10 Parameters
Parameter / Spec
E211: Sodium Benzoate (Acid Beverage Preservative)
E410: Locust Bean Gum (Carob Bean Gum / LBG)
E-Number Code
E211 E410
INS / Codex Number
INS 211 INS 410
Functional Class
Preservative (Antibacterial, Antifungal) Thickener, Stabilizer, Syneresis Inhibitor
Acceptable Daily Intake (ADI)
5 mg / kg body weight per day (as benzoic acid equivalent) Not Limited (Quantum Satis)
Primary Mechanism
In acidic media, converts to lipophilic undissociated benzoic acid which disrupts intracellular pH and anaerobic glycolysis in microbes Synergistically cross-links with xanthan gum and carrageenan to form elastic gels and halt ice crystallization
Common Target Foods
Acidic soft drinks, sparkling waters, salad dressings, jams, pickles, soy sauce Ice creams (prevents icy graininess), cream cheeses, infant formula thickeners, fruit sauces
Dietary Compliance
Vegan, Halal, Kosher 100% Vegan (Carob tree seed endosperm), Halal, Kosher
