Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Steviol glycosides exhibit poor aqueous solubility, leading to challenges in manufacturing sweetener compositions and resulting in unstable solutions that precipitate over time, affecting the appearance, taste, and shelf-life of sweetened products.
Innovation Solution
A method involving a mixture of rebaudioside M and rebaudioside A at specific weight ratios (0.2 to 0.9) in an aqueous solvent, heated to at least 70°C for a specified duration, to achieve a stable and highly concentrated steviol glycoside composition with a dissolved content of at least 5 wt %.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional steviol glycosides are used in aqueous solutions, then the solutions can be prepared, but the solubility is poor and precipitation occurs over time
Solution Approach 1:
The patent combines rebaudioside M and rebaudioside A in specific weight ratios (0.2 to 0.9) to create a synergistic effect that dramatically improves solubility. This merging of two components with complementary properties allows the mixture to achieve higher dissolved concentrations while maintaining stability, resolving the contradiction between solubility and stability.
Solution Approach 2:
The patent changes the concentration parameter by achieving at least 5 wt % dissolved steviol glycoside content, which is five times higher than conventional formulations. This parameter change is made possible through the specific combination of rebaudioside M and A, allowing the system to maintain both high concentration and stability simultaneously.
2Quantity of substance
If higher concentrations of steviol glycosides are dissolved, then the sweetness intensity increases, but the solutions become unstable and precipitate forms
Solution Approach 1:
By merging rebaudioside M and rebaudioside A in optimized ratios, the patent creates a stable complex that prevents precipitation even at high concentrations. The combination effect allows the system to achieve both high dissolved concentration (at least 5 wt %) and long-term stability without the formation of precipitates.
Solution Approach 2:
The patent creates a composite steviol glycoside system combining rebaudioside M and A with specific weight ratios. This composite formulation exhibits superior solubility and stability properties compared to individual components, enabling high concentration solutions that remain stable over time without precipitating.
3Quantity of substance
If freeze drying or spray drying is used to improve solubility, then some dissolution is achieved, but the solutions remain unstable and show murkiness
Solution Approach 1:
The patent merges rebaudioside M and rebaudioside A in specific ratios to achieve a fundamental improvement in solubility mechanism. This combination allows the system to dissolve at least 5 wt % steviol glycosides while maintaining clarity and stability, overcoming the limitations of conventional drying methods that produce unstable, murky solutions.
4Quantity of substance
If elevated temperatures are used to improve solubility, then dissolution is enhanced, but thermal degradation of steviol glycosides occurs
Solution Approach 1:
The patent combines rebaudioside M and rebaudioside A to achieve enhanced solubility through a mechanism that does not require high temperatures. This merging creates a synergistic effect that improves dissolution at lower temperatures, thereby avoiding thermal degradation while still achieving at least 5 wt % dissolved concentration.
Solution Approach 2:
The patent changes the approach to solubility enhancement by using compositional modification rather than temperature increase. The specific weight ratio combination of rebaudioside M and A enables high dissolution concentrations without relying on elevated temperatures, thus avoiding thermal degradation of the steviol glycoside compounds.
