Comparing:
E101: Riboflavin (Vitamin B2 Yellow Color)
E170: Calcium Carbonate (Mineral White Color / Anti-Caking)
E101 (Riboflavin / Vitamin B2) is an authorized yellow food colorant and essential micronutrient produced via microbial fermentation of Ashbya gossypii. INS 101(i), ADI is 0.5 mg/kg bw/day, commonly used to fortify cereals and color sauces.
E170 (Calcium Carbonate / CaCO3) is a fine mineral salt mined from limestone or precipitated synthetically. INS 170(i), ADI is Not Limited (Quantum Satis), serving as a white surface colorant, acidity buffer, anti-caking agent, and calcium nutrient fortificant.
