Solution Overview

Problem

The clinical and dietary use of isothiocyanates from crucifers, such as sulforaphane, is limited due to their chemical instability and variable enzymatic conversion by gut microbiota, making it difficult to formulate and deliver effective health benefits.

Innovation Solution

Activating myrosinase in Moringa oleifera plant material by injuring seeds or leaves at temperatures below 100°C, allowing for the conversion of glucosinolates into stable isothiocyanates without harsh conditions, enabling the production of a shelf-stable extract with high moringa isothiocyanate content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If isothiocyanates are used in their active form, then health benefits are improved, but chemical stability deteriorates

Engineering Contradiction:
Improvehealth benefitsVSAvoidchemical stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary action by pre-converting glucosinolates to isothiocyanates during plant material processing before consumption. The method involves injuring fresh plant material to activate myrosinase, which converts glucosinolates to isothiocyanates, and then drying the material while preserving the converted compounds. This preliminary conversion ensures health benefits are available without requiring the unstable active form to survive gastrointestinal conditions.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses glucosinolates as intermediary compounds that are stable in the plant material but can be converted to active isothiocyanates by myrosinase. These intermediary compounds serve as stable carriers of the bioactive isothiocyanate structures, protecting them from degradation until they reach the point of conversion in the consumer's digestive system or during controlled processing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If glucosinolates are consumed in their precursor form, then stability is improved, but enzymatic conversion efficiency deteriorates

Engineering Contradiction:
ImprovestabilityVSAvoidenzymatic conversion efficiency
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent applies preliminary action by performing the enzymatic conversion of glucosinolates to isothiocyanates during the processing of plant material before consumption. By injuring fresh plant material and activating myrosinase prior to drying and storage, the conversion is completed in advance, ensuring high productivity of the conversion process without relying on variable gut microbiota enzymatic activity.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If harsh conditions are applied to activate myrosinase, then conversion efficiency is improved, but compound degradation deteriorates

Engineering Contradiction:
Improveconversion efficiencyVSAvoidcompound degradation
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The patent applies parameter changes by using mild processing conditions (temperature below 100°C, avoiding harsh chemicals) to activate myrosinase and convert glucosinolates to isothiocyanates. This contrasts with conventional harsh methods that use high heat or strong acids/bases. The parameter change to milder conditions maintains conversion efficiency while preventing degradation of heat-sensitive and chemically labile compounds.
