Solution Overview

Problem

Steviol glycosides have low dissolution rates in aqueous solutions, limiting their effectiveness as high-intensity sweeteners in food and beverages.

Innovation Solution

Incorporating a steviol glycoside dissolution enhancer compound, such as caffeic acid esters or dicaffeoylquinic acids, to increase the dissolution rate of steviol glycosides in aqueous solutions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If steviol glycosides are used as high-intensity sweeteners, then sweetness intensity is improved, but dissolution rate deteriorates

Engineering Contradiction:

Core Design Contradiction:

Quantity of substanceVSSpeed

Solution Approach 1:

The patent introduces dissolution enhancer compounds as intermediary substances that facilitate the dissolution of steviol glycosides. These enhancers act as mediators between the poorly dissolving steviol glycosides and the aqueous environment, enabling improved dissolution rates while preserving the high sweetness intensity of the original compound.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates composite formulations by combining steviol glycosides with dissolution enhancer compounds. This composite approach allows the system to simultaneously achieve high sweetness intensity from the steviol glycoside and improved dissolution rate from the enhancer compound, resolving the contradiction between these two properties.

Inventive Principle:
