Is Manganese Violet suitable as a food coloring?
Can I use Manganese Violet as a food coloring? It's safe to use in cosmetics, and I've got some left over, so I was wondering. Is it toxic, edible or actually palatable? Does it have a certain taste? And if it can't be used, are there other Manganese (not magnesium) Compounds that I could use as purple food dye? (Just curious)
Best Answer
As absolutely no-one uses it as a food additive, that should give you some considerable concern.
Aside from that, it's not water-soluable.
The Environmental Working Group (EWG) has a factsheet
Classified as expected to be toxic or harmful
Cameo* (a pigment/paint/colour authority) says this:
Hazards and Safety
Toxic. Inhalation or ingestion of manganese can cause a nervous system disorder.
For lists of approved food additives - see Wikipedia; E number
