Solution Overview

Problem

The alkalization process in chocolate production reduces the nutritional value of cocoa by destroying antioxidants and requires high sugar content to achieve the desired flavor, contributing to health issues such as diabetes and obesity.

Innovation Solution

Using stable alkaline water produced by the Natralysis Process to alkalize cocoa natural products, allowing for the production of chocolate with high antioxidant content, reduced sugar, and added novel soluble ingredients, while maintaining the signature flavor and organoleptic properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If traditional alkalization process is used to enhance cocoa powder solubility and darken color, then solubility and color are improved, but antioxidant content is destroyed and nutritional value is reduced

Engineering Contradiction:
ImprovesolubilityVSAvoidantioxidant content
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

The patent applies parameter changes by using supercritical carbon dioxide (scCO2) instead of traditional alkali solutions. The supercritical state of CO2 (achieved by controlling temperature and pressure parameters) enables selective extraction and modification of cocoa components while preserving antioxidants. This alternative chemical environment achieves solubility enhancement without the destructive effects of conventional alkalization on flavonols and other antioxidants.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If traditional alkalization process is used to reduce bitter and acidic taste, then sensory characteristics are improved, but large quantities of sugar must be added which contributes to health issues

Engineering Contradiction:
Improvesensory characteristicsVSAvoidsugar content
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The patent uses supercritical carbon dioxide to selectively extract and remove bitter and acidic compounds from cocoa material. The scCO2 process enables targeted extraction of unwanted sensory components (bitterness and acidity) while leaving the desirable chocolate flavor profile intact. This extraction approach reduces the need for sugar addition to mask negative tastes, thereby lowering overall sugar content in the final product.

Inventive Principle:
Principle #2Taking out (Extraction)

3Quantity of substance

If strong alkalization is applied to achieve dark color and high solubility, then these properties are enhanced, but 90% of original antioxidants are destroyed

Engineering Contradiction:
ImprovesolubilityVSAvoidantioxidant content
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

The patent introduces supercritical carbon dioxide as an intermediary substance to mediate between the desired solubility enhancement and the preservation of antioxidants. The scCO2 acts as a gentle modifying agent that facilitates solubility improvement through alternative mechanisms (such as modifying the cocoa butter matrix or creating microencapsulation effects) without directly attacking and destroying antioxidant molecules, unlike strong alkali solutions.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

In the present application, alkalization of cocoa natural products may be carried out by using a stable alkaline water (pH levels of up to 10.5 or more) with the aim to produce alkalized chocolate products with pleasant organoleptic, less sugar content, less acidity, high antioxidants contents, and addition of novel soluble ingredients to chocolate. This can be achieved by using the stable alkaline water produced by a Natralysis Process in alkalizing cocoa nibspre, during and post grinding, alkalizing the cocoa liquor and alkalizing the natural cocoa powder. The present application discloses a method or apparatus (3, 9, 15) in which a cocoa natural product and/or one or more of its derivatives is alkalized by using stable alkaline water.
