Comparing:
E290: Carbon Dioxide (Carbonation & MAP Gas)
E460: Microcrystalline Cellulose (MCC / Dietary Bulking)
E290 (Carbon Dioxide / CO2) is an authorized food additive functioning as a carbonating gas, modified atmosphere packaging (MAP) preservative, and cryogenic freezing propellant. INS 290, ADI is Not Limited (Quantum Satis).
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.
