E101: Riboflavin (Vitamin B2 Yellow Color) vs. E282: Calcium Propionate (Bread Anti-Mold)
Comparing 2 standards across 9 specifications. 9 key differences identified.
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.
E282 (Calcium Propionate) is the calcium salt of propionic acid, the premier mold and 'rope' bacteria inhibitor in industrial yeast-leavened bakery goods. INS 282, ADI is Not Limited (Quantum Satis), preserving sliced bread for weeks without retarding yeast activity.
