E250: Sodium Nitrite (Curing Salt / Anti-Botulism Preservative)
E967: Xylitol (Birch Sugar / Dental Caries Inhibitor)
Sodium nitrite (E250, NaNO2) is an inorganic salt used in cured charcuterie, bacon, and processed meats to inhibit Clostridium botulinum neurotoxin germination, fix cured pink nitrosyl-myoglobin color, and retard lipid autoxidation.
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.
