E407: Carrageenan (Dairy Stabilizer Hydrocolloid) vs. E631: Disodium Inosinate (IMP Meat Umami Synergist)
Comparing 2 standards across 10 specifications. 10 key differences identified.
E407 (Carrageenan) is a high-molecular-weight sulfated polygalactan extracted from red edible seaweeds (Chondrus crispus / Irish Moss). INS 407, ADI is 75 mg/kg bw/day, famed for stabilizing cocoa suspension in chocolate milk via kappa-casein binding.
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.
