Comparing:
E501: Potassium Carbonate (Potash / Alkaline Noodle Salt)
E950: Acesulfame Potassium (Ace-K / 200x Sweetener)
E501 (Potassium Carbonates / K2CO3) is an inorganic alkaline mineral salt. INS 501(i), ADI is Not Limited (Quantum Satis), used as the key 'Kansui' alkaline agent in Japanese ramen noodles and in the Dutch processing of cocoa powder.
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.
