Solution Overview

Problem

The production of soluble coffee often results in an inferior product due to high processing temperatures and pressures, leading to undesirable off-flavors and aroma loss, and existing enzyme-based methods complicate the process with residual stabilizers in the final product.

Innovation Solution

Stabilized enzyme compositions using coffee-derived materials, which eliminate conventional stabilizers and enhance enzyme stability during storage and processing, allowing for the production of soluble coffee with retained flavor and aroma without additional formulation ingredients.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional stabilizers (sugars, polyols, salts, proteins) are added to enzyme formulations, then enzyme stability and activity are preserved during storage and processing, but the final soluble coffee product contains residual stabilizers that complicate the process and may affect product quality

Engineering Contradiction:
Improveenzyme stabilityVSAvoidprocess complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and removes conventional stabilizers (sugars, polyols, salts, proteins) from the enzyme formulation process. Instead of adding these external stabilizing agents, the invention uses coffee-derived materials that are naturally present in coffee extracts to stabilize the enzyme, thereby eliminating the need for separate stabilizer addition and subsequent removal steps

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The coffee-derived materials serve dual functions: they are both the stabilizing agent for the enzyme and a component of the final coffee product. This self-service approach eliminates the need for separate stabilizer ingredients, simplifying the overall process while maintaining enzyme stability

Inventive Principle:
Principle #25Self-service

2Productivity

If high processing temperatures and pressures are used in soluble coffee production, then extraction efficiency is improved, but undesirable off-flavors are generated and aroma is lost

Engineering Contradiction:
Improveextraction efficiencyVSAvoidoff-flavors
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces high-temperature thermal processing with enzymatic processing. Instead of using heat and pressure to extract coffee components, the invention uses enzymes (such as cellulases, hemicellulases, pectinases, and proteases) to chemically break down coffee solids at lower temperatures, thereby maintaining flavor and aroma while achieving efficient extraction

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention changes the processing parameters from high temperature/pressure (thermal-mechanical) to low temperature/enzymatic action (chemical-biological). This parameter transformation allows extraction to occur at temperatures that preserve volatile aromatic compounds while still achieving effective solubilization of coffee components

Inventive Principle:
Principle #35Parameter changes

3Duration of action of stationary object

If conventional stabilizers are used in enzyme formulations, then enzyme activity is maintained during storage, but additional formulation ingredients are required that increase manufacturing complexity and costs

Engineering Contradiction:
Improveenzyme activity durationVSAvoidmanufacturing simplicity
Core Design Contradiction:
Duration of action of stationary objectVSEase of manufacture

Solution Approach 1:

The coffee-derived materials perform multiple functions simultaneously: they serve as the stabilizing agent for the enzyme, provide buffering capacity for pH control, and are themselves desirable components of the final coffee product. This multi-functionality eliminates the need for separate stabilizer, buffer, and flavoring ingredients, thereby simplifying manufacturing

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

Solution Approach 2:

The invention uses homogeneous coffee-derived materials (such as coffee extracts, spent coffee grounds, or coffee solubles) as the stabilizing agent, which are naturally compatible with the final coffee product. This homogeneity ensures uniform distribution and compatibility throughout the formulation, simplifying manufacturing compared to multi-component systems with different stabilizers

Inventive Principle:
Principle #33Homogeneity

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The use of coffee-derived materials in enzyme compositions maintains enzyme stability and activity, reducing processing complexity and costs, while producing a soluble coffee product with balanced flavor and aroma similar to traditional roast and ground coffee.

Implementation Method 1

The mechanism (mode of action) of the stabilization is not always well known; but appears to involve protection of the enzyme protein (or in some cases, non-protein entity required for activity) from the denaturing or deactivating of thermal extremes, desiccation, shear, osmotic stress, pH stress, ionic gradients, proteolysis and other adverse forces.
