Trehalose Particulate Composition Emulsifying Stability Trade-off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional particulate compositions containing crystalline trehalose dihydrate lack emulsifying ability, failing to effectively disperse oily substances in water, limiting their applications in fields such as foods and cosmetics.
Innovation Solution
A particulate composition with crystalline trehalose dihydrate is developed by preparing a saccharide solution with trehalose and maltose/maltotriose in specific ratios, followed by spray-drying and aging under controlled humidity to achieve a degree of crystallinity that enhances emulsifying ability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional crystalline trehalose dihydrate is used, then storage stability is improved, but emulsifying ability deteriorates
Solution Approach 1:
The invention creates a composite particulate composition containing both crystalline trehalose dihydrate and amorphous trehalose, along with maltose and/or maltotriose. This composite structure combines the storage stability of crystalline form with the emulsifying properties of amorphous form and other saccharides, resolving the contradiction between stability and functionality.
Solution Approach 2:
The invention applies local quality by maintaining different physical states (crystalline and amorphous) of trehalose within the same particulate composition. The crystalline portions provide stability while the amorphous portions provide emulsifying ability, allowing different regions of the material to fulfill different functional requirements.
2Manufacturing precision
If trehalose purity is increased to 98% or higher, then product quality is improved, but emulsifying ability deteriorates
Solution Approach 1:
The invention changes the purity parameter from conventional 98% or higher to 70-97%, and simultaneously introduces other saccharides (maltose and/or maltotriose) at 3-30%. This parameter modification enables the material to gain emulsifying ability while maintaining adequate trehalose content for stability.
Solution Approach 2:
By creating a composite saccharide system rather than pure trehalose, the invention achieves both adequate purity (70-97%) and emulsifying ability through the synergistic combination of multiple saccharide components with different functional properties.
