Comparing:
E200: Sorbic Acid (Antifungal Preservative)
E500: Sodium Bicarbonate (Baking Soda / Ins 500ii)
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.
E500 (Sodium Carbonates / Sodium Bicarbonate NaHCO3) is a mineral salt leavening agent and pH buffer. INS 500(ii), ADI is Not Limited (Quantum Satis), decomposing under heat and acid to produce carbon dioxide bubbles that expand cakes, cookies, and pretzel crusts.
