Demand for lower-sugar and sugar-free products continues to influence food and beverage formulation. Public-health policy, front-of-pack communication and taxes on sugar-sweetened beverages in a number of markets add further pressure to reduce added sugar.
High-intensity sweeteners can support this objective, but their value extends beyond calorie reduction.
Because these ingredients deliver high sweetness at low dosage, they can reduce the cost contribution of the sweetening system, particularly in liquid products such as beverages and sauces where replacing sugar does not always require a large amount of bulking material.
Sugar-based beverage production may require screening, dissolving, syrup preparation, storage and transfer. High-intensity sweeteners can reduce the mass of material that has to be handled and simplify some of these operations.
Logistics can also change substantially: a sweetener with approximately 200 times the sweetness of sucrose is required in a far smaller quantity than sugar, although the complete recipe still needs to account for solids, mouthfeel and process requirements.
Sucrose can contribute fermentable substrate in some systems. Many high-intensity sweeteners are not readily metabolized by common spoilage microorganisms. This can support formulation strategy, but it does not replace proper preservation, hygiene or microbiological validation.
Many high-intensity sweeteners contribute little or no energy at their normal use levels and do not produce the same glycemic response as sucrose. They are also generally non-cariogenic. Any nutrition or health claim must, however, follow the rules of the market where the finished product is sold.
Common applications include soft drinks, energy drinks, sauces, fermented dairy products, confectionery, snacks and pharmaceutical or nutraceutical formats. The optimal system differs by matrix because acidity, heat treatment, flavor profile and solids content all affect performance.
Choosing a sweetener involves more than comparing sweetness potency. WM considers target cost, sweetness onset and decay, aftertaste, synergy between ingredients, interaction with flavor, stability during processing and storage, and applicable legislation.
The objective is a complete sensory solution that reaches the required sugar reduction without sacrificing the product’s identity.
