Solution Overview

Problem

High-purity rebaudioside A stevia sweeteners exhibit unpleasant tastes such as aftersweetness and bitterness, and existing flavor improvers do not adequately enhance sweetness buildup and body while maintaining desirable flavor in food and beverages.

Innovation Solution

A stevia formulation comprising high-purity rebaudioside A combined with specific sugarcane-derived extracts and γ-aminobutyric acid, where the extracts are processed using porous adsorbents and solvents like methanol and ethanol, to reduce aftersweetness and bitterness while promoting rapid sweetness buildup and excellent flavor.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If high-purity rebaudioside A products are used as stevia sweeteners, then sweetness intensity is improved, but unpleasant tastes such as aftersweetness and bitterness occur

Engineering Contradiction:
Improvesweetness intensityVSAvoidaftersweetness and bitterness
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent introduces flavor improvers as intermediary substances that mediate between the stevia sweetener and the human taste system. These flavor improvers do not directly eliminate the bitter compounds but create a sensory bridge that masks bitterness and enhances desirable sweet notes, allowing high-purity rebaudioside A to maintain its sweetness intensity while reducing unpleasant aftertastes through sensory modulation

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a composite sweetener system by combining high-purity rebaudioside A with multiple flavor improvers in specific ratios. This composite formulation integrates the high sweetness intensity of pure rebaudioside A with the flavor-modifying properties of complementary substances, achieving a synergistic effect where the whole provides superior taste quality compared to the sum of its parts

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If flavor improvers are added to reduce unpleasant tastes, then aftersweetness and bitterness are reduced, but buildup of sweetness and body are insufficient

Engineering Contradiction:
Improveaftersweetness and bitternessVSAvoidbuildup of sweetness and body
Core Design Contradiction:
Object-affected harmful factorsVSDuration of action of moving object

Solution Approach 1:

The patent optimizes the concentration parameters of multiple flavor improvers simultaneously rather than adjusting a single substance. By precisely controlling the ratios of different flavor compounds within specific concentration ranges, the formulation achieves a balance where unpleasant tastes are suppressed while the temporal profile of sweetness buildup and body are enhanced through coordinated action of the compound system

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a dynamic flavor release profile by selecting flavor improvers with different volatility and solubility characteristics. These substances release their flavor-active components at different rates and times, creating a temporal sequence where initial sweetness buildup is rapid, followed by sustained body and suppressed aftertaste, rather than a static flavor profile

Inventive Principle:
Principle #15Dynamics

3Object-affected harmful factors

If flavor improvers are used to reduce bitterness, then unpleasant taste is reduced, but desirable flavor effect on food or beverage is suppressed

Engineering Contradiction:
ImprovebitternessVSAvoidsuppression of desirable flavor
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent applies local quality enhancement by selecting flavor improvers that specifically target and enhance particular desirable flavor notes (such as fruity, floral, or caramel notes) while leaving other flavor dimensions unaffected. This selective enhancement approach allows bitterness suppression without creating a blanket masking effect that would dull the overall desirable flavor character of the food or beverage

Inventive Principle:
Principle #3Local quality
