E200: Sorbic Acid (Antifungal Preservative) vs. E211: Sodium Benzoate (Acid Beverage Preservative)
Comparing 2 standards across 9 specifications. 9 key differences identified.
Comparing:
E200: Sorbic Acid (Antifungal Preservative)
E211: Sodium Benzoate (Acid Beverage Preservative)
E200 (Sorbic Acid / 2,4-hexadienoic acid) is an unsaturated organic carboxylic acid preservative with broad antifungal and antimold activity. INS 200, group ADI is 11 mg/kg bw/day (expressed as sorbic acid), active across acidic and neutral pH up to 6.5.
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.

|
Primary Mechanism
|
Un-dissociated acid penetrates mold/yeast cell membranes, inhibiting enolase and dehydrogenase enzymes | In acidic media, converts to lipophilic undissociated benzoic acid which disrupts intracellular pH and anaerobic glycolysis in microbes |
|
Common Target Foods
|
Cheese wraps, baked pastries, dried fruits, fermented pickles, wine stabilization | Acidic soft drinks, sparkling waters, salad dressings, jams, pickles, soy sauce |
