Comparing:
E100: Curcumin (Turmeric Yellow Color)
E211: Sodium Benzoate (Acid Beverage Preservative)
E100 (Curcumin) is a natural diarylheptanoid yellow pigment extracted from the rhizomes of turmeric (Curcuma longa). INS 100(i), ADI is 3 mg/kg bw/day, providing bright yellow-orange coloration in mustard, cheese, and curry powders.
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.
