E163: Anthocyanins (Grape Skin & Berry Red/Purple)
E224: Potassium Metabisulfite (Campden Salt)
E163 (Anthocyanins) are natural water-soluble flavonoid polyphenol pigments extracted from grape skins, elderberries, and black carrots. INS 163, ADI is 2.5 mg/kg bw/day (grape skin extract), exhibiting pH-dependent colors from red to blue.
E224 (Potassium Metabisulfite / K2S2O5) is a white crystalline powder releasing 57.6% sulfur dioxide by weight when dissolved in acidic liquids. INS 224, ADI is 0.7 mg/kg bw/day, the premier sanitizing and stabilizing agent in commercial winemaking.
