Arabinoxylan Composition Extraction for Prebiotic Efficacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fiber compositions derived from plant sources often fail to meet the recommended daily intake of fiber and may not provide the desired prebiotic effects due to variations in molecular weight and polyphenol content.
Innovation Solution
The development of compositions containing predominantly arabinoxylan with a molecular weight of 5500-6000 Da, along with specific contents of carbohydrate polymers, polyphenols, and other components, to enhance prebiotic effects and nutritional value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional plant-based fiber compositions are extracted, then fiber content is provided, but the molecular weight varies and prebiotic effects are insufficient
Solution Approach 1:
The patent applies parameter changes by controlling extraction conditions (temperature, pH, solvent composition) to obtain arabinoxylan with specific molecular weight ranges (5500-6000 Da). By adjusting these parameters during extraction, the process consistently produces arabinoxylan within the target molecular weight range, ensuring both prebiotic efficacy and manufacturing precision
Solution Approach 2:
The patent replaces conventional mechanical extraction methods with enzymatic hydrolysis using specific enzymes (xyloglucanase, arabinofuranosidase, beta-glucosidase) to precisely control molecular weight. This biochemical approach substitutes mechanical force with enzyme-catalyzed reactions that selectively cleave glycosidic bonds to achieve the desired molecular weight distribution
2Quantity of substance
If arabinoxylan is extracted from plants like wheat and corn, then fiber composition is obtained, but the composition contains many impurities (carbohydrate polymers, proteins, ash)
Solution Approach 1:
The patent applies extraction by using selective solvents and filtration methods to separate arabinoxylan from impurities. The process extracts arabinoxylan into solution while leaving behind carbohydrate polymers, proteins, and ash as insoluble residues, then precipitates and purifies the arabinoxylan to achieve >88% purity
Solution Approach 2:
The patent applies local quality by treating different components of the plant material differently during extraction. Specific enzymes target and modify only certain glycosidic bonds in arabinoxylan while leaving other components largely unaffected, and selective precipitation conditions affect only arabinoxylan, achieving high purity without excessive processing
3Reliability
If conventional extraction methods are used, then fiber composition is obtained, but polyphenol content is insufficient for desired health effects
Solution Approach 1:
The patent applies merging by combining arabinoxylan extraction with polyphenol co-extraction using the same solvent system and processing conditions. The extraction process simultaneously recovers both arabinoxylan and polyphenols, which are then concentrated together to achieve the desired ratio and total content for optimal health benefits
