Sucralose
Sucralose is an intense, high‑potency, non‑nutritive sweetener, about 600 times sweeter than sucrose. It is stable at elevated temperatures and across a wide pH range. It does not significantly affect the caloric value of the final product and does not cause changes in color or odor during processing and storage. It is typically used at very low dosages, either alone or in combination with other sweeteners and bulking agents.
Source and Production
Sucralose is produced by chemical modification of the sucrose molecule, in which three hydroxyl groups are replaced with chlorine atoms. This transformation yields very high sweetness with minimal metabolic response and excellent stability in aqueous solutions. The starting raw material is refined sugar, while the final product is a white, crystalline powder with a neutral odor, suitable for use in a wide variety of food matrices.
Product Variants
- Pure sucralose (powder) – highly concentrated, intended for industrial use and precise dosing.
- Microgranulated sucralose – improved solubility and dispersion, particularly suitable for instant beverages and dry mixes.
- Sucralose blends with bulking agents (e.g. maltodextrin, erythritol, polydextrose) – used where more bulk, texture, or a sugar‑like mouthfeel is required, especially in powdered and bakery products.
Applications in the Food Industry
Soft Drinks and Beverages
Used in carbonated and still drinks, syrups, energy and functional beverages, powdered instant drinks, and flavored waters. Sucralose:
- Provides high sweetness with reduced or zero energy content
- Remains chemically stable, so taste stays consistent throughout shelf life without development of off‑flavors
Dairy and Fermented Dairy Industry
Applied in yogurts, protein drinks, dairy desserts, puddings, and ice creams. Sucralose:
- Withstands pasteurisation and UHT treatment
- Does not negatively affect starter cultures in fermented products
- Is suitable for reduced‑sugar or no‑added‑sugar products while maintaining a pleasant sweet profile
Bakery and Confectionery Industry
Thanks to its thermal stability, sucralose is used in biscuits, cakes, sponge products, fillings, toppings, chewing gum, and hard candies. In combination with bulking agents and polyols it can provide:
- Desired volume and texture in diet and “light” variants
- Sweetness without the caramelisation effect typical of sucrose
Dietetic and Functional Products
Common in protein bars, instant protein drinks, powdered supplements, vitamin–mineral blends, and diet shakes. Sucralose:
- Masks bitter or metallic notes of active ingredients
- Improves taste without increasing caloric value or affecting glycaemic index
Benefits of Using Sucralose
- Very high sweetness at extremely low dose, with easy formulation adjustment
- Low calorie contribution and minimal impact on glycaemic index – ideal for “zero sugar” and “light” claims
- High thermal and pH stability, with no degradation or loss of sweetness during processing and storage
- Neutral taste with minimal off‑notes and good synergy with other sweeteners
- Flexible use in a wide range of food matrices, including beverages, dairy, bakery, confectionery, and dietetic products
