Comparing 2 standards across 9 specifications. 9 key differences identified.
Comparing:
E162: Beetroot Red (Betanin)
E211: Sodium Benzoate (Acid Beverage Preservative)
E162 (Beetroot Red / Betanin) is a water-soluble red-purple betacyanin pigment pressed or extracted from red beets (Beta vulgaris). INS 162, ADI is Not Limited (Quantum Satis), used in dairy, ice creams, and sausages.
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.
