Comparing 2 standards across 10 specifications. 10 key differences identified.
Comparing:
E211: Sodium Benzoate (Acid Beverage Preservative)
E412: Guar Gum (Cold-Soluble Galactomannan)
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.
E412 (Guar Gum) is a natural galactomannan hydrocolloid extracted from guar beans (Cyamopsis tetragonoloba). INS 412, ADI is Not Limited (Quantum Satis), boasting 8x the thickening power of cornstarch and hydrating completely in cold water.
