Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for obtaining natural flavorings are economically inefficient due to the use of organic solvents and energy-intensive separation processes, and alternative solvent-free methods are complex and laborious, especially on an industrial scale.
Innovation Solution
A method involving a gaseous composition of flavoring substances being brought into contact with a molecular sieve having a pore diameter of at most 8 Å, allowing for the adsorption and separation of flavoring substances, which can then be easily added to products, reducing unwanted components and simplifying the separation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If organic solvents are used for extraction, then flavoring substances can be obtained, but additional costs and energy-consuming separation are required
Solution Approach 1:
The patent uses molecular sieves with specific pore sizes (3-10 Å) to selectively adsorb flavoring substances from gaseous compositions. The porous structure allows only molecules of specific sizes to enter and be retained, enabling separation without organic solvents or energy-intensive distillation processes.
Solution Approach 2:
The patent extracts flavoring substances by passing gaseous compositions through columns containing molecular sieves. The molecular sieves selectively adsorb the flavoring substances from the gas phase, separating them from unwanted components through size-based molecular recognition rather than solvent extraction.
2Ease of manufacture
If vacuum heating method is used, then solvent-free extraction is achieved, but complex process steps and large water separation are required
Solution Approach 1:
The patent replaces the complex mechanical vacuum heating system with a simpler adsorption-based system. Instead of heating materials under vacuum and then separating large amounts of water, the invention uses molecular sieves to directly adsorb flavoring substances from gaseous compositions at ambient or moderate temperatures, eliminating the need for vacuum equipment and water separation infrastructure.
3Manufacturing precision
If molecular sieve with pore diameter of at most 8 Å is used, then flavoring substances are obtained with enhanced purity, but adsorber composition requirements increase
Solution Approach 1:
The patent applies the principle of local quality by using molecular sieves with specifically tailored pore sizes (3-10 Å) that match the dimensions of target flavoring substance molecules. This localized structural feature enables selective adsorption based on molecular size, achieving high purity separation without requiring complex multi-component adsorber systems.
