E410: Locust Bean Gum (Carob Bean Gum / LBG) vs. E422: Glycerol (Glycerin Humectant & Solvent)
Comparing 2 standards across 10 specifications. 9 key differences identified.
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.
E422 (Glycerol / Glycerin) is a sweet, viscous trihydroxy alcohol (polyol) obtained via lipid hydrolysis. INS 422, ADI is Not Limited (Quantum Satis), acting as an essential humectant, moisture retainer, and freeze-point depressant in baked goods and icings.
