Comparing:
E224: Potassium Metabisulfite (Campden Salt)
E410: Locust Bean Gum (Carob Bean Gum / LBG)
E224 (Potassium Metabisulfite / K2S2O5) is a white crystalline powder releasing 57.6% sulfur dioxide by weight when dissolved in acidic liquids. INS 224, ADI is 0.7 mg/kg bw/day, the premier sanitizing and stabilizing agent in commercial winemaking.
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.
