Comparing:
E224: Potassium Metabisulfite (Campden Salt)
E960: Steviol Glycosides (Reb-A / Stevia Extract)
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.
E960 (Steviol Glycosides / Rebaudioside A) is a natural zero-calorie sweetener water-extracted from the leaves of the Stevia plant (Stevia rebaudiana). INS 960a, ADI is 4 mg/kg bw/day (as steviol equivalents), providing 250–350x sucrose sweetness.
