Dextrin-Based Solid Composition for Linalool and Geraniol Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to retain linalool and geraniol at high concentrations in solid compositions, which are essential for achieving a strong floral scent in tea beverages, as these components are prone to volatilization during production.
Innovation Solution
Incorporating polymer dextrin into the solid composition, particularly with a molecular weight of 50,000 or more, helps retain linalool and geraniol at high concentrations, ensuring a strong floral scent when the composition is made into a beverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional concentration methods (evaporation, freeze concentration, membrane concentration) are used to produce solid composition, then concentration efficiency is improved, but linalool and geraniol are lost due to volatilization and thermal degradation
Solution Approach 1:
The patent introduces a specific carrier substance (cyclodextrin or hydrocolloid) as an intermediary to bind and protect linalool and geraniol during the concentration process. This carrier acts as a mediator that prevents direct exposure of the aromatic components to thermal and volatilization stresses, thereby reducing loss while maintaining concentration efficiency.
Solution Approach 2:
The patent changes the molecular weight parameter of the carrier substance to ≥50,000, which fundamentally alters the concentration dynamics. This parameter change enables the carrier to retain aromatic components more effectively during concentration while maintaining solubility and processability, thus improving both concentration efficiency and retention rate.
2Ease of operation
If dextrin with low molecular weight is used in spray drying, then solubility of instant tea is improved, but retention of linalool and geraniol is insufficient
Solution Approach 1:
The patent changes the molecular weight parameter of dextrin from conventional low values to ≥50,000. This parameter change creates an optimal balance where the larger molecular structure provides better retention of aromatic components through enhanced binding capacity, while the water-soluble nature of dextrin maintains excellent solubility properties for instant tea preparation.
