E150d: Sulfite Ammonia Caramel (Class IV Caramel) vs. E260: Acetic Acid (Vinegar Acidulant / Preservative)
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.
E260 (Acetic Acid / Ethanoic acid) is a natural carboxylic acid produced via aerobic Acetobacter fermentation of ethanol. INS 260, ADI is Not Limited (Quantum Satis), giving vinegar its characteristic pungent sour flavor and pickling preservative action.
