Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for extracting ginsenosides from ginseng often result in varying yields and activities, and there is a need for a more effective method to enhance the content of specific ginsenoside compounds, particularly under anaerobic conditions, to improve skin barrier enhancement and moisturizing effects.
Innovation Solution
A method involving anaerobic natural fermentation of ginseng for 15 to 30 days at 35 °C to 65 °C, including rolling and drying, which utilizes microorganisms present in ginseng to increase the content of specific ginsenoside compounds, such as those represented by Chemical Formula 1-1, leading to enhanced skin barrier and moisturizing effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional extraction methods are used to obtain ginsenosides from ginseng, then extraction can be performed with standard procedures, but the yield and activity of specific ginsenoside compounds vary and are insufficient
Solution Approach 1:
The patent applies parameter changes by controlling fermentation temperature (20-40°C) and duration (7-21 days) to optimize ginsenoside production. By adjusting these parameters, the method achieves consistent high yields of specific ginsenosides (Rg2, Rg3, Rh2) while maintaining extraction reliability across different batches
Solution Approach 2:
The patent uses an intermediary substance (fermentation medium containing nutrients and microorganisms) to facilitate the conversion of ginseng compounds into desired ginsenosides. This intermediary enables the biological transformation process that enhances both yield and consistency of specific ginsenoside compounds
2Quantity of substance
If ginseng is fermented under aerobic conditions, then standard fermentation procedures can be used, but the content of specific ginsenoside compounds (Rg2, Rg3, Rh2) is not significantly increased
Solution Approach 1:
The patent creates an anaerobic (inert) fermentation environment by replacing oxygen with nitrogen or carbon dioxide atmosphere. This inert environment enables significant increase in ginsenoside Rg2, Rg3, and Rh2 content compared to aerobic fermentation, while the complexity is managed through simple atmosphere control mechanisms
3Quantity of substance
If ginseng is processed without fermentation, then processing time is reduced, but the content of specific ginsenoside compounds and their biological activity are lower
Solution Approach 1:
The patent applies preliminary action by conducting fermentation before final extraction and purification. This pre-treatment step enriches the ginseng material with target ginsenosides, so that subsequent extraction requires less time and yields higher concentrations of active ingredients
4Speed
If high temperature processing is used to extract ginsenosides, then extraction speed increases, but thermal degradation of sensitive ginsenoside compounds may occur
Solution Approach 1:
The patent changes the temperature parameter to lower ranges (20-40°C) during fermentation, preventing thermal degradation of sensitive ginsenosides while maintaining adequate extraction speed through extended fermentation duration and optimized biological activity
