Tea Aroma Composition Using 2-Methylbutanal Ratio
Solution Overview
Problem
There is a lack of effective aromatizing materials that provide excellent floral aroma for tea beverages, particularly high-grade green tea beverages.
Innovation Solution
A tea aroma composition comprising linalool, geraniol, and 2-methylbutanal, with a specific weight ratio of 2-methylbutanal to total linalool and geraniol within a range of 0.010 to 0.215, which can be combined with additional aroma components like 2,4-heptadienal and others, to enhance the floral aroma.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional aromatizing materials (linalool and geraniol only) are used, then the basic floral aroma is achieved, but the floral aroma quality is insufficient and not characteristic of high-grade tea leaves
Solution Approach 1:
The patent applies composite materials by combining linalool, geraniol, and 2-methylbutanal in specific ratios to create a composite aroma composition. This composite approach produces a superior floral aroma that is characteristic of high-grade tea leaves, resolving the contradiction between achieving reliable aroma quality and maintaining composition simplicity.
Solution Approach 2:
The patent applies parameter changes by optimizing the weight ratio of 2-methylbutanal to total linalool and geraniol content within the range of 0.010 to 0.215. This parameter optimization enables the aroma composition to achieve excellent floral aroma characteristic of high-grade tea, transforming the basic floral notes into a more refined and authentic tea-like floral aroma.
2Reliability
If the ratio of 2-methylbutanal to linalool and geraniol is outside the specified range, then the composition is simpler to manufacture, but the floral aroma quality deteriorates
Solution Approach 1:
The patent establishes a specific parameter range (weight ratio of 2-methylbutanal to total linalool and geraniol content of 0.010 to 0.215) that optimizes floral aroma quality. This parameter specification resolves the contradiction by defining the precise conditions needed to achieve excellent floral aroma while providing clear manufacturing guidance.
Solution Approach 2:
The patent copies the natural aroma profile of high-grade tea leaves by identifying and replicating the specific ratio of aromatic components found in premium tea. This copying approach allows manufacturers to reproduce authentic tea floral aroma without needing to source rare or complex natural materials.
3Reliability
If steam distillation method is used to produce aromatizing materials, then the production process is established and reliable, but the floral aroma quality is insufficient for high-grade tea beverages
Solution Approach 1:
The patent applies parameter changes by modifying the composition parameters of steam distillation products through the addition of 2-methylbutanal in controlled ratios. This allows the use of the established steam distillation process while achieving superior floral aroma quality that was previously unattainable through steam distillation alone.
Solution Approach 2:
The patent creates a composite aroma material by combining steam distillation extracts with 2-methylbutanal. This composite approach maintains the reliability of the steam distillation process while enhancing the floral aroma quality to meet the requirements of high-grade tea beverages.
