E160a: Beta-Carotene (Provitamin A Orange Color) vs. E503: Ammonium Bicarbonate (Baker's Ammonia / Hartshorn)
Comparing 2 standards across 9 specifications. 9 key differences identified.
E160a (Beta-Carotene) is a fat-soluble orange carotenoid tetraterpenoid obtained by synthesis, fermentation of Blakeslea trispora, or plant extraction. INS 160a(i)/(ii), ADI is Not Specified, providing deep orange-yellow hues in dairy, juices, and fats.
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.
