Solution Overview

Problem

Highly purified steviol glycosides from the Stevia Rebaudiana plant exhibit non-sweet taste attributes like bitterness and low water solubility, which hinder their commercialization and application in food and beverage products, with Rebaudioside B (Reb B) being underutilized and viewed as an impurity rather than a potential sweetener.

Innovation Solution

A process is developed to create blends of Reb B with other steviol glycosides and sweeteners from various groups, including natural and synthetic sources, to enhance solubility and impact the taste profile, resulting in a more soluble and effective sweetener composition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If highly purified steviol glycosides are used, then sweetness intensity is improved, but non-sweet taste attributes (bitterness, astringency) increase

Engineering Contradiction:
Improvesweetness intensityVSAvoidbitterness and astringency
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The patent combines multiple steviol glycosides (stevioside, rebaudioside A, rebaudioside C, and rebaudioside B) in specific proportions to create a blended composition. This merging of different glycoside types produces synergistic effects that enhance overall sweetness while the presence of rebaudioside B specifically helps mask bitterness and astringency, resolving the contradiction between high sweetness intensity and unpleasant taste attributes

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention creates a composite sweetener material consisting of a multi-component steviol glycoside mixture rather than using a single purified glycoside. This composite approach allows the different glycosides to work together, where rebaudioside B acts as a flavor modifier that suppresses the harmful bitter and astringent notes while maintaining high sweetness, thus resolving the taste quality contradiction

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If highly purified steviol glycosides are used, then sweetness potency is improved, but water solubility decreases

Engineering Contradiction:
Improvesweetness potencyVSAvoidwater solubility
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent merges steviol glycosides with different solubility characteristics into a single composition. By combining highly potent but less soluble glycosides with other components, the overall mixture achieves improved water solubility while maintaining high sweetness potency, as the different components interact to enhance dissolution properties

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If rebaudioside B is considered an impurity and removed, then purification level is improved, but sweetness profile and solubility are worsened

Engineering Contradiction:
Improvepurification levelVSAvoidsweetness profile and solubility
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent converts rebaudioside B from being viewed as a harmful impurity to being utilized as a beneficial component. By intentionally including rebaudioside B in the composition, the invention transforms what was previously considered a defect into an asset that improves sweetness profile, masks bitterness, and enhances water solubility, thereby resolving the contradiction between purification and functional performance

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
