Comparing:
E211: Sodium Benzoate (Acid Beverage Preservative)
E306: Tocopherol-Rich Extract (Natural Vitamin E Antioxidant)
E211 (Sodium Benzoate) is the sodium salt of benzoic acid, highly soluble and active against yeasts and bacteria in acidic environments (pH < 4.5). INS 211, group ADI is 5 mg/kg bw/day, the standard antimicrobial in carbonated soft drinks and fruit juices.
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.
