Stevia vs Sucralose vs Aspartame: Comparison

The Sugar-Free Beverage Revolution

The sugar-free beverage market is experiencing explosive growth in Canada. Consumers want sweet taste without the calories, and manufacturers must find the sweetener — or combination of sweeteners — that most faithfully reproduces the taste profile of sugar.

This guide compares the four most widely used sweeteners in the Canadian beverage industry: stevia, sucralose, aspartame, and acesulfame-K.

Stevia (Reb A and Reb M)

Reb A (Stevia Reb A)

  • Sweetness: 200-300x sugar
  • Taste: sweet with notable bitter/licorice aftertaste, especially at higher concentrations
  • Price: moderate — most common and affordable stevioside
  • Best for: beverages where taste can be masked by strong flavors (citrus, mint)

Reb M (Stevia Reb M)

  • Sweetness: 200-350x sugar
  • Taste: much cleaner than Reb A, minimal aftertaste
  • Price: higher — more complex extraction
  • Best for: premium beverages where "natural" taste is a key selling point

Sucralose

Sucralose is the beverage industry's sweetener of choice.

  • Sweetness: 600x sugar
  • Taste: very close to sugar, quick onset, no metallic aftertaste
  • Stability: excellent — heat, acidic pH, and long-term storage
  • Best for: any sugar-free beverage — the universal standard

Aspartame

Aspartame is one of the most studied sweeteners in the world, approved by Health Canada, the FDA, and the WHO.

  • Sweetness: 200x sugar
  • Taste: closest to sugar in terms of pure taste profile
  • Stability: limited heat stability (degrades above 80°C)
  • Price: most affordable high-intensity sweetener

Acesulfame-K

Acesulfame-K is rarely used alone. Its strength lies in creating powerful synergies with other sweeteners.

  • Sweetness: 200x sugar
  • Best for: combinations — never alone

Popular Combinations

  • Sucralose + Ace-K (60:40) — industry standard for sugar-free beverages
  • Aspartame + Ace-K (50:50) — used in Coca-Cola Zero and Pepsi Zero
  • Stevia + Ace-K — reduces stevia aftertaste
