Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional extraction methods are used to obtain mogrosides from Luo han guo, then the extraction process is simple and quick, but the extract contains multiple impurities that affect color, smell and taste profile
Solution Approach 1:
The extraction process is divided into multiple sequential steps: initial extraction of mogrosides, followed by fractionation using silica gel chromatography, and further purification using reverse phase chromatography. Each step separates specific components, progressively removing impurities while maintaining extraction efficiency.
Solution Approach 2:
Specific impurity components are selectively removed from the mogroside extract through chromatographic separation. The silica gel column removes polar impurities, while the reverse phase column removes non-polar impurities, effectively extracting harmful substances while retaining the desired mogrosides.
2Reliability
If high concentrations of mogrosides are used to enhance sweetness, then the sweetness effect is strong, but the flavor recognition threshold is exceeded causing undesirable taste
Solution Approach 1:
The mogroside mixture is engineered to have specific compositional characteristics where certain mogrosides (particularly mogroside V and mogroside III) are present in higher proportions. This localized optimization of the compositional quality provides strong sweetness while the purified profile prevents off-flavors that would occur with higher concentrations of crude extract.
Solution Approach 2:
The concentration of individual mogroside components is precisely controlled within specific ranges. The purified extract maintains mogroside V at 40-60% and mogroside III at 20-40%, optimizing the sweetness-to-flavor-threshold ratio to deliver potent sweetness without exceeding the flavor recognition threshold.
3Object-affected harmful factors
If multiple chromatography steps are used to purify mogrosides, then the purity and organoleptic properties are improved, but the process complexity and time increase
Solution Approach 1:
The extraction process begins with pre-treatment of the Luo han guo material to optimize mogroside release before chromatography. The initial extraction conditions are carefully controlled to maximize mogroside solubility and minimize co-extraction of impurities, reducing the burden on subsequent purification steps.
Solution Approach 2:
Silica gel and reverse phase chromatography media serve as intermediary substances that selectively interact with different components of the extract. These intermediaries facilitate the separation of mogrosides from impurities through differential adsorption, enabling high purification without requiring excessively complex processing.
4Stability of the object's composition
If certain mogrosides like mogroside III and mogroside IIE are present in the extract, then the extract contains natural mogroside composition, but these specific mogrosides can be tasteless or even bitter
Solution Approach 1:
The mogroside composition is optimized to have localized high concentrations of sweet-tasting mogrosides (mogroside V at 40-60% and mogroside IV at 10-30%) while maintaining a more balanced presence of other mogrosides. This compositional quality distribution ensures the dominant sweet flavor masks any bitterness from minor components.
Solution Approach 2:
The purified mogroside extract is formulated as a composite mixture of multiple mogroside compounds in specific ratios. This composite composition leverages the synergistic effect where the high concentration of sweet mogrosides dominates the flavor profile, while the presence of other mogrosides in controlled amounts maintains natural composition characteristics without introducing significant bitterness.
