E412: Guar Gum (Cold-Soluble Galactomannan) vs. E422: Glycerol (Glycerin Humectant & Solvent)
Comparing 2 standards across 10 specifications. 9 key differences identified.
E412 (Guar Gum) is a natural galactomannan hydrocolloid extracted from guar beans (Cyamopsis tetragonoloba). INS 412, ADI is Not Limited (Quantum Satis), boasting 8x the thickening power of cornstarch and hydrating completely in cold water.
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.
