Solution Overview

Problem

Wild and cultivated mushrooms often contain foreign elements like insects, topsoil, and other impurities, which are difficult to remove effectively, leading to inconsistent organoleptic characteristics and market withdrawal risks for processed products.

Innovation Solution

A process involving solvent extraction to separate soluble parts from mushrooms, followed by cleaning steps using pressure variations, gas bubbling, and oxygenated water to remove insoluble foreign elements, with reconstruction of the mushroom by combining cleaned pulp with the extracted solutes to achieve consistent flavor and aroma.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If wild mushrooms are used to maintain organoleptic characteristics, then flavor and aroma are improved, but contamination by insects and foreign elements increases

Engineering Contradiction:
Improveorganoleptic characteristicsVSAvoidinsect contamination
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The mushroom is divided into pulp and extract components. The pulp undergoes cleaning treatment while the extract is separated and later recombined, allowing selective removal of contaminants while preserving desirable organoleptic properties in the extract portion.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The soluble parts (extract) are extracted from the mushroom pulp using a solvent. This extraction separates the valuable organoleptic components from the insoluble foreign elements and insect contaminants, enabling selective cleaning of the pulp while preserving flavor and aroma in the extract.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of manufacture

If normal scrubbing processes are used to clean mushrooms, then external cleaning is achieved, but topsoil and internal contaminants remain

Engineering Contradiction:
Improvecleaning processVSAvoidcontaminant removal
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The mechanical scrubbing process is replaced with solvent extraction. The solvent penetrates the mushroom pulp to dissolve and extract soluble contaminants like topsoil residues and internal impurities, achieving thorough cleaning without mechanical damage to the mushroom structure.

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

Solution Approach 2:

A solvent is introduced as an intermediary substance to facilitate cleaning. The solvent acts as a medium that selectively dissolves and removes soluble contaminants from the mushroom pulp, enabling effective cleaning without direct mechanical contact that could damage the product.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If contaminated mushrooms are discarded to ensure product safety, then food safety is improved, but organoleptically excellent mushrooms are lost

Engineering Contradiction:
Improveproduct safetyVSAvoidmushroom yield
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The extract containing soluble contaminants is separated from the pulp through solvent extraction. This allows the pulp to be thoroughly cleaned and reconstructed with the extract, enabling the processing of mushrooms that would otherwise be discarded due to contamination while ensuring product safety.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The physical and chemical parameters of the mushroom are changed through solvent extraction and reconstruction. The process transforms contaminated raw mushrooms into cleaned, reconstructed products with controlled organoleptic properties, expanding the usable supply beyond traditionally acceptable mushrooms.

Inventive Principle:
Principle #35Parameter changes

4Adaptability or versatility

If mushroom batches with different characteristics are processed, then raw material availability is improved, but product consistency deteriorates

Engineering Contradiction:
Improveraw material acceptanceVSAvoidproduct consistency
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The mushroom is segmented into pulp and extract components that can be independently processed and then recombined in controlled proportions. This segmentation allows standardization of the final product by controlling the ratio and characteristics of the reconstructed components, ensuring consistency despite variations in raw material.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The reconstruction process creates a homogeneous final product by combining cleaned pulp with standardized extract. The extract serves as a consistent flavor and aroma component that uniformizes the organoleptic characteristics across batches, ensuring product consistency regardless of raw material variations.

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 process ensures repeatable organoleptic characteristics, reduces discards, and enhances the intensity of flavor and aroma, resulting in a consistent end product with a stronger aromatic component, while maintaining the fibrous structure, thus addressing the challenge of inconsistent mushroom quality.

Implementation Method 1

separation of the soluble parts from the mushrooms through the generation of an extract through solvent

Methodology Applied
Scientific EffectSolvent extraction: Liquid-Liquid Extraction

Implementation Method 2

suspending the pulp in a liquid medium, preferably water, to form a mixture, and the stressing of the mixture through at least one series of pressure variations that cause the foreign elements to come out

Methodology Applied
Scientific EffectPressure variations: Pressure Gradient

Implementation Method 3

bubbling through the mixture of a food gas or of a mixture of food gases (for example it is preferable to bubble at least nitrogen gas and/or carbon dioxide), where the bubbling of the gas causes the foreign elements to come out from the pulp in suspension

Methodology Applied
Scientific EffectGas bubbling: Sparging

Implementation Method 4

the pulp is placed in suspension in a solution comprising oxygenated water, to generate a mixture, for a predetermined time, where the reaction of the oxygenated water inside the pulp generates a propulsion effect that causes the foreign elements to come out

Methodology Applied
Scientific EffectOxygenated water reaction: Oxidation
