E200: Sorbic Acid (Antifungal Preservative) vs. E509: Calcium Chloride (Firming Agent / Cheese Salt)
Comparing 2 standards across 9 specifications. 9 key differences identified.
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.
E509 (Calcium Chloride / CaCl2) is an inorganic calcium mineral salt. INS 509, ADI is Not Limited (Quantum Satis), serving as a crucial firming agent in canned tomatoes, tofu coagulant, and rennet coagulation restorer in pasteurized milk cheese making.
