Comparing:
E440: Pectin (Citrus & Apple Jam Gelling Fiber)
E951: Aspartame (Dipeptide Sweetener / 200x)
E440 (Pectin) is a complex heteropolysaccharide rich in alpha-(1->4)-linked D-galacturonic acid extracted from citrus peels and apple pomace. INS 440, ADI is Not Limited (Quantum Satis), the global gold standard gelling agent for jams, jellies, and fruit spreads.
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.
