E471: Mono- & Diglycerides of Fatty Acids (Bread Softener) vs. E631: Disodium Inosinate (IMP Meat Umami Synergist)
Comparing 2 standards across 10 specifications. 10 key differences identified.
E471 is an authorized food emulsifier composed of glycerol esterified with one or two fatty acid chains (glycerol monostearate / monooleate). INS 471, ADI is Not Limited (Quantum Satis), globally recognized as the ultimate crumb softener and amylose complexing agent in bakery.
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.
