Comparing:
E500: Sodium Bicarbonate (Baking Soda / Ins 500ii)
E967: Xylitol (Birch Sugar / Dental Caries Inhibitor)
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.
E967 (Xylitol) is a five-carbon polyol sugar alcohol produced by hydrogenation of xylose from birch wood or corn cobs. INS 967, ADI is Not Specified, offering 100% 1:1 sugar sweetness, a cooling endothermic mouthfeel, and active inhibition of Streptococcus mutans cavity bacteria.
