Lingonberry Extract Production via Segmented Acid-Alcohol Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lingonberry extract methods are inefficient in extracting effective ingredients, limited to external use, and waste materials, with a need for a safer and more effective extract with broader application fields.
Innovation Solution
A method involving the extraction of lingonberry fruit using aqueous acid or aqueous alcohol at normal or lower temperatures, followed by filtration, purification with resin, and chromatography to produce extracts rich in anthocyanidin, procyanidin, and resveratrol, which are then combined to create three types of lingonberry extracts with varying compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional extraction methods using alcohol-water solution are used, then the extraction process is simple, but the effective ingredients are not extracted sufficiently and materials are wasted
Solution Approach 1:
The extraction process is divided into multiple stages: first extraction with aqueous acid, second extraction with aqueous alcohol, followed by separation into different fractions (first fraction rich in anthocyanidin, second fraction rich in resveratrol). This segmentation allows comprehensive extraction of different effective ingredients from lingonberry materials that would be lost in conventional single-step extraction.
Solution Approach 2:
The patent changes extraction parameters by using aqueous acid at normal temperature for the first extraction, then aqueous alcohol at normal or lower temperature for the second extraction. This parameter optimization enables complete extraction of effective ingredients including anthocyanidin, procyanidin, and resveratrol, eliminating material waste while maintaining extraction simplicity.
2Adaptability or versatility
If mixed raw materials of lingonberry leaves and fruits are used, then the extract contains more components, but the usage is limited and the extract is complicated
Solution Approach 1:
The patent extracts and isolates specific effective ingredients (anthocyanidin, procyanidin, resveratrol) from the complex mixture of lingonberry leaves and fruits. By taking out only the beneficial components through controlled extraction and separation processes, the patent creates simplified extracts with defined compositions that can be applied to multiple purposes including cosmetic, pharmaceutical, and food industries.
Solution Approach 2:
The patent produces multiple types of lingonberry extracts with different compositions (first fraction rich in anthocyanidin, second fraction rich in resveratrol, and combined extracts) that can be universally applied across cosmetic, pharmaceutical, and food sectors. This multi-functionality expands application range while maintaining manageable composition complexity through standardized extraction protocols.
3Reliability
If conventional extraction methods are used, then the process is straightforward, but the extract has limited efficacy and safety concerns
Solution Approach 1:
The patent performs preliminary actions by pre-treating lingonberry materials with aqueous acid extraction before the main aqueous alcohol extraction. This preliminary step prepares the materials by releasing bound effective ingredients, making the subsequent extraction more efficient and ensuring the final extract has proven safety and efficacy while maintaining manufacturing simplicity through a systematic multi-step process.
