Comparing:
E290: Carbon Dioxide (Carbonation & MAP Gas)
E306: Tocopherol-Rich Extract (Natural Vitamin E Antioxidant)
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).
E306 is a natural mixture of alpha-, beta-, gamma-, and delta-tocopherols steam-distilled from vegetable oils (soybean, sunflower). INS 306, ADI is Not Limited, serving as the gold standard lipid-soluble antioxidant in fats and oils.
