Comparing:
E170: Calcium Carbonate (Mineral White Color / Anti-Caking)
E200: Sorbic Acid (Antifungal Preservative)
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.
E200 (Sorbic Acid / 2,4-hexadienoic acid) is an unsaturated organic carboxylic acid preservative with broad antifungal and antimold activity. INS 200, group ADI is 11 mg/kg bw/day (expressed as sorbic acid), active across acidic and neutral pH up to 6.5.
