Polyphenol Solubility via Cyclodextrin Inclusion Complexes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Polyphenols and flavonoids have limited solubility in water, leading to precipitation in food formulations, which affects product quality and consumer acceptance, and existing solutions either have inadequate taste or limited storage stability.
Innovation Solution
A mixture of polyphenols, flavonoids, or diterpene glucosides combined with polysaccharides and saponins, where the polysaccharides have a high arabinogalactan protein content, allowing for the production of dry powders or granules with improved solubility and taste properties, including enhanced fruit notes and bitterness masking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polyphenols and flavonoids are incorporated into food formulations, then health-promoting properties and taste are improved, but solubility decreases and precipitation occurs
Solution Approach 1:
The patent uses cyclodextrins as intermediary molecules that form inclusion complexes with polyphenols and flavonoids. The cyclodextrins act as mediators between the hydrophobic active ingredients and the aqueous food matrix, improving solubility and preventing precipitation while maintaining stability.
Solution Approach 2:
The invention creates composite formulations by combining polyphenols/flavonoids with cyclodextrins and other compatible carriers. This composite approach allows the hydrophobic active ingredients to be dispersed in hydrophilic matrices through the cyclodextrin inclusion complexes, resolving the solubility-stability contradiction.
2Stability of the object's composition
If spray-drying is used to improve stability, then storage stability increases, but taste quality deteriorates
Solution Approach 1:
The patent modifies the drying parameters and formulation composition to minimize taste deterioration. By optimizing the cyclodextrin-to-active-ingredient ratio and controlling drying conditions, the formulation maintains better taste profiles after spray-drying compared to conventional approaches.
3Object-generated harmful factors
If liquid solubilizing agents are used to improve taste, then mouthfeel improves, but storage stability decreases
Solution Approach 1:
The invention utilizes phase transition from liquid to solid form through spray-drying. The liquid solubilizing system with cyclodextrins provides good mouthfeel, and the phase transition to dried powder form enhances storage stability, allowing the formulation to exhibit both desirable taste properties and improved stability.
4Quantity of substance
If active ingredient content is increased to improve efficacy, then health benefits increase, but solubility and stability worsen
Solution Approach 1:
Cyclodextrins serve as mediators that enable higher active ingredient loading by forming stable inclusion complexes. This allows increased polyphenol and flavonoid content while maintaining solubility, as the cyclodextrins prevent aggregation and precipitation of the hydrophobic compounds.
