E406: Agar-Agar (Seaweed Hydrocolloid Gel) vs. E460: Microcrystalline Cellulose (MCC / Dietary Bulking)
Comparing 2 standards across 10 specifications. 9 key differences identified.
E406 (Agar-Agar) is a natural sulfated galactan polysaccharide hydrocolloid extracted from red algae seaweeds (Rhodophyta). INS 406, ADI is Not Limited (Quantum Satis), forming firm, brittle thermoreversible gels with huge hysteresis (melts at 85°C, sets at 35°C).
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.
