Allura red dye. Allura Red AC is a red azo dye that goes by several names including FDC Red 40. It is used as a food dye and has the E number E129. It is usually supplied as its red sodium salt but can also be used as the calcium and potassium salts.

These salts are soluble in water. In solution its maximum absorbance lies at about 504 nm. 921 Byproducts of the petroleum industry are used to produce.

Allura Red AC dyes production and use as a color additive in foods drugs and cosmetics may result in its release to the environment through various waste streams. If released to air Allura Red AC dye will exist solely in the particulate phase in the atmosphere since it is a salt and will be nonvolatile. Particulate-phase Allura Red AC dye will be removed from the atmosphere by wet or dry.

Red Dye 40 is one of the most widely used food dyes as well as one of the most controversial. The dye is thought to be linked to allergies migraine and mental disorders in children. Allura Red red dye 40 has a molar mass of 49642 gmol.

It usually comes as a sodium salt but it is soluble in water. In aqueous solutions its λ max is around 504 nm. Allura Red was approved for use in food in 1971 after Allied Chemical Corporation subjected it to the most expensive and thorough testing program that had ever been given to.

RED DYE 40 AND THE BRAIN. The brain imaging work at Amen Clinics demonstrates that Red Dye 40 can dramatically affect brain function. Consider the case of Robert a 15-year-old who underwent brain SPECT imaging at Amen Clinics.

SPECT is a functional brain imaging tool that measures blood flow and activity in the brain. Calibration standard solutions of the red food colour dye Allura Red Red 40 will be prepared from a supplied stock solution by serial and multiple dilutions. The visible light absorbance of each of the prepared calibration solutions will be measured.

From the absorbance values of the prepared calibration solutions a calibration line of absorbance against concentration will be constructed. This is probably the most obvious source for allura red but dont just read the labels on red candy. Often red dye is mixed with a yellow dye to create a golden caramel coloring.

Other color mixes are created to give candies unusual colors or cheaper dye alternatives to traditional non-synthetic coloring. Sodas sports drinks teas juices. Sodas and soft drinks are also obvious places.
