E338: Phosphoric Acid (Cola Acidulant) vs. E955: Sucralose (Splenda / 600x Heat-Stable Sweetener)
Comparing 2 standards across 12 specifications. 12 key differences identified.
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.
E955 (Sucralose) is a chlorinated disaccharide synthesized by selective chlorination of sucrose (replacing three hydroxyl groups with chlorine atoms). INS 955, ADI is 15 mg/kg bw/day, providing 600x sugar sweetness with zero calories and full heat stability for baking.
