Comparing 2 standards across 10 specifications. 10 key differences identified.
Comparing:
E150d: Sulfite Ammonia Caramel (Class IV Caramel)
E471: Mono- & Diglycerides of Fatty Acids (Bread Softener)
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.
E471 is an authorized food emulsifier composed of glycerol esterified with one or two fatty acid chains (glycerol monostearate / monooleate). INS 471, ADI is Not Limited (Quantum Satis), globally recognized as the ultimate crumb softener and amylose complexing agent in bakery.
