E440: Pectin (Citrus & Apple Jam Gelling Fiber) vs. E460: Microcrystalline Cellulose (MCC / Dietary Bulking)
Comparing 2 standards across 10 specifications. 9 key differences identified.
E440 (Pectin) is a complex heteropolysaccharide rich in alpha-(1->4)-linked D-galacturonic acid extracted from citrus peels and apple pomace. INS 440, ADI is Not Limited (Quantum Satis), the global gold standard gelling agent for jams, jellies, and fruit spreads.
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.
