Solution Overview

Problem

Existing methods are inadequate for universally and effectively masking the grassy smell from n-hexanal in various food and beverage products without affecting the flavor and taste.

Innovation Solution

The use of specific flavor compounds such as oleic acid, β-damascenone, 4-methyl-2-phenyl-2-pentenal, menthyl 3-hydroxybutyrate, dimethyl benzyl carbinyl butyrate, and methyl 4-TERT-butylphenylacetate, optionally combined with 2,3-hexanedione, thymol, lauric acid, carvacrol, and isoambrettolide, to suppress n-hexanal odor in food and beverage products.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional masking substances (e.g., E-beta-damascone, beta-ionone, nootkatone) are used to mask n-hexanal odor, then the grassy smell is suppressed, but the flavor and taste of the food or beverage product are impaired

Engineering Contradiction:
Improven-hexanal odorVSAvoidflavor and taste impairment
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent changes the chemical parameters by selecting specific compounds with particular molecular structures and functional groups (carboxylic acids, ketones, aldehydes, esters, phenols, lactones) that have different interaction mechanisms with n-hexanal compared to conventional masking agents. This parameter change allows effective odor suppression while preserving flavor characteristics

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite flavor compositions containing multiple compounds working synergistically. The combination of compounds from different chemical classes (e.g., oleic acid with β-damascenone, or combinations including 2,3-hexanedione, thymol, lauric acid, carvacrol, and isoambrettolide) creates a composite masking effect that suppresses n-hexanal odor more effectively while maintaining natural flavor profiles better than single compounds

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If a universal masking method for n-hexanal is developed, then applicability to various food and beverage products is improved, but the complexity of selecting and optimizing flavor compounds increases

Engineering Contradiction:
Improveapplicability to various productsVSAvoidcompound selection and optimization complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent identifies compounds with broad applicability across different food and beverage matrices (plant-based proteins, soybeans, processed meats, fats and oils). The selected compounds function universally to mask n-hexanal odor through common mechanisms (olfactory receptor interaction, volatility modulation) while adapting to different product types, reducing the need for product-specific formulation development

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent establishes specific concentration ranges and formulation parameters that optimize masking effectiveness while simplifying the selection process. By defining effective concentration windows and compound ratios, the patent reduces the complexity of optimizing flavor compositions for universal application across different product types

Inventive Principle:
Principle #35Parameter changes
