Comparing:
E412: Guar Gum (Cold-Soluble Galactomannan)
E951: Aspartame (Dipeptide Sweetener / 200x)
E412 (Guar Gum) is a natural galactomannan hydrocolloid extracted from guar beans (Cyamopsis tetragonoloba). INS 412, ADI is Not Limited (Quantum Satis), boasting 8x the thickening power of cornstarch and hydrating completely in cold water.
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.
