E150d: Sulfite Ammonia Caramel (Class IV Caramel) vs. E202: Potassium Sorbate (Soluble Antimicrobial)
Comparing 2 standards across 10 specifications. 10 key differences identified.
Comparing:
E150d: Sulfite Ammonia Caramel (Class IV Caramel)
E202: Potassium Sorbate (Soluble Antimicrobial)
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.
E202 (Potassium Sorbate) is the potassium salt of sorbic acid, offering 58% water solubility at room temperature. INS 202, group ADI is 11 mg/kg bw/day, widely utilized in beverages, syrups, and cosmetics to block yeast fermentation.
