E503: Ammonium Bicarbonate (Baker's Ammonia / Hartshorn) vs. E968: Erythritol (Zero-Calorie Fermented Polyol)
Comparing 2 standards across 12 specifications. 12 key differences identified.
E503 (Ammonium Bicarbonate / (NH4)HCO3) is a historic chemical leavening salt. INS 503(ii), ADI is Not Limited (Quantum Satis), decomposing 100% into gaseous CO2, ammonia, and water at temperatures >60°C to create ultra-crisp, airy crackers and cookies.
E968 (Erythritol) is a four-carbon polyol produced by microbial fermentation of glucose by Moniliella pollinis. INS 968, ADI is Not Specified, delivering 70% the sweetness of sucrose with 0.0–0.2 kcal/g, zero GI, and 90% urinary excretion avoiding digestive distress.
