Comparing:
E415: Xanthan Gum (Pseudoplastic Hydrocolloid Thickener)
E950: Acesulfame Potassium (Ace-K / 200x Sweetener)
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.
E950 (Acesulfame K / Ace-K) is a calorie-free, heat-stable synthetic potassium salt sweetener approximately 200 times sweeter than sucrose. INS 950, ADI is 9 mg/kg bw/day, famous for blending with sucralose and aspartame to produce sugar-identical taste curves.
