E260: Acetic Acid (Vinegar Acidulant / Preservative) vs. E460: Microcrystalline Cellulose (MCC / Dietary Bulking)
Comparing 2 standards across 9 specifications. 8 key differences identified.
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.
E460 (Microcrystalline Cellulose / MCC) is purified, depolymerized wood pulp cellulose prepared by acid hydrolysis. INS 460(i), ADI is Not Limited (Quantum Satis), functioning as a zero-calorie bulking agent, anti-caking agent, and fat mimetic in low-calorie foods.
