Grape Skin Anthocyanin Natural Red Pigment
Grape Skin Red Color is a natural pigment extracted from the skins of ripe grapes (Vitis vinifera L.), rich in anthocyanins, primarily malvidin, peonidin, and delphinidin derivatives. This pigment appears as a dark purple-red powder, offering a vivid, attractive hue that is water-soluble, safe, and ideal for use in food, beverages, cosmetics, nutraceuticals, and pharmaceuticals.
Grape Skin Red Color belongs to the anthocyanin class of natural pigments, well-known for their antioxidant, anti-aging, and cardiovascular-protective effects. The pigment is highly soluble in water and aqueous ethanol but insoluble in oils and anhydrous ethanol.
Color tone is pH-dependent:
-
Acidic environment (pH 2.5–4.5): Stable bright red to purple-red color
-
Neutral environment (pH 6–7): Blue hue
-
Alkaline environment (pH >7): Greenish and unstable
Due to its excellent visual appeal and natural origin, it is widely used in acidic beverages, fruit juices, wines, jams, jellies, and confectioneries as a natural colorant. Beyond coloring, grape skin extract also provides bioactive antioxidant protection, making it a dual-functional ingredient for clean-label formulations in the modern food and health industries.
