Solution Overview

Problem

Conventional cocoa bean processing methods result in the destruction of cellular compartments due to high mechanical loads and heat, leading to emulsification of cocoa fats, making phase separation difficult and inefficient, and compromising the retention of desirable flavors, antioxidants, and vitamins.

Innovation Solution

A method involving wet grinding of cocoa beans with water to achieve particle sizes of 40 micrometers or less, heating to 70 degrees Celsius or less, and decantation to separate into three phases, utilizing water as a solvent to enhance extraction without high pressures, allowing for better separation and preservation of cocoa components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If high mechanical loads and heat are used to extract cocoa fats, then extraction efficiency is improved, but cellular compartments are destroyed causing emulsification and making phase separation difficult

Engineering Contradiction:
Improveextraction efficiencyVSAvoidphase separation difficulty
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent changes the parameters of mechanical extraction by controlling particle size reduction to a specific range and limiting the duration and intensity of mechanical treatment. This allows sufficient cocoa fat extraction while preventing complete cellular compartment destruction that leads to emulsification. The modified parameters enable both efficient extraction and maintainable phase separation.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If high mechanical loads are applied to extract cocoa fats, then extraction efficiency is improved, but desirable flavors, antioxidants, and vitamins are compromised

Engineering Contradiction:
Improveextraction efficiencyVSAvoidretention of desirable components
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies partial mechanical action - sufficient to extract cocoa fats but not excessive enough to completely destroy cellular compartments and release all desirable components. By controlling the degree of mechanical treatment, the process achieves adequate fat extraction while preserving flavors, antioxidants, and vitamins that would otherwise be compromised by more intensive processing.

Inventive Principle:
Principle #16Partial or excessive action

3Reliability

If water is used as a solvent for extraction, then preservation of cocoa components is improved, but extraction efficiency may be reduced compared to conventional methods

Engineering Contradiction:
Improvepreservation of cocoa componentsVSAvoidextraction efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent uses water as an intermediary solvent that facilitates extraction of cocoa components while being gentler than conventional solvents. Water acts as a mediator that can extract desirable components including flavors, antioxidants, and vitamins without the harsh effects of stronger solvents, thereby preserving the quality of extracted materials while maintaining acceptable extraction efficiency through controlled mechanical treatment.

Inventive Principle:
Principle #24Intermediary (Mediator)
