E300: L-Ascorbic Acid (Vitamin C Antioxidant & Flour Improver) vs. E460: Microcrystalline Cellulose (MCC / Dietary Bulking)
Comparing 2 standards across 13 specifications. 13 key differences identified.
L-Ascorbic Acid (E300, C6H8O6) is a water-soluble antioxidant, dough conditioner, and vitamin fortifier that scavenges dissolved oxygen, prevents fruit enzymatic browning, and cross-links wheat gluten disulfide bridges in commercial baking.
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.
