Solution Overview

Problem

Current treatments for hyperinsulinaemia, particularly in type-2 diabetes and obesity, often stimulate insulin secretion, whereas there is a need for agents that reduce blood sugar levels without increasing insulin secretion.

Innovation Solution

The use of yeast cell walls with a high total glucan and mannan content, obtained through autolysis or enzymatic hydrolysis, which are insoluble and have low glycogen content, to regulate insulin levels by acting as an insulin-regulating agent, specifically for the treatment and prevention of hyperinsulinaemia.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If conventional treatments are used to reduce blood sugar levels, then glycaemia is reduced, but insulin secretion is stimulated (hyperinsulinism worsens)

Engineering Contradiction:
Improveblood sugar levelVSAvoidinsulin secretion stimulation
Core Design Contradiction:
TemperatureVSObject-generated harmful factors

Solution Approach 1:

The patent extracts and utilizes specifically the cell wall fraction of yeast, separating it from the complete yeast cell. This extracted cell wall fraction (containing β-glucans and mannans) acts independently to reduce blood sugar without stimulating insulin secretion, thus resolving the contradiction between glycaemia reduction and insulin secretion control

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The yeast cell wall fraction acts as an intermediary substance between dietary carbohydrates and blood sugar regulation. It interferes with carbohydrate digestion and absorption processes, providing a mediating mechanism that lowers blood sugar levels through alternative pathways that do not involve insulin secretion stimulation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If complete yeast cells are used, then all nutritional components are provided, but glycogen content is high (24.9%) which is not part of the cell wall

Engineering Contradiction:
Improvenutritional componentsVSAvoidcell wall purity
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The patent applies extraction by using enzymatic hydrolysis with proteases to solubilize and remove non-cell wall components (proteins, glycogen, trehalose) from complete yeast cells, leaving behind the purified cell wall fraction with high β-glucan and mannan content

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the physical-chemical parameters of the yeast material through controlled enzymatic hydrolysis conditions (protease treatment, temperature, time) to selectively solubilize unwanted components while preserving the cell wall structure, achieving the desired composition with ≥34% total glucan and mannan and <10% glycogen

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If yeast cell walls are obtained by simple hydrolysis, then production is simple, but glycogen content remains high

Engineering Contradiction:
Improveproduction simplicityVSAvoidglycogen content control
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent introduces proteases as intermediary enzymes to mediate the hydrolysis process. These enzymes specifically target and solubilize protein-associated glycogen and other non-cell wall components, achieving precise glycogen reduction while maintaining production feasibility through a single additional enzymatic step

Inventive Principle:
Principle #24Intermediary (Mediator)
