Sugar Alternatives

In recent years, the quest for healthier dietary choices has prompted a surge in the exploration of sugar alternatives. Sugar alternatives, also known as sugar substitutes or sweeteners, encompass a variety of compounds engineered to replicate the sweetness of sucrose. These compounds belong to different chemical classes, including polyols (e.g., xylitol, erythritol), vegetable fibers, high-intensity sweeteners (e.g., aspartame, saccharin), and natural sweeteners (e.g., stevia, monk fruit extract). The distinctive taste profiles of these alternatives result from their ability to activate sweet taste receptors on the tongue, mimicking the sensory experience of sugar without the associated caloric content plus giving body and tecture to the confections.

Polyols, or sugar alcohols, such as xylitol and erythritol, are a class of sugar alternatives characterized by their partial sugar-like structure. These compounds are derived from natural sources like fruits or synthesized through processes such as hydrogenation or fermentation. Polyols provide sweetness with fewer calories than sucrose and are known for their reduced impact on blood sugar levels. Notably, they exhibit a cooling effect when consumed, and their low caloric content makes them popular in sugar-free and diabetic-friendly products.

High-intensity sweeteners, exemplified by aspartame and saccharin, are synthetically produced compounds designed to impart sweetness at levels much higher than sucrose. These sweeteners are intensely sweet, allowing for minimal usage in formulations. They contribute negligible or no calories to food products, making them suitable for those seeking calorie reduction or managing conditions like diabetes. While some high-intensity sweeteners may have a distinct aftertaste at high concentrations, meticulous formulation can mitigate this effect.

Natural sweeteners, such as stevia and monk fruit extract, are derived from plant sources and have gained popularity as alternatives to artificial sweeteners. These sweeteners contain compounds that deliver sweetness without the caloric impact of sugar. Stevia, for example, contains steviol glycosides, while monk fruit extract contains mogrosides. Natural sweeteners are often lauded for their plant-based origins, and they may offer additional health benefits beyond calorie reduction, such as potential antioxidant properties. Their sweetness profiles vary, providing a diverse array of options for formulators aiming to balance taste and natural appeal.

Vegetable fibers, such as corn or tapioca fiber, have been recently utilized as substitutes for sugar as bulking agents in various food products.  With their ability to mimic the texture and functionality of sugar while offering additional nutritional benefits, such as increased fiber content, these plant-based alternatives present a promising solution for manufacturers seeking to meet the evolving preferences of health-conscious consumers

Source and Processing

The sources of sugar alternatives vary widely. Natural sweeteners like stevia and monk fruit are derived from the leaves and fruits of the respective plants. Extraction typically involves crushing, soaking, and purification processes to isolate the sweet compounds.

Polyols are often obtained from natural sources like fruits, but commercial production involves fermentation or hydrogenation.

High-intensity sweeteners are chemically synthesized, with precise methods to ensure purity and sweetness

Fibers are predominantly sourced from plants, including fruits, vegetables, grains, and legumes. The extraction process involves mechanical separation, often followed by purification methods. In some cases, fibers are also obtained from seaweed and microbial sources. The production process aims to retain the structural and functional properties of the fibers, ensuring their effectiveness in confections.

Main function in Confections

The primary function of sugar alternatives in confections is to impart sweetness without the caloric burden associated with traditional sugars and provide the body for a confection. They serve as crucial components in the production of sugar-free or reduced-sugar products, catering to the growing demand for healthier alternatives without compromising taste or texture.


Hygroscopicity: Sugar alternatives exhibit varying degrees of hygroscopicity, influencing their moisture absorption capacity. This property is crucial in determining the texture and shelf stability of confections.

Crystallization: Polyols such as xylitol and erythritol display reduced crystallization tendencies compared to sucrose, impacting the texture and mouthfeel of confectionery products.

Solubility: The solubility of sugar alternatives in water influences their ease of incorporation into formulations. Most alternatives exhibit good solubility, contributing to their versatility in diverse food applications.

Shelf stability: Sugar alternatives contribute to the shelf stability of confections by influencing water activity and preventing microbial growth. This is especially pertinent in sugar-free products that require extended shelf life.


In the United States, the Food and Drug Administration (FDA) regulates sugar alternatives. Each sweetener undergoes rigorous scrutiny for safety and efficacy before receiving approval for use in food and beverages. The Code of Federal Regulations (CFR) Title 21 details the specific regulations governing sweeteners, including acceptable daily intake (ADI) levels and labeling requirements.
