Sweeteners, especially those derived from stevia, often face solubility challenges that hinder their effectiveness in various applications. This issue becomes particularly pressing in beverages, where poor solubility can lead to uneven sweetness and undesirable textures. As consumer demand for natural, low-calorie sweeteners grows, the need for solutions that enhance solubility without compromising taste becomes increasingly critical.

Professionals in the food and beverage industry grapple with the delicate balance of maintaining sweetness while ensuring complete dissolution. Traditional methods fall short, often resulting in sedimentation or a lack of uniformity in product formulations. The pursuit of solubility has led to exploring new methods and compositions that address these persistent challenges.

This page compiles a range of strategies and compositions aimed at enhancing the solubility of stevia-based sweeteners. From synergistic blends to natural emulsifiers and advanced solubilization processes, these solutions promise to improve the consistency and sensory profile of sweetened products. By integrating these approaches, professionals can achieve more reliable and appealing results in their formulations.

1. Steviol Glycoside Mixture with Soluble Rebaudioside D and Disrupted Crystal Structure

PepsiCo, Inc., 2023

A mixture of stevioside and rebaudioside D that provides a complete solubility of rebaudioside D in water. This allows for a synergistic blend of steviol glycosides with improved taste over rebaudioside A alone. The stevioside disrupts rebaudioside D's crystal structure, lowers the energy required to dissolve it in water, and masks its taste. This enables commercial use of rebaudioside D as a sweetener.
