Solution Overview
Problem
Pyrroloquinoline quinone deposition occurs in acidic beverages when ascorbic acid is present, leading to stability issues.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ascorbic acid is added to acidic beverages to adjust pH and prevent oxidation, then the beverage stability and antioxidant properties are improved, but pyrroloquinoline quinone deposition occurs
Solution Approach 1:
Cyclodextrin acts as an intermediary substance that forms an inclusion complex with pyrroloquinoline quinone. The cyclodextrin molecule has a hydrophobic cavity that accommodates the pyrroloquinoline quinone, preventing its direct interaction with ascorbic acid and subsequent deposition. This mediator approach resolves the contradiction by allowing ascorbic acid to maintain its pH adjustment and antioxidant functions while cyclodextrin protects pyrroloquinoline quinone from deposition.
Solution Approach 2:
The invention creates a composite system where cyclodextrin and pyrroloquinoline quinone form an inclusion complex. This composite structure combines the properties of both components: cyclodextrin provides solubility enhancement and stabilization, while pyrroloquinoline quinone maintains its biological activity. The composite material approach allows the coexistence of ascorbic acid and pyrroloquinoline quinone in the same beverage without deposition issues.
2Quantity of substance
If pyrroloquinoline quinone is added to acidic beverages for health benefits, then the nutritional value is improved, but deposition occurs reducing product quality
Solution Approach 1:
Cyclodextrin serves as a mediator that enhances the solubility of pyrroloquinoline quinone in the acidic beverage matrix. By forming an inclusion complex, cyclodextrin allows higher concentrations of pyrroloquinoline quinone to be maintained in solution without precipitation, thereby improving both the quantity of active substance and the consistency of product quality.
Solution Approach 2:
The addition of cyclodextrin changes the physical-chemical parameters of the system, specifically improving the solubility characteristics of pyrroloquinoline quinone. This parameter change enables the maintenance of consistent pyrroloquinoline quinone concentrations throughout the beverage shelf life, ensuring manufacturing precision and product quality consistency while maximizing the nutritional content.
3Stability of the object's composition
If cyclodextrin is added to suppress pyrroloquinoline quinone deposition, then the solution stability is improved, but the beverage formulation complexity increases
Solution Approach 1:
Cyclodextrin is a well-established food-grade ingredient commonly used in beverage formulations for its solubility-enhancing properties. By selecting cyclodextrin as the intermediary, the formulation leverages an already-approved substance with known safety and functionality, minimizing regulatory and formulation complexity while effectively suppressing pyrroloquinoline quinone deposition.
Solution Approach 2:
Cyclodextrin provides multiple functions in the beverage formulation: it acts as a solubility enhancer for pyrroloquinoline quinone, a stabilizer preventing deposition, and a potential flavor modifier. This multi-functionality reduces the need for additional separate additives, thereby simplifying the overall formulation despite the added stability requirement.
