E407: Carrageenan (Dairy Stabilizer Hydrocolloid)
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.
E407 (Carrageenan) is a high-molecular-weight sulfated polygalactan extracted from red edible seaweeds (Chondrus crispus / Irish Moss). INS 407, ADI is 75 mg/kg bw/day, famed for stabilizing cocoa suspension in chocolate milk via kappa-casein binding.
