E460: Microcrystalline Cellulose (MCC / Dietary Bulking) vs. E621: Monosodium Glutamate (MSG / Umami Flavor Enhancer)
Comparing 2 standards across 13 specifications. 13 key differences identified.
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.
Monosodium Glutamate (E621, MSG, C5H8NO4Na) is the sodium salt of L-glutamic acid produced via Corynebacterium glutamicum sugar fermentation, activating human T1R1/T1R3 heterodimer umami taste receptors to enhance savory mouthfeel.
