Comparing:
E220: Sulfur Dioxide (Antioxidant & Wine Preservative)
E967: Xylitol (Birch Sugar / Dental Caries Inhibitor)
E220 (Sulfur Dioxide / SO2) is an inorganic gas dissolved in water to generate bisulfite and sulfite ions, providing potent antimicrobial and polyphenol oxidase enzyme-inhibiting properties. INS 220, group ADI is 0.7 mg/kg bw/day.
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.
