Comparing:
E501: Potassium Carbonate (Potash / Alkaline Noodle Salt)
E967: Xylitol (Birch Sugar / Dental Caries Inhibitor)
E501 (Potassium Carbonates / K2CO3) is an inorganic alkaline mineral salt. INS 501(i), ADI is Not Limited (Quantum Satis), used as the key 'Kansui' alkaline agent in Japanese ramen noodles and in the Dutch processing of cocoa powder.
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.
