E250: Sodium Nitrite (Curing Salt / Anti-Botulism Preservative)
E414: Gum Arabic (Acacia Gum Emulsifier)
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.
E414 (Gum Arabic / Acacia Gum) is a complex arabinogalactan-protein glycoprotein exudate harvested from Acacia senegal trees. INS 414, ADI is Not Limited (Quantum Satis), the premier film-forming emulsifier for citrus beverage flavor oils.
