E338: Phosphoric Acid (Cola Acidulant) vs. E410: Locust Bean Gum (Carob Bean Gum / LBG)
Comparing 2 standards across 10 specifications. 10 key differences identified.
E338 (Phosphoric Acid / H3PO4) is a mineral inorganic acid providing a uniquely dry, tangy, astringent sourness. INS 338, group ADI is 40 mg/kg bw/day (as phosphorus), the quintessential acidulant in cola beverages and processed cheeses.
E410 (Locust Bean Gum / LBG) is a galactomannan polysaccharide milled from the seeds of the carob tree (Ceratonia siliqua). INS 410, ADI is Not Limited (Quantum Satis), providing smooth melt-down and freeze-thaw ice crystal inhibition in premium ice creams.
