Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emulsion compositions used for clouding agents in drinks face challenges in maintaining stability over time and under harsh conditions due to their thermodynamically unstable nature, leading to separation issues and loss of opacity.
Innovation Solution
Incorporating gum arabic with a weight average molecular weight between 1 million and 5 million, combined with a specific amount of salt (1-10% by mass) such as sodium chloride, to enhance emulsion stability and maintain cloudiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional emulsion compositions are used to create cloudiness in drinks, then the desired opaque appearance is achieved, but the emulsion stability deteriorates over time and under harsh conditions
Solution Approach 1:
The patent changes the molecular weight parameter of gum arabic to a specific range (1-5 million) and optimizes the salt concentration parameter (1-10% by mass) to achieve improved emulsion stability while maintaining cloudiness. This parameter optimization resolves the contradiction between initial cloudiness appearance and long-term stability maintenance.
Solution Approach 2:
The patent creates a composite emulsion system by combining gum arabic with specific molecular weight characteristics and salt components. This composite approach enhances the overall emulsion stability and reliability of cloudiness maintenance compared to conventional single-component emulsion systems.
2Illumination intensity
If gum arabic is used as a clouding agent, then cloudiness is achieved, but the emulsion separates into immiscible liquids over time
Solution Approach 1:
The patent optimizes the molecular weight parameter of gum arabic (1-5 million) and controls salt concentration (1-10% by mass) to maintain both cloudiness and emulsion homogeneity. This parameter control prevents phase separation while preserving the desired opaque appearance.
Solution Approach 2:
The patent uses salt as an intermediary component that mediates between the hydrophilic gum arabic and hydrophobic oil phase. This intermediary role enhances the stability of the emulsion interface, preventing separation while maintaining cloudiness.
3Ease of manufacture
If demetallized gum arabic is used to improve emulsifiability, then emulsion formation is enhanced, but emulsion stability under harsh conditions deteriorates
Solution Approach 1:
The patent changes the molecular weight parameter of gum arabic to a higher range (1-5 million) and optimizes salt concentration (1-10% by mass) to achieve both ease of emulsion formation and stability under harsh conditions. This differs from conventional demetallized gum arabic by focusing on molecular weight rather than just metal content removal.
Solution Approach 2:
The patent creates a composite system combining gum arabic with specific molecular weight characteristics and salt components, providing both ease of manufacture and reliability under harsh conditions through synergistic interactions between components.
