Comparing:
E501: Potassium Carbonate (Potash / Alkaline Noodle Salt)
E965: Maltitol (Sugar Alcohol / 90% Sweetness)
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.
E965 (Maltitol) is a disaccharide polyol sugar alcohol produced by hydrogenation of maltose derived from cornstarch. INS 965(i), ADI is Not Specified (Excessive consumption may have laxative effect), delivering 90% the sweetness of sugar with 2.1 kcal/g.
