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 for Highly Soluble Stevia Sweetener addressed the issue of Rebaudioside A's polymorphism, but its methods were limited by scalability and solubility rates. The new invention overcomes these limitations by introducing modular, large-scale production capabilities and optimized solvent systems, enabling the creation of novel sweetener compositions with enhanced bioavailability and tailored flavor profiles.

Novelty and Inventive Step

The new claims introduce a synergistic blend of glycosides, nanotechnology-based encapsulation, microemulsion technology, and tailored solvent systems, which are not obvious from the original patent. The inventive step lies in the integration of these cutting-edge technologies to create a paradigm-shifting stevia sweetener platform.

Alternative Embodiments and Variations

Alternative embodiments may include the use of different nanoparticle materials, varying solvent systems, or alternative mixing technologies. Variations may include the development of sweetener compositions tailored to specific food and beverage applications, such as beverages, baked goods, or confectionery.

Potential Commercial Applications and Market

The Next-Generation Stevia Sweetener Platform has significant commercial potential in the food and beverage industry, particularly in the low-calorie sweetener market. Target industries include beverage manufacturers, food processors, and pharmaceutical companies seeking to develop novel sweetener compositions for various applications.
