Comparing 2 standards across 9 specifications. 9 key differences identified.
Comparing:
E140: Chlorophyll & Chlorophyllins (Green Color)
E211: Sodium Benzoate (Acid Beverage Preservative)
E140 (Chlorophyll) is the natural magnesium-porphyrin green pigment extracted from grass, alfalfa, and nettles. INS 140(i), ADI is Not Limited (Quantum Satis), utilized to restore vibrant botanical green color to confectionery, oils, and pasta.
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.
