Tartrazine Chemical Properties,Uses,Production

Description

FD & C Yellow No. 5 is principally the trisodium salt of 4,5-dihydro-5-oxo-l-(4-sulfophenyl)-4-[4-sulfophenyl-azo]-lH- pyrazole-3-carboxylic acid.
The colorant is a yellow-orange powder that dissolves in water to give a solution golden yellow at neutrality and in acid. When dissolved in concentrated sulfuric acid, it yields an orange-yellow solution that turns yellow when diluted with water.
FD & C Yellow No. 5 is regularly used in desserts (e.g., dessert powders, puddings, custards, gelatin, ice cream), candy, preserves, beverages (including carbonated soda beverages and flavored drink powders), prepared meats, and canned and frozen vegetables. It is also used in pharmaceuticals and cosmetics.1 .

Chemical Properties

Deep yellow powder

Uses

As a dye for wool and silks; as colorant in food, drugs, and cosmetics. In biochemistry as an adsorption-elution indicator for chloride estimations. Tartrazine (otherwise known as E number E102, C.I. 19140, or FD&C Yellow 5) is a synthetic lemon yellow azo dye used as a food coloring. Tartrazine appears to cause the most allergic and intolerance reactions of all the azo dyes, particularly among as thmatics and those with an aspirin intolerance.

Uses

As a dye for wool and silks; as colorant in food, drugs and cosmetics. In biochemistry as an adsorption-elution indicator for chloride estimations.

Uses

Tartrazine (FD&C Yellow #5) is a colorant. It has good stability to changes in ph, showing no appreciable change at ph 3–8. It has excellent solubility in water with a solubility of 20 g in 100 ml at 25°c. It has good stability to light and heat, fair stability to oxidation, and shows no appreciable change in 10% sugar systems. It has a lemon-yellow hue and has good tinctorial strength. It has moderate compatibility with food components and is used in beverages, baked goods, pet foods, desserts, candy, confections, cereal, and ice cream.

Definition

tartrazine: A food additive (E102)that gives foods a yellow colour. Tartrazinecan cause a toxic response inthe immune system and is banned insome countries.

Definition

ChEBI: An organic sodium salt which is the trisodium salt of tartrazine acid. A synthetic lemon yellow azo dye used as a food colouring.

World Health Organization (WHO)

Tartrazine is widely used as a permitted colouring agent in food and pharmaceutical preparations. Its use has been associated with allergic reactions some of which have been severe. Several national drug regulatory authorities now require a warning on labels of products containing tartrazine and some manufacturers have voluntarily withdrawn this compound from their products.

Hazard

An allergen.

Safety Profile

Low toxicity by ingestion. Mutation data reported. When heated to decomposition it emits very toxic fumes of NOx, SOx, and Na2O.

Toxicology

This coloring agent is 5-hydroxy-1-p-sulfophenyl-4-(p-sulfophenylazo)- pyrazol-3-carboxylic acid, trisodium salt. It is a yellow powder and has been used as food coloring additive since 1916. Tartrazine is known as the least toxic coloring agent among synthetic coloring chemicals. The median acute oral lethal dose of tartrazine in mice is 12.17 g/kg. Beagle dogs received tartrazine as 2% of the diet for two years without adverse effects, with the possible exception of pyloric gastritis in one dog. Tumor incidence was unchanged relative to controls, in rats receiving tartrazine at 1.5% of the diet for 64 weeks, and in rats administered this dye at 5.0% of the diet for two years.
Human sensitivity to tartrazine has been reported with some frequency and has been estimated to occur in 1/10,000 persons. Anaphylactic shock, potentially life-threatening, has been reported but symptoms more commonly cited are urticaria (hives), asthma, and purpura (blue or purple spots on the skin or mucous membrane).

Properties and Applications

yellow. Soluble in water for yellow, slightly soluble in ethanol and soluble fiber. element, insoluble in other organic solvents. The strong sulfuric acid for yellow, yellow solution diluted; In nitric acid solution for yellow. Its water solution with hydrochloric acid discoloration; Add sodium hydroxide is red light deepened. Used for wool, silk, vinegar, polyamide fiber dyeing and printing directly. The Barium salt?also used for paper, leather, soap, drug, plastic, aluminium surface shading, can also be used in cosmetics and food coloring.
