Commercially available anthocyanins are normally extracted
from grape skins or red cabbage using water, methanol or ethanol.
The colour is pH dependant, ranging from an intense red in
acid conditions turning bluer as the pH rises. (This makes anthocyanins

at the pH of meat).

cherries, ice cream, jellies, pickles, soft drinks, tomato,
carrot or vegetable soups and sweets.
