Comparing:
E211: Sodium Benzoate (Acid Beverage Preservative)
E635: Disodium 5'-Ribonucleotides (I+G Blend)
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.
E635 (I+G) is a standardized 50/50 co-crystallized blend of disodium inosinate (E631) and disodium guanylate (E627). INS 635, ADI is Not Specified, serving as the commercial standard umami booster in global food manufacturing.
