E163: Anthocyanins (Grape Skin & Berry Red/Purple) vs. E290: Carbon Dioxide (Carbonation & MAP Gas)
Comparing 2 standards across 10 specifications. 10 key differences identified.
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.
E290 (Carbon Dioxide / CO2) is an authorized food additive functioning as a carbonating gas, modified atmosphere packaging (MAP) preservative, and cryogenic freezing propellant. INS 290, ADI is Not Limited (Quantum Satis).
