Comparing:
E224: Potassium Metabisulfite (Campden Salt)
E460: Microcrystalline Cellulose (MCC / Dietary Bulking)
E224 (Potassium Metabisulfite / K2S2O5) is a white crystalline powder releasing 57.6% sulfur dioxide by weight when dissolved in acidic liquids. INS 224, ADI is 0.7 mg/kg bw/day, the premier sanitizing and stabilizing agent in commercial winemaking.
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.
