E250: Sodium Nitrite (Curing Salt / Anti-Botulism Preservative)
E410: Locust Bean Gum (Carob Bean Gum / LBG)
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.
E410 (Locust Bean Gum / LBG) is a galactomannan polysaccharide milled from the seeds of the carob tree (Ceratonia siliqua). INS 410, ADI is Not Limited (Quantum Satis), providing smooth melt-down and freeze-thaw ice crystal inhibition in premium ice creams.
