Comparing:
E200: Sorbic Acid (Antifungal Preservative)
E422: Glycerol (Glycerin Humectant & Solvent)
E200 (Sorbic Acid / 2,4-hexadienoic acid) is an unsaturated organic carboxylic acid preservative with broad antifungal and antimold activity. INS 200, group ADI is 11 mg/kg bw/day (expressed as sorbic acid), active across acidic and neutral pH up to 6.5.
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.
