E415: Xanthan Gum (Pseudoplastic Hydrocolloid Thickener) vs. E960: Steviol Glycosides (Reb-A / Stevia Extract)
Comparing 2 standards across 17 specifications. 17 key differences identified.
Xanthan gum (E415) is a high-molecular-weight microbial exopolysaccharide produced by Xanthomonas campestris fermentation, renowned for extreme pseudoplastic shear-thinning rheology, freeze-thaw stability, and gluten-free dough structural binding.
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.
