Allulose Precursor Composition for Simplified Thermal Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of precursor compositions for preparing allulose, a low-calorie saccharide, which is difficult to synthesize or purify using conventional chemical or enzymatic methods.
Innovation Solution
A novel allulose disaccharide precursor, specifically 6-O-β-D-psicopyranosyl-α-D-psicofuranose and 6-O-β-D-psicopyranosyl-β-D-psicofuranose, is used to convert allulose through a heating process, achieving high conversion rates and minimal by-product formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional chemical or enzymatic methods are used to prepare allulose, then the synthesis and purification processes become complex and difficult, but the patent achieves simplified preparation through a novel precursor composition
Solution Approach 1:
The patent applies preliminary action by pre-synthesizing allulose precursors (specifically psicose disaccharides with specific structural configurations) before the final allulose preparation step. This preliminary preparation of precursors with optimized molecular structures enables the subsequent isomerization to proceed more easily and efficiently, reducing the overall complexity of the manufacturing process.
Solution Approach 2:
The patent utilizes parameter changes by altering the molecular structure parameters of the sugar precursors. Specifically, it employs psicose-based disaccharides with particular glycosidic bond configurations (α-1,4; α-1,6; β-1,4; or β-1,6 linkages) that, when isomerized, produce allulose with enhanced ease of preparation compared to conventional methods.
2Manufacturing precision
If allulose is prepared without a novel precursor composition, then purification becomes difficult, but the patent achieves high purity allulose through specific precursor selection
Solution Approach 1:
The patent applies local quality by selecting precursors with specific local molecular characteristics - namely psicose disaccharides with particular glycosidic bond types (α-1,4; α-1,6; β-1,4; or β-1,6) at specific positions. These localized structural features ensure that upon isomerization, the resulting allulose maintains high purity with minimal impurities requiring purification.
Solution Approach 2:
The patent employs copying by using psicose disaccharide structures that are molecular copies or analogs of the desired allulose structure. The precursors are designed to mirror the target allulose molecular configuration, ensuring that the isomerization process produces high-purity allulose that closely replicates the desired structural parameters.
