Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current water-based liquid food systems have insufficient solubility properties for certain ingredients, leading to stability issues, particularly in low pH environments, where flavors like citrus can be unstable and prone to oxidation and acid-catalyzed degradation.
Innovation Solution
A liquid system comprising a first and second component, selected from carbohydrates, sugar alcohols, food-grade acids, and non-aqueous solvents like glycerin, with a melting point lower than each component and containing 7% or less water, is used to stabilize ingredients against oxidation and acid degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water-based liquid food systems are used, then the system is simple and inexpensive, but solubility properties are insufficient and ingredient stability is poor
Solution Approach 1:
The patent uses composite liquid systems combining multiple components (sugars, polyols, acids, non-aqueous solvents) to create a eutectic mixture that provides both improved ingredient stability and solubility. The composite nature of the system allows synergistic effects that neither component achieves alone, resolving the contradiction between stability and complexity.
Solution Approach 2:
The patent changes key parameters of the liquid system including water content (reducing to 7% or less), pH level (maintaining low pH), and composition ratios to achieve optimal stability. By systematically adjusting these parameters, the system achieves high ingredient stability while maintaining reasonable complexity through defined compositional ranges.
2Reliability
If water content is reduced to improve solubility and stability, then ingredient stability improves, but the system becomes more complex to formulate
Solution Approach 1:
The patent defines specific parameter ranges including water content (≤7%), pH levels, and component ratios that simplify the formulation process. By establishing these defined parameters, the patent makes low-water formulation systematic and reproducible, reducing the complexity burden despite the reduced water content requirement.
Solution Approach 2:
The use of composite eutectic systems with multiple components in specific ratios creates a formulation framework that guides manufacturing. The defined composite structure provides clear formulation directions, making the reduced-water system easier to manufacture through established compositional guidelines.
3Adaptability or versatility
If citrus flavors are added to low pH aqueous systems, then flavor variety is enhanced, but the flavors become unstable and prone to degradation
Solution Approach 1:
The patent modifies the liquid system parameters (reducing water content to ≤7%, adjusting pH, changing composition) to create an environment where citrus flavors remain stable. These parameter changes prevent the degradation that occurs in traditional aqueous low-pH systems, allowing flavor variety without sacrificing stability.
Solution Approach 2:
The patent converts the typically harmful effect of low pH (which causes citrus flavor degradation) into a beneficial stable environment by removing water and creating a eutectic system. The low pH that would normally harm citrus flavors becomes part of a stable composite system that preserves them, turning a harmful factor into a beneficial one.
4Adaptability or versatility
If more ingredients are added to water-based systems, then product functionality is enhanced, but solubility limitations are exceeded and stability is compromised
Solution Approach 1:
The composite eutectic liquid system provides an enhanced solubility environment that can accommodate multiple ingredients (sweeteners, flavors, functional components) without exceeding solubility limits. The synergistic composite structure allows greater ingredient diversity while maintaining system stability, resolving the contradiction between functionality and stability.
