Variations on the “Blue-Bottle” Demonstration Using Food Items That Contain FD&C Blue #1

Erioglaucine dye (FD&C Blue #1) can be used instead of methylene blue in the classic “blue-bottle” demonstration. Food items containing FD&C Blue #1 and reducing species such as sugars can therefore be used at the heart of this demonstration, which simply requires the addition of strong base...

Summary:Erioglaucine dye (FD&C Blue #1) can be used instead of methylene blue in the classic “blue-bottle” demonstration. Food items containing FD&C Blue #1 and reducing species such as sugars can therefore be used at the heart of this demonstration, which simply requires the addition of strong base such as sodium hydroxide lye.
