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. 11,856,972.

Background and Problem Solved

The original patent disclosed a process for preparing compositions comprising steviol glycosides, but it had limitations in terms of sweetness level, flavor profile, and solubility. This invention addresses these limitations by introducing proprietary cultivars, optimized extraction processes, and solubility-enhancing agents to produce high-quality stevia extracts.

Novelty and Inventive Step

The novelty of this invention lies in the introduction of proprietary cultivars, optimized extraction processes, and solubility-enhancing agents, which provide a significant improvement over the original patent. The inventive step is the combination of these elements to produce high-quality stevia extracts with enhanced sweetness level, flavor profile, and solubility.

Alternative Embodiments and Variations

Alternative embodiments of the invention include using different Stevia rebaudiana cultivars, varying the extraction process parameters, and incorporating different solubility-enhancing agents. Variations of the invention may include using different types of sweeteners or flavor enhancers, or applying the invention to different industries such as pharmaceuticals or cosmetics.

Potential Commercial Applications and Market

The invention has significant commercial potential in the food and beverage industry, as well as in the pharmaceutical and cosmetics industries. The improved stevia extracts can be used as natural sweeteners and flavor enhancers, providing a competitive advantage to companies that adopt this technology. The market for natural sweeteners is growing rapidly, and this invention is well-positioned to capitalize on this trend.
