Grape Skin Extract
Grape Skin Extract is a product that in most parts of the world is used as a by-product for wine or juice production. These grape skin extracts are a great and abundant source for inexpensive anthocyanins that are used in the coloring of food and beverages. The skin of the grape is obtained through aqueous extraction of the grape after the juice has been expressed. As the pH levels shift the hue of the product shifts from red with low levels and blue with higher pH levels. It is often blended with other anthocyanins in novel beverages to enhance the fruity appearance of drinks.
