E631: Disodium Inosinate (IMP Meat Umami Synergist) vs. E950: Acesulfame Potassium (Ace-K / 200x Sweetener)
Comparing 2 standards across 11 specifications. 11 key differences identified.
E631 (Disodium 5'-Inosinate / IMP) is the sodium salt of inosinic acid, a purine nucleotide naturally found in aged beef, katsuobushi bonito flakes, and cured meats. INS 631, ADI is Not Specified, multiplying glutamate umami flavor.
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.
