Comparing:
E170: Calcium Carbonate (Mineral White Color / Anti-Caking)
E407: Carrageenan (Dairy Stabilizer Hydrocolloid)
E170 (Calcium Carbonate / CaCO3) is a fine mineral salt mined from limestone or precipitated synthetically. INS 170(i), ADI is Not Limited (Quantum Satis), serving as a white surface colorant, acidity buffer, anti-caking agent, and calcium nutrient fortificant.
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.
