coloring materials, which added to foodstuff to make up for colors losses during food processing, to improve natural colors or to add color to food that would be colorless or colored differently
Synthetic food colorings as carmoisine (El22) contains the azo group (—N=N) that
linked to the aromatic rings in the chemical molecular structures used as red color. Natural

food colorants have considerable benefits when consumed. Consumers perceive natural colorants as safer than synthetic colorants, which are believed to be harmful particularly over prolonged use.
The prolonged use of various types of azo dyes can cause certain diseases such as anemia, allergic reactions, asthma, tumors, and cancer which arise from the oxidation of molecules such as DNA or lipids, Antioxidants are substances used to delay or inhibit the oxidation of foods which naturally present in foods, but at very low levels. Therefore, additional quantities are added to control oxidation.
Red beetroot (Beta vulgaris) - a natural antioxidant- is a rich plant source of nutrients that give tremendous health benefits, red beetroot includes anthocyanins and betalains, which are natural antioxidants and can protect against age-related diseases.
Aim of the work
The objective of this study was to investigate the potential protective effects of Beta vulgaris extracts against Carmoisine induced oxidative damage among male rats.
In this study animals were divided randomly into 6 groups (18 animals each). Animals were maintained on food and water. Doses of Beta vulgaris extracts and Carmoisine were prepared by dissolving in distilled water and adjusted according to rat s body weights and given orally by gavages approximately at the same time each morning, 3 days per week for 6 weeks as follow.
