Stevioside-Rebaudioside D Complex Solubility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rebaudioside D has low solubility in water, making it difficult to prepare beverage concentrates and beverages with sufficient sweetness and organoleptic properties, as only about 300 to 450 ppm can be solubilized at 23°C after extended stirring, which is impractical for commercial production.
Innovation Solution
Combining rebaudioside D with stevioside in various ratios in an aqueous solution at room or elevated temperatures to create a stevioside/rebaudioside D complex, significantly increasing rebaudioside D solubility up to 10,000 to 25,000 ppm, allowing for higher concentration solutions to be prepared in reasonable timeframes suitable for commercial manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If rebaudioside D is combined with stevioside in various ratios in an aqueous solution, then rebaudioside D solubility is significantly increased (50 to 125-fold), but the complexity of the composition increases
Solution Approach 1:
The patent combines rebaudioside D with stevioside to form a composite sweetening composition. This composite material approach allows the beneficial solubility enhancement from stevioside to be harnessed while maintaining the desirable taste profile of rebaudioside D, achieving both improved solubility and acceptable product quality
Solution Approach 2:
The patent optimizes the ratio parameters of stevioside to rebaudioside D in the composition to achieve maximum solubility enhancement. By carefully controlling these compositional parameters, the patent achieves 50 to 125-fold increases in solubility while managing the complexity through defined ratio ranges
2Quantity of substance
If rebaudioside D is used at higher concentrations to provide desired sweetness, then sweetness level improves, but solubility limitations prevent achieving sufficient concentrations in practical timeframes
Solution Approach 1:
Stevioside acts as an intermediary substance that facilitates the dissolution of rebaudioside D. By introducing stevioside into the system, the patent creates a medium that enables much higher concentrations of rebaudioside D to be achieved rapidly, without requiring extended stirring times
Solution Approach 2:
The patent prepares stevioside/rebaudioside D complex compositions in advance that are pre-formulated to provide rapid solubility enhancement. This preliminary preparation of optimized compositions allows for quick dissolution and immediate achievement of target sweetness concentrations in commercial production
