Comparing:
E211: Sodium Benzoate (Acid Beverage Preservative)
E631: Disodium Inosinate (IMP Meat Umami Synergist)
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.
E631 (Disodium 5'-Inosinate / IMP) is the sodium salt of inosinic acid, a purine nucleotide naturally found in aged beef, katsuobushi bonito flakes, and cured meats. INS 631, ADI is Not Specified, multiplying glutamate umami flavor.
