Comparing:
E635: Disodium 5'-Ribonucleotides (I+G Blend)
E951: Aspartame (Dipeptide Sweetener / 200x)
E635 (I+G) is a standardized 50/50 co-crystallized blend of disodium inosinate (E631) and disodium guanylate (E627). INS 635, ADI is Not Specified, serving as the commercial standard umami booster in global food manufacturing.
E951 (Aspartame) is a methyl ester of the aspartic acid/phenylalanine dipeptide yielding ~200x the sweetness of sucrose. INS 951, ADI is 40 mg/kg bw/day, the historic sweetener in Diet Coke and tabletop sweetener packets.
