This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,856,974.

Background and Problem Solved

The original patent disclosed a process for preparing highly soluble individual or combined sweet glycosides from a Stevia rebaudiana Bertoni plant extract, but the solubility of Rebaudioside A remains a significant limitation. The new invention addresses this limitation by introducing novel methods and systems to increase the solubility of Rebaudioside A, making it more efficient and commercially viable.

Novelty and Inventive Step

The new invention introduces novel methods and systems to increase the solubility of Rebaudioside A, including temperature control, ultrasonic energy, and solubility-enhancing agents, which are not disclosed in the original patent. The inventive step lies in the combination of these methods and systems to achieve improved solubility and commercial viability.

Alternative Embodiments and Variations

Other embodiments of the invention may include using different solvents, varying the ratio of solvent to crystalline Rebaudioside A powder, or incorporating additional steps to further enhance solubility. The system and method can also be adapted for use with other sweet glycosides or plant extracts.

Potential Commercial Applications and Market

The invention has significant commercial potential in the food and beverage industry, particularly in the production of low-calorie sweeteners and sugar substitutes. The improved solubility and efficiency of the system and method make it an attractive solution for manufacturers and consumers alike.
