E150d: Sulfite Ammonia Caramel (Class IV Caramel) vs. E509: Calcium Chloride (Firming Agent / Cheese Salt)
Comparing 2 standards across 10 specifications. 10 key differences identified.
E150d (Class IV Caramel) is prepared by heating carbohydrates with both sulfite and ammonium compounds, creating an intensely dark, negatively charged colloid. INS 150d, group ADI is 300 mg/kg bw/day, the global color standard in cola soft drinks.
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.
