E250: Sodium Nitrite (Curing Salt / Anti-Botulism Preservative)
E406: Agar-Agar (Seaweed Hydrocolloid Gel)
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.
E406 (Agar-Agar) is a natural sulfated galactan polysaccharide hydrocolloid extracted from red algae seaweeds (Rhodophyta). INS 406, ADI is Not Limited (Quantum Satis), forming firm, brittle thermoreversible gels with huge hysteresis (melts at 85°C, sets at 35°C).
