Comparing 2 standards across 11 specifications. 11 key differences identified.
Comparing:
E338: Phosphoric Acid (Cola Acidulant)
E951: Aspartame (Dipeptide Sweetener / 200x)
E338 (Phosphoric Acid / H3PO4) is a mineral inorganic acid providing a uniquely dry, tangy, astringent sourness. INS 338, group ADI is 40 mg/kg bw/day (as phosphorus), the quintessential acidulant in cola beverages and processed cheeses.
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.
