E150d: Sulfite Ammonia Caramel (Class IV Caramel) vs. E410: Locust Bean Gum (Carob Bean Gum / LBG)
Comparing 2 standards across 10 specifications. 10 key differences identified.
E150d (Class IV Caramel) is prepared by heating carbohydrates with both sulfite and ammonium compounds, creating an intensely dark, negatively charged colloid. INS 150d, group ADI is 300 mg/kg bw/day, the global color standard in cola soft drinks.
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.
