What is red cabbage powder?
Red cabbage powder is made by extracting the flavin pigment from red cabbage leaves. This is usually done by boiling in an ethanol and water mixture, resulting in a deep-red/purple solution. This solution is then evaporated under reduced pressure and heat to yield a red/purple powder. The powder smells like cabbage, is soluble in water, and can be used as a dye or acid/base indicator. Many food manufacturers use red cabbage dye as a more 'natural' alternative to synthetic dyes, which are all suspected carcinogens.

What is a cabbage indicator?
The phrase "cabbage indicator" refers to the use of red cabbage juice to indicate the pH of a solution. For red cabbage contains the pigment molecule ka flavin, which is an anthocyanin. In fact, anthocyanin also is responsible for the reds of certain tree leaves such as sassafras [Sassafras albidum] and sourwood [Oxydendrum arboreum]. Anthocyanin has the advantage of being a water soluble pigment. Its color varies depending upon the acidity/neutrality/alkalinity of the solution in which it's found. For example, the anthocyanin pigments in red cabbage juice turn red in acidic, purplish in neutral, and greenish-yellow in basic solutions.
What is red cabbage on the pH scale?
Red cabbage contains a natural pigment called anthocyanin, which changes color based on the pH of its environment. In acidic conditions (pH below 7), red cabbage appears pink or red, while in neutral to alkaline conditions (pH above 7), it turns green or blue.

In baking soda, which is alkaline, the cabbage juice turns blue or green. This color change is due to the interaction between the pigment molecules in the cabbage juice and the different pH levels of the solutions.
