Comparing:
E251: Sodium Nitrate (Chile Saltpeter / Slow Curing)
E955: Sucralose (Splenda / 600x Heat-Stable Sweetener)
E251 (Sodium Nitrate / NaNO3) is an inorganic salt serving as a slow-release chemical reservoir of nitrite in long-aged cured meats and hard cheeses. INS 251, ADI is 3.7 mg/kg bw/day, enzymatically reduced into nitrite over months of curing.
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.
